11.00-12.30: Workshop

ICRI (International Collaborative Research Initiative) Workshop

The International Collaborative Research Initiative (ICRI) on Rolling Contact Fatigue and Wear of Rails and Wheels exists to identify and prioritize research topics in that specialized field and then to form international teams to collaboratively resolve prob-lems. The Initiative uses a model of volunteer cooperation among individuals and or-ganizations with a common interest in arriving at solutions to specific wheel/rail issues. The ICRI does not financially sponsor research, but instead relies on "in-kind" contribu-tions from persons and organizations already undertaking activities in the various areas, where there is already strong alignment with either their existing or planned activities and for which they already have or can obtain funding.

This workshop will bring together current and prospective ICRI participants to review, strategize and initiate research activities related to RCF and wear in railway systems. Ongoing projects include “Modelling of Friction”, “Quantifying the Magic Wear Rate” and “Wear Mapping”.

The ICRI always welcomes new ideas and contributors. All are invited to join the work-shop to learn about the ICRI and its ongoing activities, to identify possible synergies with their own activities, and participate in the development of new collaborative re-search activities.

Modernisation of Rail Tracks for Higher Speeds and Greater Freight B. Indraratna1,2, S. Nimbalkar1 and C. Rujikiatkamjorn3 1Centre for Geomechanics and Railway Engineering University of Wollongong, Australia 2ARC Centre of Excellence for Geotechnical Science and Engineering University of Wollongong, Australia 3School of Civil, Mining and Environmental Engineering University of Wollongong, Australia Abstract

An efficient transportation infrastructure has become one of the most important priori-ties for global economic reforms. Railways are designed to provide high speed passen-ger and heavy haul freight transportation. Ballast is one of the most important con-stituents of the rail track: however, it experiences excessive deformation and degrada-tion from trains operating at high speeds. In addition, tracks built along coastal areas often undergo large settlements as a result of soft compressible clay deposits. This leads to progressive track deterioration and necessitates frequent and costly track maintenance. The artificial inclusions, such as geogrids, geocomposites, shock mats, and prefabricated vertical drains (PVDs) are often used as attractive design alterna-tives for track practitioners. However, performances of these inclusions are predomi-nantly governed by their technical specifications in addition to geotechnical charac-terization of the track substructure, including ballast and subgrade. Therefore, full scale field trials were conducted on instrumented track sections built along the south-east coast of Australia (e.g. Bulli and Singleton). The performance of geogrids and geocomposite was evaluated in terms of specific key parameters, such as stiffness and aperture size of geogrids, placement location of geogrids, as well as subgrade types. It was also proven that the placement of shock mats (rubber pads) in rail tracks lead to the mitigation of particle breakage. An empirical approach to relate ballast strains to the number of load cycles is presented. The aspects of particle degradation and stresses applied by train paths are discussed. The use of PVDs to dissipate the excess pore pressure for increased stability of the soft clay subgrade is presented.

Railway Vehicle Dynamics under Degraded Adhesion Conditions: An Innovative HIL Architecture for Braking Tests on Full-Scale Roller-Rigs

B. Allota, R. Conti, E. Meli, L. Pugi and A. Ridolfi Department of Industrial Engineering University of Florence, Italy Abstract

In this paper an innovative hardware in the loop (HIL) architecture to test braking on board subsystems on full-scale roller-rigs is described. The new approach permits the reproduction of a generic wheel-rail adhesion pattern on the roller-rig and, in particu-lar, degraded adhesion conditions. The strategy presented is also followed by the inno-vative full-scale roller-rig of the Railway Research and Approval Center of Firenze-Osmannoro (Italy); the new roller-rig has been built by Trenitalia and is owned by SIMPRO. At this initial phase of the research activity a complete model of the HIL system has been developed to effectively validate the proposed approach. The com-plete numerical model is based on the real characteristics of the components provided by Trenitalia. The results coming from the simulation model have been compared to the experimental data provided by Trenitalia and consistent with ontrack tests per-formed in Velim, Czech Republic, with a UIC-Z1 coach equipped with a fully-working WSP system. The preliminary validation performed with the HIL model highlights the good performance of the HIL strategy in reproducing the complex inter-action between degraded adhesion conditions and railway vehicle dynamical behav-iour during the braking manoeuvre on the roller-rig.

