Heat Transfer Experiment: Energy Conservation, Ben Ward, Brett Wallace, Ryan Waltman

Mechanical Engineering

This proposal, prepared for the Mechanical Engineering Department by the HTEC design team will redesign and replace the current energy conversion lab that is inaccurate and out of date. The team will evaluate methods of energy conversion, specifically using braking systems, as well as existing labs in order to design an accurate and relatable experiment for this lab. The project team will work with Professor Kim Shollenberger in order to design an experiment that demonstrates energy conversion through the first law of thermodynamics while utilizing a common device that is practical in student’s lives. The final result of this project …

Exploration Station Kidshake Table, Jeremy Duhe, Philip Hopkins, Matt Ostiguy, Samantha Weiner

Mechanical Engineering

The KIDShake Table is an all mechanical earthquake shake table sponsored by the Exploration Station Children's Museum of Grover Beach. This interactive exhibit has two working mechanisms, a hand crank and pull rope, that provide two axis movement for knocking down block structures. This table was built and designed for a target age of 10 years.

Mechanical Engineering

In recent years, the cycling industry has witnessed huge advancements in bicycle components and materials. The age old goals of speed and low weight are still present today, but the pursuit of these goals may be reducing the structural stability of various components integral to wheel performance, including the wheel hub bearings. These bearings are invaluable to bicycles but little is known about how the forces and loads applied to a bicycle affect the performance of these bearings. Broken axles and hubs are indicators of significant stresses within the hub, but little is known about how the resulting deformation affects …

Dedion Axle Senior Project, Nick Schraan, Mark Shushnar, William Swenson, Ramy Tall

Mechanical Engineering

The sponsor, EV Grid Inc. is a company looking to the future with the development of a vehicle to grid infrastructure. The vehicle in development is a Ford E-250 Van which had been converted to electric drive with a front motor, rear drive layout. The sponsor wanted to move the electric motor to the rear and develop an axle to support this change. By eliminating the driveshaft, a more efficient use of battery space could be utilized. The goal of this project is to design and fabricate a prototype deDion rear axle which incorporates a system of drive components that …

Rapid Decompression Containment System, Evan Domingue, Michelle Rudney, Daniel Trees

Mechanical Engineering

Cal Poly students; Evan Domingue, Michelle Rudney and Daniel Trees; are working with General Atomics Aeronautical Systems, Inc. (GA, ASI) and engineer John Wilcox to complete a senior project. The senior project is focused on finding a solution to meet the requirement set forth in MIL-HDBK 1791 4.2.5.2 for rapid decompression which requires cargo items to be designed with pressure relief devices or to be configured for air shipment as to prevent any part from becoming a projectile in the event of catastrophic loss of aircraft cabin pressure. The goal of this project is to design a safe, cost-effective, and …

Rebounder Fatigue Test Machine, Caroline Reeves, Will Robertson, Ethan Flory

Mechanical Engineering

JumpSport, a company that designs and sells trampolines and trampoline accessories, has sponsored this senior project team to design, build, and test a trampoline fatigue test machine. The machine must simulate a person jumping on the trampoline to test the life of JumpSport’s fitness trampolines and kids’ trampolines. Partway through the design process, the objectives were altered and this senior project team was tasked with merging with another Cal Poly senior project group to create an all-inclusive test machine to accommodate both full-trampoline testing and individual bungee cord testing.

The final design is centered on a slider crank linkage driven …
