Boat-Lift Design And Analysis, Nathan Schick

Honors Theses

A current in production 6000 lb. rated boat-lift is being sold at “Great Lake Lifts”. The lift was tested experimentally and proved to hold at least 8000 lb. The design team successfully modeled the current lift on Ansys to help the customer understand where the weakest points in the design were. Following the creation of the initial lift design, the design team proposed and tested modifications that could be made in order to make the lift more structurally sound. The initial lift had a maximum deflection of 0.43846 inches, a maximum stress of 15880 psi, and a safety factor of …

Low-Cost Control Engineering Experiments, Megan Arduin

Honors Theses

The disciplines found within the area of motion and controls is a vital element of each engineer’s education. The ability to understand and then control dynamic systems is a fundamental skill required for many working engineers today. The aim of this project is to further develop the tools and methods available to teach and prepare engineering students to effectively design control system architecture, and then successfully implement their design into real world systems. The main goal is to design an apparatus that can be used to teach control system methods and has an affordable price. There are few experiments where …

A Comparative Analysis Of Professional Pilot Jobs, Ryan Snoeyink

Honors Theses

Professional Pilots fly aircraft for a living. Just like there are many different types of aircraft, there are many different types of professional pilot jobs. While it is an impossible task to describe every single job a professional pilot could have, there are four "groups" in which most jobs can be classified. These groups are Part 121 Scheduled Airline Service, Part 135 On-demand Charter, Part 91 Corporate/Private, and Part 61/141/142 Flight Instruction. The goal of this thesis is to examine the differences between these four groups; and by doing so, aid in the education and career decision making of those …

Design Of A Cubesat Separation Mechanism, Ross Hiller

Honors Theses

CubeSats are compact, relatively inexpensive satellites that are often used for space research. In order to perform research related to electric propulsion devices, the Western Aerospace Launch Initiative (WALI) requires a medium-sized CubeSat capable of separating into two bodies while in orbit. Intentional separation is not common in CubeSats, so two original concepts were designed and simulated using 3D CAD and finite element analysis software. These designs were compared based on factors including weight, cost, size, and their potential to fail due to creation of debris or binding between components, in order to determine which will more effectively execute the …

Reprinter, Christian Brower

Honors Theses

Additive manufacturing (3D printing) is a rapidly growing technology, though, expensive printing filament and wasted material make it less affordable and an unsustainable process. The RePrinter combats these issues by recycling scrap 3D printed plastic parts and household plastics, such as pop bottles, and creates filament for fused deposition modeling (FDM). This product is a fully automated system which grinds, extrudes, and spools the filament for immediate use in FDM. The RePrinter works to control the extrusion speeds and tensions to optimize precise filament dimensions for quality 3D printing, while delivering the product in a timely cost effective manner.

Torsion Element Test Bench Design, Trevor Gick

Honors Theses

A test apparatus has been designed to apply a torque to a range of suspension products developed and sold by ROSTA USA Corporation (ROSTA). The products tested here are used in industrial applications, including vibration damping and suspension for industrial machines.

The designed device takes several specifications into account. To withstand the forces applied to it, the structure of this device is created from steel with bracings to support heavily loaded areas. The device is designed with a “sled” type design so that a forklift will be able to move the sled if needed. To apply torque to the elements, …

Biogas Separator And Storage Tank, Brandon Nimtz

Honors Theses

The general concept of this project is to design, simulate, and build a biogas separator system that will also store the separated methane and carbon dioxide within pressure vessels. This system is constructed of many subcomponents that will combine to separate the biogas and store the methane (CH4) and carbon dioxide (CO2). The components included in the project consist of a liquid-gas separator vessel, two heat exchangers, one methane gas compressor, and one pressure vessel each to hold methane and carbon dioxide each. While the base goal in this project was to design and simulate the necessary parts to theoretically …

Sensory Interfaces: Intelligent Surgical Box Trainer, Krystal York

Honors Theses

The Fundamentals of Laparoscopic Surgery (FLS) box trainer currently offers medical students the opportunity to practice their dexterity with laparoscopic surgical tools and accustom themselves to the disconnect between their actions and their visible frame of reference. However, at this stage the box trainer offers few ways to test, practice, or improve upon important factors in laparoscopic surgery including disturbance of and pressure applied to patient tissue. The purpose of this project was to add sensory interfaces to the FLS box trainer to offer more concrete feedback for medical students practicing the required tasks, consolidate the information gathered by the …

Ceas Student Center Expansion, Turner Solterman

Honors Theses

Western Michigan University has had a long-standing tradition of engineering excellence. To keep up with the modern culture and to maintain that Western will be on the forefront of universities providing an excellent engineering education, an expansion to the current CEAS building on the Parkview campus is necessary. Aptly named the CEAS Student Center Expansion, this project will be a space exclusively for student engineering groups to work in a space where collaboration across different engineering disciplines will be as easy as walking across the floor to talk to someone else. Through the floor plans of the different alternatives …