Service Life Testing of Railroad Bearings with Known Subsurface Inclusions: Detected with Advanced Ultrasonic Technology

C.M. Tarawneh1, J.A. Turner2, L. Koester2 and B.M. Wilson3 1Mechanical Engineering Department University of Texas-Pan American, Edinburg, Texas 2Mechanical and Materials Engineering Department University of Nebraska, Lincoln, Nebraska 3Research and Development, Amsted Rail, Granite City, Illinois

Abstract Steel cleanliness is of the utmost importance in the production of tapered roller bear-ings used in the railroad industry. Impurities in the steel can make it vulnerable to fatigue initiation because they act as stress concentration sites in the fabricated parts, especially when these impurities are located in regions of susceptibility for rolling contact fatigue (RCF). Impurities present near the rolling surfaces (e.g., raceways in bearings) are referred to as subsurface inclusions. These subsurface inclusions make the steel susceptible to the initiation of fatigue cracks that can propagate towards the surface leaving a cavity called a “spall”. Spalls occurring on the rolling surfaces of bearings can have detrimental effects that may lead to overheated bearings, loss of full service life, and in extreme cases, can lead to derailments if not addressed in-service by early detection methods. The study presented in this paper investigates the effects of subsurface inclusions present beneath the surface of the bearing cup (outer ring) and cone (inner ring) raceways. New bearing components were scanned using a unique ultrasonic technique in order to detect and identify potentially detrimental subsurface inclusions present in the RCF regions of the rolling surfaces. Two service life tests of these components were then carried out: one to examine subsurface inclusions found on cone raceways, and one to explore subsurface inclusions present on cup raceways. The test results indicate that the service life of components containing subsurface inclusions is reduced com-pared to controls for which no subsurface inclusions were detected. Moreover, subsur-face inclusions on bearing cups appear to accelerate spall development relative to those present in bearing cones. This paper summarizes the findings of the experimen-tal study performed on ultrasonically scanned bearing components, and emphasizes the need to establish more refined methods to inspect railroad rolling stock. These results are anticipated to be of great value to fatigue life prediction models relevant to the railroad industry.

A Tribological View of Wheel-Rail Wear Maps Y. Zhu, J. Sundh and U. Olofsson Department of Machine Design The Royal Institute of Technology KTH Stockholm, Sweden Abstract

Wear in the railway wheel and rail contact is very closely related to the safety, mainte-nance and life cycle cost for the railway industry. An accurate prediction of wear is very important. Wear maps are commonly used as an input for simulating and predict-ing wheel/rail wear. These maps are often formulated for dry, unlubricated wheel/rail contacts at room temperature. In this study, wear maps were set up for different levels of humidity, contact pressure, sliding velocity and temperature, as well as with and without lubricant/oxide layers. Increasing the accuracy of wear maps requires separate maps for wheel tread/rail head and wheel flange/rail gauge contacts because there are significant differences in the contact conditions that cannot be included in a general wear map. The mild wear regime can be further divided into different areas instead of one constant wear coefficient as a result of environmental conditions and oxide layers.

Risk Analysis of Railway Vehicles under Strong Crosswinds C. Proppe and X. Zhang Karlsruhe Institute of Technology Institute of Engineering Mechanics Germany Abstract Sufficient crosswind stability is an important criterion in the approval process of rail-wayvehicles. Lightweight constructions and high driving velocities increase the risk of crosswind related accidents. For this reason, more and more studies about the stability of vehicles under strong crosswind are being carried out. As a result of the existence of turbulence, wind is a stochastic process. Realistic assumptions on the nature of the crosswind have to take its nonstationary character into account. To assess the stability of the vehicle being affected by a strong crosswind in a more realistic way, a stochas-tic gust model with nonstationary turbulence based on the NONAR method is pro-posed in this paper. The crosswind stability of a vehicle running on both straight track and curved track is studied. As the excitation of the vehicle is a stochastic process, a risk analysis has to be carried out and failure probabilities have to be computed. Based on the risk analysis, the influence of vehicle speed and track parameters has been ana-lyzed.

Performance Measurement for Managing Railway Infrastructure A. Parida, C. Stenström and U. Kumar Division of Operation, Maintenance and Acoustics Luleå University of Technology, Sweden Abstract An effective and efficient railway infrastructure is essential to assure asset perform-ance which is often measured in terms of high availability, high level of safety and good track quality, besides value addition. Thus, the measurement of asset mainte-nance performance has become an essential element of strategic thinking for railway asset owners and managers. The area of asset maintenance performance is relatively new and emerging, besides its complexity with regards to the many internal and exter-nal stakeholders, all with conflicting interests. The railway infrastructures’ overall objectives and strategies are required to be broken down through the hierarchical level, converting them into various key performance indicators (KPIs) for measure-ment, data collection, analysis, and decision making at appropriate levels through ag-gregation. This paper looks into some of the performance measurement issues of railways, and how these issues can be solved through data aggregation, analysis, simulation, and presentation. Following a discussion of these issues, a case study is carried out to demonstrate how performance can be analysed and presented.

