2-Dimensional Fowler Flap Simulation

My project will involve the 2-dimentional simulation of a Fowler flap, a high-lift trailing edge device used in most common commercial aircraft today. I will be working towards this effort alone. The project will be completed using Matlab, and I hope to be able to show an animation of the flap extending and retracting by the terminus of the project. Due to the project being simulation-only, I will likely need no physical resources, but will need to learn about mechanical simulation and animation methods in Matlab. If I am unable to perform a solid animation in Matlab, I will attempt to do so in Python. As a graduate student in aerospace engineering, I feel this project is both relevant to my personal interests and my professional development as an engineering because it allows me to understand and contextualize the design decisions that go into aircraft systems such as flaps.

TITLE: Study of the kinetic forces and kinematic motion of the human arm when cranking on a Tuna Fishing Reel This study intends to simulate and calculate the kinetic forces on human arm joints as well as the kinematic motion of the appendages within the arm. This project is intended to be approached first in theoretical equation formulation with matlab and then simulated with computer programs such as solidworks or Unigraphics. I intend to complete the study individually and need no special resources for this study, as I already have equipment that is similar to tuna fishing gear. My personal purpose of this study is to improve my fishing technique when fishing for the pelagic fish of the ocean. These fish, when fought without strategy, can wear and literally tear human ligaments and muscles in fights that can last 1 to even 5 hrs. A better understanding of the best position and motion to reduce unnecessary strain to the body will greatly help my and others ability to appropriately fight these strong fish.

3-Point Hitch Draft Control

Travis Bills will be working alone on this project. There will not be any expenses for this project,

since it will be simulation only. This is important, because draft control makes plowing a field easier for

the operator. This system can operate in two ways. For the first use, the operator can set the plow to

follow the contour of a field with an uneven terrain to maintain a depth that is nearly constant. For the

second use, the operator can set the system to maintain a constant load, so that the plow depth will

either increase or decrease based on the field conditions. This allows the operator to maintain a

constant velocity without having to worry about stalling the tractor, while at the same time, achieving

the maximum depth for the given velocity. I would like to simulate the kinematics/dynamics of this

system using MATLAB for varying terrains and field conditions.

TITLE: Kinematic Backyard Picnic System WHO: Dailen Brown HOW: Rapid Prototyping for final result, hand fabrication and simulation for design WHAT: Minimal expenses as I have a 3D printer and material in stock at home, may decide to use other processes instead which could add to cost. WHY: My wife, 2 daughters, and I have a tradition of eating a picnic outside in our backyard every Sunday during the summer. My wife loves porch swings/swinging benches and we don’t have one. For this project I will be designing and rapid prototyping a scale model of a Kinematic Backyard Picnic System which will be a picnic table with attached benches that will convert into a single swinging bench using kinematic linkage mechanisms. I had the idea for a project of this type 2 summers ago while my wife and I sat and had our Sunday afternoon picnic. We wanted to have a picnic table eventually, and I knew my wife really enjoyed swinging porch benches. The challenge in this system will be in the creation of a mechanism that will allow for a stationary table with attached stationary benches to convert easily into a single swinging or rocking bench without the need to remove/separate any parts. Due to time and financial constraints, I will be designing the mechanism and rapid prototyping a working scale model of the picnic system this semester with plans to construct a full scale finalized system at a later date. Here is a rough simple mechanism prototype for converting a table to a bench that I created out of K’NEX last weekend. Pictures:

Project Prospectus – ONE PARAGRAPH Delray Canfield

My proposed final project is 3D modeling and construction of a spherical 4 bar mechanism. I

would use plastic FDM printed parts for the primary components with any other hardware as needed. I

would do this project individually.

Project Proposal: Sean Commet

For my project, I would be interested in doing some 3D modeling of a my cars’s suspension.

Since we have not performed any 3D modeling in this class, I don’t yet know how big the scope of the

project should be. I am currently trying to fix up a Pontiac Fiero in my free time, and I think that it would

be very interesting to perform some suspension modelling on it. They made some interesting

suspension choice to cut costs and I want to see if I can see the impact of those choices in the modeling.

Hopefully I will be able to more easily define the scope of my project once we perform some 3D

modeling in class.

