Shoe Tread Analysis

For my final FEA report, I was to run an analysis on something of my choosing. Due to my desire for wanting to go into the shoe industry and run FEA studies to make shoes better, I felt that this was a perfect time to get my feet wet doing just that.

For this analysis, I looked at four different tread patterns and sought to learn which would deflect the least, which in my mind, meant that the shoe provided more grip when a basketball player was moving around on the court.

Through this attempt, I felt like I learned a lot. Initially, I thought that modeling the shoe tread and the forces that are present on them would be easy, however, that assumption was wrong. Determining how much force and how the force was applied turned out to be more difficult than I initially expected. Also, during the analysis, I tried to simplify the treads down so that I didn’t need to model as many. While this was effective in saving time, I am concerned that it has therefore invalidated the analysis. Further research and talking with industry professionals would be required to better understand if my analysis is valid or not.

Rod Spring Back Analysis

After wrapping a rod around a mandrel there will inevitably be some amount of spring back that happens. In this study, I sought to use FEA to predict the spring back of aluminum rods after they had been wrapped around a circular mandrel.

Centrifugal Clutch Study

For this analysis, I was asked to calculate the deflection of the arm of a centrifugal clutch based on angular rotation. To do so, I developed equations to calculate the deflection of the clutch as a function of the rotational speed.

Within the FEA model, parts of the clutch model were cut away to make the analysis simpler. Which parts were cutaway is shown on the first page of the report.

FEA Efficiency Study Regarding Large Deflections

For this report, I was asked to simulate a 3D printed PLA cantilever beam that is 150 mm long with a cross-section of 1mm x 10 mm. At the end of the beam, a transverse end load at a range of force magnitudes would be present. I was then to compare the predicted deflection to the linear and nonlinear FEA analysis. Below is the report that I wrote up after completing the analysis.

Mechanical System Design Applications and Learning About Finite Element Analysis

In my final semester of college, I am looking forward to taking a class that I have been excited about for over a year now. It is a class that goes further in-depth learning about mechanical system design, as can be inferred by the name, and also builds upon the knowledge of finite element analysis that we obtained in a previous class that is required at BYU. Over the course of the semester, we will write reports regarding the analysis that we perform and what is learned through doing it. This will culminate with a final project performed as we analyze something of our choosing. While I work on these and submit them, I will post them here to show examples of the work that I am able to do!

No Pain With All the Gain

Many have had the unfortunate experience of trying to pick out their morning toast and consequently burning their fingers on the toaster because their toast isn’t tall enough or the toaster doesn’t bring it up high enough for there to be enough room to grab their toast. That is where this design for a new toaster comes in. As part of my product design class, I spent time creating a conceptual design for a new toaster that would be wide enough for pieces like homemade bread and bagels to fit into the toaster without issue and the basket would rise high enough that even your small slices of toast can be brought high enough to grab.

Since this design was mostly conceptual, iteration was through multiple drawings. Those drawings as well as pictures of my final design can be found in the report below.

The StakCrate Photography Carrying System

For my product design class, we had a group project as our final. We had a variety of different groups of people that we could try to help out via a new design, and we chose to help photographers. Very frequently, photographers regardless of if they do their shoots out in nature or in a studio, have a lot of equipment that they need to carry. We got this information through interviews that we conducted with acquaintances that we had who were photographers. A wide range of experience and skill was represented through the different photographers we interviewed. Many talked about how safe transportation of their equipment was a major worry. Some have a dolly that they load up and they try to not drop anything as they transport it. This can be very dangerous, and if something does fall and break, it can be very costly to replace. Others just enlist friends and they all carry the necessary equipment. We heard frequently that Pelican cases were the best, but they were also very expensive. Our team decided that we wanted to come up with a new offering for photographers to transport their equipment that would be better than the Pelican Cases.

Once we decided what we wanted to make, as well as our goal, we began to come up with design ideas that we drew on 3″x5″ cards. Before we started putting any of these designs together, we had come up with over 150 different features we could put into the design. As we whittled down the features that we felt would best help our imaginary clients, we took inspiration from pack-out systems made by DeWalt and Milwaukee.

Due to this, we made it so that each case would have the ability to be wheeled around like a suitcase, but if you had multiple, you could stack them and wheel them around like an appliance dolly, with that configuration shown in the picture below.

We also made a physical prototype of our design and were able to get some feedback from others regarding it. They liked that there were different ways to roll the case. They did worry about the handle used to roll the case staying in place but were generally positive regarding the design.

Below you can see our final presentation as well as our report which contains more information on this project.