Wheel Rail Contact: Theoretical and Experimental Analysis A. Alonso1,2, A. Guiral1,2 and J.G. Gimenez2 1CEIT, University of Navarra, San Sebastián, Spain 2TECNUN, University of Navarra, San Sebastián, Spain Abstract The importance of the wheel/rail contact problem in railway dynamics problems has led to the publication of many different mathematical methods. This paper summa-rizes the most important ones, underlining the assumptions made and their implication in the accuracy of the results. From this analysis, one of the main conclusions is that most of them tackle the wheel/rail contact problem mainly from a purely theoretical point of view, and that a theoretical/experimental comparison is required in order to analyse the influence of certain parameters not taken into account in the mathematical developments. Because of this, the second part of this paper summarizes the most important steps followed in building a scaled test-bench to experimentally character-ize the wheel/rail contact problem. The results of the longitudinal contact force as a function of the longitudinal creepage are obtained under different conditions; clean and dry, friction modifier, cutting fluid and sand. In addition, the divergences, with respect to Kalker’s Simplified Theory, are analyzed.

Railway Track Transition Zones: Design, Construction, Monitoring and Numerical Modelling E. Fortunato1, A. Paixão1 and R. Calçada2 1Transportation Department National Laboratory for Civil Engineering, Lisbon, Portugal 2Department of Civil Engineering Faculty of Engineering, University of Porto, Portugal Abstract Railway tracks frequently show higher degradation rates at transition zones from earthworks to bridges, or to other structures. In order to guarantee the safety and com-fort of passengers, this aspect results in higher maintenance costs and disturbs railway operations. The behaviour of transition zones is rather complex and its poor perform-ance has been mainly attributed to variations in the vertical stiffness of the track and to differential settlements. These two aspects amplify the dynamic loads of the trains and cause further track degradation. The Portuguese railway network manager has reported the poor structural behav-iour of a few transition zones in some of its lines, which constrain train operations and present high maintenance costs. Thus, a research project is currently underway aiming at contributing to a better understanding of the phenomena that occur at transitions, and at optimizing their design for conventional and high-speed railway lines. In this article, we present some aspects of this research project, namely: a review on the de-sign of backfills for transition zones; a comparison between numerical models found in the literature that were used to study the problem; some results obtained during the construction (characterization of materials and layers) and operation of the line.

Simulations of Running Dynamics for Vehicle Acceptance: Application and Validation O. Polach1 and J. Evans2 1Bombardier Transportation (Switzerland) AG Zürcherstrasse, Winterthur, Switzerland 2Interfleet Technology Limited Derby, United Kingdom Abstract Multi-body simulation tools are used in rolling stock design and development to opti-mise the vehicle parameters and to conduct a wide range of investigations. Although the vehicle acceptance is traditionally based on physical testing, the use of simulations as a part of vehicle authorisation is increasing. This state of the art paper reviews the recent status of conditions for the application of simulations in the context of vehicle authorisation and summarises the progress of investigations related to the methodol-ogy and criteria for a reliable model validation.

Wheel and Rail Profile Wear on Small Radius Curved Tracks and its Effect on Derailment Coefficients: Measurement and Simulation H. Sugiyama1, M. Yada2, H. Yamamoto2, J. Kurihara3 H. Ohbayashi3, Y. Shimokawa4, M. Mizuno4 and M. Tanimoto5 1Department of Mechanical and Industrial Engineering The University of Iowa, USA 2Department of Mechanical Engineering Tokyo University of Science, Japan 3Tokyo Metro Co., Ltd., Japan 4Nippon Steel & Sumitomo Metal Corporation, Japan 5Nippon Steel & Sumikin Technology Co., Ltd., Japan

Abstract In this investigation, the wheel and rail contact problem on small radius curved tracks for severely worn profiles, and its effect on the derailment coefficient of railroad vehi-cles, are discussed. The on-track condition monitoring system installed on small ra-dius curved tracks in the Tokyo subway is used to measure the wheel/rail contact forces over years. The measurement results on the curved rail that has a severely worn profile with plastic material flows around the gauge corner indicates that the derail-ment coefficient (L/V ratio) decreases as the wear level increases. To explain this phe-nomenon, the finite element contact analysis is performed first, for the measured worn wheel and rail profiles, and then the contact patches obtained by the finite element analysis are used to define the multi-Hertzian contact in the curve negotiation analysis on the small radius curved track. The numerical results indicate the same decreasing trend of the derailment coefficient as the wheel wear increases. It is demonstrated that the location of contact patches on the flange moves close to the top of the flange as the wear around the flange becomes significant, and it leads to the increase in the steering yaw moment, which explains the decreasing trend of the derailment coefficient ob-served in the measurement on the small radius curved track.

