Modal and Stress Analysis of Lower Wishbone Arm Along

with Topology Optimization

Pratik S. Awati*, L. M. Jugulkar

Department of Automobile Engineering, RIT, Rajaramnagar, Maharashtra, India

Abstract An independent suspension allows wheels to rise and fall on their own without affecting

the opposite wheel. The aim of study is to complete FEM analysis of a suspension link for deformation and stresses in dynamic mode. For this a 3-D solid model of a suspension

link is generated. Multi body system approach is used to determine the loads acting on

the suspension component. Vonmises Stress analysis is to be done by considering Gross Vehicle weight with application of forces on Lower control arm. This gives an idea of

optimization area by providing an extra material in the region where the control arm is fixed to the chassis body. The effect of different material on the yield stress value is

studded to find out the suitable one for manufacturing purpose.

Selection of R14-tyres using Analytic Hierarchical

Process on the Basis of Uniformity and Strength

Amrita Singh*, Sharad Agrawal, Dinesh Kumar Kasdekar, Chandra Shekhar Malvi Department of Mechanical Engineering, Madhav Institute of Technology & Science,

Gwalior (M.P), India

Abstract Tyres play a commanding role in an automobile industry. Balancing and safety of the vehicle are the primary issues for automobile industry. These two parameters are highly

dependent on the uniformity and strength of the tyres. There are various criteria that

affect tyres uniformity and strength. Consequently, selection of tyres is a Multi-criteria Decision Making (MCDM) problem. In that respect are many methods available for

selection of tyres; however, this paper targets to explore the applicability of AHP

(Analytic Hierarchical Process) to solve R14-tyre selection problem. AHP is a method that assists in choosing best alternatives by pair-wise comparison of each alternative and

their criteria expressed as a matrix. In this work, synthesized priority of the R14-tyres and organize priorities of the R14-tyres with respect to each criteria in matrix is presented.

After that, each column of the alternatives is multiplied as per the priority of the

corresponding criteria and finally the ranks are evaluated by adding each row. The pair-wise comparisons are made with the standard scale, on the basis of given criteria, which

conclude how much one alternative is more important than other. Uniformity and

strength parameters have been discussed and it concludes with the selection of R14-tyres on the basis of this methodology.
