Adapted Trailer Hitching System, Joseph Neil Hearn, Maxwell M. Selna, Maximilian D. Cossalter, Eric B. Ringsrud

Mechanical Engineering

This report highlights the entire design process of an adapted trailer hitching system for Taylor Morris: a navy veteran and quadruple amputee. This begins with problem definition through customer and product research. Objectives are generated after the problem is defined and the boundary of the project is set. This outcome of the project focuses on modifications/improvements to the vehicle side of the problem and leaves the trailers untouched. Engineering specifications are developed to constrain the concept design direction, which ultimately dictates the outcome of the final design. The final design is used as a basis to manufacture a structural prototype …

Final Design Report For Human Powered Vehicle Drivetrain Project, Derek Fromm, Luke Opitz, Michael Juri, Olivier Côté

Mechanical Engineering

The Cal Poly Human Powered Vehicle Club is building a bike to surpass 61.3 mph in 2019. The club and their mentor, George Leone, have proposed a senior project to design, build, and test the drivetrain for this year’s human powered vehicle. Research into human powered vehicles and their drivetrains has shown that the power that a rider can output and the efficiency at which the rider can pedal depend extensively on the design of the drivetrain. Despite the existence of standard bicycle drivetrain designs, the senior project team has found that the best design to meet the club’s requirements …

Investigation Of Design, Manufacture, Analysis, And Test Of A Composite Connecting Rod Under Compression, Thomas Juhl Rohrbach

Master's Theses

Composite materials hold great potential for the replacement of traditional materials in machines utilized on a daily basis. One such example is within an engine block assembly where massive components inherently reduce the efficiency of the system they constitute. By replacing metal elements such as connecting rods, cylinder caps, or a crank shaft with composite alternatives, a significant increase in performance may be achieved with respect to mechanical strength, thermal stability, and durability, while also reducing mass. Exploration of this technology applied to a connecting rod geometry was investigated through a combination of process development, manufacturing, numerical analysis and testing. …

Stair Climbing Hand Truck, James Mcpherson

All Undergraduate Projects

Abstract

Getting a heavy object up a flight of stairs usually requires a team of two or more people. Even with a team of people, the task is often still difficult, dangerous, and possibly insurmountable by one person. This problem is especially prevalent in for those who are moving into apartment complexes. Most apartment complexes have many buildings with two or more floors of living quarters, and elevators are often missing. This project sought to offer a solution to this problem. The solution in question; a motorized hand-truck with 2, trigonal planar pinwheels in place of the stock wheels. The …

Custom Designed Wall Mounted Shop Crane, Bradley Lewis

All Undergraduate Projects

The objective of this project was to design and fabricate a custom wall mounted jib crane to specific, non-standard dimensions. The crane was designed to be industry rated for 2000 pounds, rotate at least 180 degrees, and be designed to have a maximum boom length tailored to the specific installation site. Two potential installation sites and purposes were selected for construction: inside the bay doors of a fabrication shop, intended to transfer large pieces of material to and from a plasma table, and inside a car maintenance garage, intended to lift and remove engines and transmissions from cars.

Ares Cleaning System, Andy Sagers, John Cunningham, Peter Greig, Jack Glynn

Mechanical Engineering

In this Final Design Review, the team outlines the general scope of the ARES Cleaning System project and the final design direction chosen and built. This team consists of a group of four mechanical engineering students who have been tasked with designing and manufacturing an autonomous ARES cleaning system to help their sponsor, Fracsun, better track soiling losses measured at large solar arrays. They designed, conceptualized, manufactured, and tested throughout the project as they looked to create a final, functioning product. In creating this Final Design Review, they have identified how the product will perform the desired functions and what …

Autojack - Hydraulic Powertrain System, Tyce Vu

All Undergraduate Projects

A primary problem for mechanics and automotive enthusiasts is the risk associated with lifting and securing a vehicle with conventional jack stands. Often times, improper jack-stand installation results in the vehicle collapsing unexpectedly, causing injury and/or death. This problem can be minimized through the application of a newly re-designed vehicle lifting system. The conventional method for lifting cars is time consuming and can be unsafe in many circumstances. A better, safer, and more efficient lift design was needed; the AutoJack. The approach of the AutoJack design was entirely focused on the safety of lifting a vehicle. Safety was improved by …

Enhanced Surface Integrity With Thermally Stable Residual Stress Fields And Nanostructures In Cryogenic Processing Of Titanium Alloy Ti-6al-4v, James R. Caudill

Theses and Dissertations--Mechanical Engineering

Burnishing is a chipless finishing process used to improve surface integrity by severe plastic deformation (SPD) of surface asperities. As surface integrity in large measure defines the functional performance and fatigue life of aerospace alloys, burnishing is thus a means of increasing the fatigue life of critical components, such as turbine and compressor blades in gas turbine engines. Therefore, the primary objective of this dissertation is to characterize the burnishing-induced surface integrity of Ti-6Al-4V alloy in terms of the implemented processing parameters. As the impact of cooling mechanisms on surface integrity from SPD processing is largely unexplored, a particular emphasis …

Reactive Archey Target Design Team "Mimic", Brandon Croyle, Jacob Boss, David Rodgers, Austin Wivell

Williams Honors College, Honors Research Projects

This design project will aim to provide archery hunters with a platform to simulate shooting at string jumping deer. String jumping refers to a spooked deer hearing the snap of a bow string and instintivly ducking up to ten inches. This often results in wounded or missed deer. We will design and build a control system that uses the sound of a bow string as a trigger to operate a mechanical target system. A sound sensor will mimic a deer’s hearing in close range hunting and then send a signal to the mechanical system to replicate the dropping motion of …

Recumbent Bicycle Balancing Aid, James Hager

Williams Honors College, Honors Research Projects

For our senior design project, our team will be consulting to create a balancing aid system intended for the recumbent bicycle shown below in Figure 1. The owner of the bicycle is Robert Henderson, a former United States Navy sailor from Northeast Ohio who picked up biking and skiing while he was stationed in Maine in the late 80’s. While there, he took to the mountains on the rugged terrain and brought this passion of biking back home to share with his wife, Johanna once he completed his service to his country. Biking became an integral part of the …