Rolling Stock Dynamic Evaluation by Means of Laboratory Tests A. Facchinetti1, S. Bruni1 and W. Zhang2 1Dipartimento di Meccanica Politecnico di Milano, Italy 2State Key Laboratory of Traction Power Southwest Jiaotong University, China Abstract Despite the recent progress and the extensive use of modelling and simulation tech-niques, physical testing remains a major instrument for the development and valida-tion of railway vehicles in respect to their running dynamics. Not only are the present vehicle acceptance procedures mostly based on physical rather than virtual tests, but testing is frequently used at different stages of the design process with diverse aims. In recent years, important developments have been introduced in the methods and facili-ties for laboratory tests on full vehicles and their sub-systems. The aim of this paper is to provide a survey of these recent developments.

Automation in Railway Operations: Challenges, Perspectives and Experimented Effects on System Performance S. Ricci Department of Civil, Environmental and Building Engineering Sapienza Università di Roma, Italy Abstract This paper is structured to depict a state-of-the-art of the progressive extension of “automation” within the railway system. It starts from definitions and concepts of automation, and from an overview of present and future potential applications to rail-way operation fields. The progressive migration process from “human managed” to “machine based” tasks fulfilment is analysed, as well as the present position along this process in various fields of railway traffic management. The historical basis of the migration are highlighted in the macro-sectors of infrastructures, vehicles, and opera-tion and services and, inside them, the specific fields are qualified with an assessment of the respective maturity levels. The analysis is particularly focused on the automa-tion contributions into the following macro-sectors: i) safety management, ii) dis-patching, iii) train operation. The safety management field is in-depth investigated: principles and objectives, links between safety and traffic density, man to machine transfers of safety critical functions and their full automation state-of-the-art and perspectives are covered. The dispatching field is a key sector for automation implementation and is analysed with a similar approach: objectives and standards, links between capacity and punctuality, man to machine migration of dispatchers’ actions, and further challenges of automatic dispatching systems are managed. The automation of train operation is the premise to a full automated train control, which is today a consolidated framework for mass tran-sit systems, with huge challenges in other fields of railway business (freight trains, marshalling terminals, etc.). Finally, an overview of priorities in railway research identified at European level (EC Horizon 2020, ERRAC Roadmaps, etc.) are analysed: the standardisation and the large implementation of automatic operation in critical (for safety and quality of ser-vices) and massive functions are identified as the most fruitful investigation area to-wards the general increase of the performances of the railway system.

Shape Optimization of Train Heads with respect to the Aerodynamic Loads on Track Side Objects C. Wagner1,2, G. Horstmann1, S. Herzog1, D. Jakubek1 and S. Rutschmann1 1Institute of Aerodynamics and Flow Technology, SCART German Aerospace Center, (DLR), Göttingen, Germany 2Institute of Thermodynamics and Fluid Mechanics Ilmenau University of Technology, Ilmenau, Germany Abstract Fast passing trains induce aerodynamic forces which can be dangerous for trackside objects and also for people in railway stations. Optimizing the shape of train heads with the objective of minimizing the forces on side objects is the aim of the work pre-sented here. In the first part, we study the possibilities of shape optimization based on a potential flow around a train head for which the train head is modeled by superpos-ing monopole sources on to a homogeneous flow. The aerodynamic load on a sphere induced by the head pressure pulse of a passing train is also calculated using potential flow theory and the results are compared with experimental data which were meas-ured in a moving model rig. Since good agreement with the experimental results is obtained for the pressure pulse induced by the train head, we conclude that the poten-tial flow model is suitable to predict the forces on track side objects generated by the pressure wave. Thus, the simplified potential model is used to optimize the shape of the train head with the objective of decreasing the sucking force on trackside objects. In the second part, we predict the aerodynamics of a passing train numerically by solving the Reynolds-averaged Navier-Stokes (RANS) equations. The focus of this study is to explore how far adjoint-based shape optimization using the continuous approach in conjunction with filtered gradients and CAD-free mesh morphing based on radial basis function interpolation is capable of meeting the requirements of aero-dynamic train design. The results presented considering shape optimization with re-gard to the pressure wave generated in external flows reveal the feasibility and capa-bility of the process chain developed. This part of the paper includes new results of the work started in Jakubek et al.