Custom Treadle Pottery Wheel

I intend to design and construct a treadle pottery wheel. I will begin from the Simon Leach style assembly (shown above), but customize it for easier manufacturability (with the tools I have on hand) and portability (for the space I currently live in). I’m sure it won’t be the quality of the photo above, but it should still do the trick! The treadle is a perfect example of a four bar mechanism with input rocker (kick pedal) and output crank (inertial disk).

Title: Dynamic Analysis of Jumping Human

I will work alone. I would like to digitize a jumping video from youtube to find out the motion of feet,

ankle, knee and hip during the jump. Then I’ll conduct kinematic and dynamic analysis while estimating

the mass and centroids. Also I’ll try to find out how much force is needed on the front of the feet to lift

the whole body from the ground assuming the weight of the body. No simulation or hand fabrication

will be needed, thus there will be no associated cost. Mechanics of human body always amuses me,

that’s why I am planning this project.

ME 581 Mohammed Mohammed El Husaini

Project Prospectus

I will be attempting to model a human ankle using additive manufacturing. I will first research the mechanism(s) that enable the ankle to rotate. After researching, I will attempt to model the ankle in SolidWorks in order to build a model that can be 3D printed. I will most likely have issues getting the model to rotate properly because 3D printers have issues with curves, so I will also need to research how to mitigate that problem. My model won’t be the most accurate representation of the ankle, but the model will be able to demonstrate proper rotations. No motors will be used, I will use my hand to rotate the model in different directions.

Kyle Niemeyer

Project Proposal

ME 581

Who:

Kyle Niemeyer. I am working alone.

What:

I would like to build a 3D spherical four-bar mechanism. I will design it according to the principles that

apply to four bars that operate in the spherical coordinate system, and I will 3D print the parts that are

required to make it.

Source: https://www.europeana.eu/portal/en/record/2020801/dmglib_handler_image_16236023.html

Why:

While I have seen many four bar mechanisms, I have had no experience with spherical mechanisms in

the past. This project will lead me to learn the concepts that go into designing a spherical four bar

mechanism. It will also allow me the opportunity to build one.

How much:

$0. The ME Department does free 3D printing for ME class projects.

MATLAB + CAD SIMULATIONS ON A SPHERICAL FOUR BAR MECHANISM

Use the potential of Matlab and CAD systems to develop a process for mechanism simulation

with more reality. The project will use a spherical four bar mechanism as the main prototype for testing

and small examples to verify the responsiveness of the process. Rapid prototyping is desired for analysis

purposes.

ME 581 Final Project Prospectus John Sherbondy

My project idea is to construct a little design for four bar mechanisms with special geometry that

gives them mobility. Specifically, my project title would be “Spherical Four Bar” showing how a

spherical four bar moves compared to a planar four bar. I do not have plans to work with anyone on this

project. This project will be constructed from rapid prototyping the links of the mechanism and machining

the sheet metal base that will also hold a basic DC motor circuit to drive the mechanism. With some very

basic research on the cost of components, I do not expect so spend more than $50 on this project,

although I am not familiar with the cost of the good 3D printers on campus. I also plan to do some basic

3D analysis of this mechanism with matrix techniques when we get to that portion of the class. I chose

this project because I did a much more analytical project in ME 481, and wanted to try a more fabrication-

based project to apply some of the concepts that we have been using in real (or real-er) life.

Sir,

I intend on doing my final design project on the analysis of the double wishbone suspension. Each

wishbone is connected to the chassis by two revolute joints and connected to the wheel via a spherical

ball joint to the knuckle. These suspensions are often seen in high performance vehicles like an Formula

One car. COMSUBPAC has a 3-D printing facility where I can create the joint. I think I’ll be able to model

the vertical direction, as when a car goes over a bump via Matlab.

Cody Wassel ME 581 Project Prospectus

For the final project, I’d like to focus on Whitworth quick-return mechanism as found on a

shaper machine (see image below). I plan on manufacturing a model of such a mechanism out of steel

and aluminum. I would order the raw materials, and fabricate the components via mill/lathe and

possibly waterjet.

I particularly like shapers because of their mechanical beauty. As far as I know, they’re slowly

fading out of industry, as they’re being replaced by hydraulic-powered shapers. Nonetheless, shapers

are still a more accurate option than a mill for making dovetails, and a more versatile means of making

keyways than using broaches on an arbor press.