Modeling and Simulation of Freight Wagon with Special Attention to the Prediction of Track Damage S. Stichel, P.-A. Jönsson, C. Casanueva and S. Hossein Nia Department of Aeronautical and Vehicle Engineering KTH Royal Institute of Technology Stockholm, Sweden Abstract Rail freight traffic usually implies high axle loads that tend to exert high forces on the track. To keep track damage on a reasonable level vehicles have to be optimized with respect to their suspension parameters. Also the wheel rail interaction, i.e. the shape of wheel and rail profiles and the tribological conditions, are very important to limit wheel and rail wear and Rolling Contact Fatigue (RCF). A very helpful tool to investigate the system behavior and to find optimal solutions is multibody simulation. The Royal Institute of Technology (KTH) has long experi-ence in modeling and simulation of the dynamic interaction between vehicle and track, ranging from wagons with single axle running gear with link suspension to iron ore wagons with three-piece bogies and an axle load of 30 tons. Due to that freight vehicles in most cases rely on friction damping which results in strongly non-linear and even non-smooth characteristics it turns out that it is ex-tremely difficult to get satisfying agreement between simulated and measured vehicle reactions. Further the parameters of a friction damper arrangement can vary a lot de-pending on weather conditions, maintenance status etc. The common difficulties that arise will be discussed and solutions proposed. Another focus is the prediction of track damage which here includes both deterio-ration of track geometry and wear and RCF of wheels. Examples from different stud-ies will be shown and the relevance of certain parameters for the level of damage will be demonstrated.

Railway Transitional Zones: A Case History from Ballasted to Ballastless Track S. Costa D’Aguiar1, E. Arlaud1, R. Potvin2, E. Laurans2 and C. Funfschillling1 1SNCF, Innovation & Research Department, France 2SNCF, Engineering Department, France Abstract French high speed line network is in itsmajority composed of ballasted track. None-theless in 2007, a new experimental slab track was constructed in the new East Euro-pean High speed line, from Paris to Strasbourg, operating at 320 km/h. Special transi-tion zones were then designed and constructed in order to provide the correct stiffness transition between the two different structures. The main goal of this paper is to pre-sent the case history regarding the performance of this transition zones after some years of operation. For this purpose an in-situ experimental campaign was carried on track. In addition, numerical simulations were performed in order to provide a deeper insight of the mechanical behavior of track and substructure. As a final application, the present work allowed to define renewal works recommendations for these transi-tion zones from ballast to ballastless track. The paper underlines that the main chal-lenges for an accurate transition zone design is not only to verify the stiffness transi-tions but also to verify the dynamic interaction between train and track and between superstructure and substructure components.

Contact Forces and Running Stability of Railway Vehicles G. Malavasi Department of Civil, Building and Environmental Engineering Sapienza, University of Rome, Italy Abstract Running stability, intended here as stability against derailment, is governed mainly by the magnitude of the contact forces, which are effective only if they are able to pre-vent the wheel lifting from the rail. Contact-force measurement methods are still necessary for the acceptance of the vehicles, especially for those designed for high speeds. However, they are affected by uncertainties in the results which depend on the measurement techniques. In this paper we analyse different measurement systems, both on-board and track-side, and their ability to meet requirements coming from design, operation and main-tenance. We examine measurement principles, advantages and disadvantages of the methods characterized by sensors on the wheel, on the axle and on both or on the rail. In particular, we consider the uncertainties that arise from the position of the wheel-rail contact point, from the effects of speed and temperature on the strain of the wheel and the overall uncertainties reported in the literature by the authors. The quantitative knowledge of the uncertainties can guide manufacturers in the choice of a cost-effective method for use in acceptance testing and can guide research-ers in seeking directions for improvement.

Economic Challenges of Railway Innovations: Model-Based Analysis of Optimized Market Diffusion of Satellite-Based Localization Systems for Train Control Systems R.S. Hosse, K. Burmeister and E. Schnieder Institute for Traffic Safety and Automation Engineering Technische Universität Braunschweig, Germany Abstract Innovations for safety relevant applications in railway always afford a tremendous effort of engineering and business evaluations, since railway technologies are heavily interconnected and embedded. The basic problem of applying traditional business evaluation methodologies for railway innovations is the oversimplification or focus-narrowing. Oftentimes use cases represent the benchmark for all possible applications. Solely whole markets and comprehensive approaches are performed. This contribu-tion shows the methods and findings, which have been applied in the EU projects SATLOC for business evaluations. This project focuses on the application of satellite based train control systems in railways. The performed business evaluations were spe-cifically designed for the projects' designation and the results are based on semi-quantitative analyses and model-based approaches. By doing so for the overall project more generic findings can be found and are not limited to certain applications.
