Jcati Carbon Fiber Recycler: Crusher System, Devin Riley
Jcati Carbon Fiber Recycler: Crusher System, Devin Riley
All Undergraduate Projects
With a substantial rise in Carbon Fiber use across all industries, the need for a way to recycle the waste has grown as well. A group of Mechanical Engineering Technology students at Central Washington University funded by the Joint Center for Aerospace Technology (JCATI) have created a machine to recycle waste wing trimmings from the Boeing company’s airplanes. This machine consists of 5 different sub-assemblies being the oven, crusher, gear train, conveyor, and shredder. The purpose of this project was to decrease the deflection in the crusher caused by bulging in the housing and movement of the bearings. To decrease …

Hydraulic Balsa Wood Rising Bridge, Kaitlyn Greenfield
All Undergraduate Projects
What is the solution to allowing tall vessels to navigate past a vehicle bridge that is less than 10 [ft] above the water? To answer this question, a balsa wood bridge was designed, constructed, and tested. The bridge needed to articulate by mechanical means, allow for travel through the bridge, and be able to withstand ample force while the main structure only being constructed of balsa wood and glue. The project was analyzed in sections. These sections include: the bridge structure and its members, the hydraulic lift, and the pins needed for the bridge and hydraulic lift to operate. The …

This objective of this project was to design, manufacture, and test the mechanical systems of an electronically-controlled continuously variable transmission (eCVT) for the Cal Poly Baja SAE vehicle.
Fatigue Tester, Nicholas Fazio
Fatigue Tester, Nicholas Fazio
Williams Honors College, Honors Research Projects
The purpose of this project is to combine all my experience, knowledge and skills that I’ve acquired over the years as a Mechanical Engineering Technology student to completely design and build a fatigue tester. This will give me valuable experience in the process of designing and assembling a product and give me a great example to add to my portfolio. The tester will be completed through a process of researching design and modeling. Once everything is properly calculated and designed the parts that can be fabricated will. The rest will be ordered and then everything will be assembled. Upon completion, …

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 …
Design Of A Robotic Cownose Ray, Mark Marzotto
Design Of A Robotic Cownose Ray, Mark Marzotto
Honors Theses
Nature often inspires advances in science and technology and a promising example of this is mimicking locomotion of underwater animals. The main ways in which manmade aquatic vehicles propel themselves are water jets and propellers, which are inconsistent with how underwater animals swim. The cownose ray displays very efficient thrust with low frequency strokes by using a combination of oscillations and undulations with its pectoral fins. The goal of this paper is to mechanically replicate the actual fin motion of the cownose ray in order to capture these attractive features. The design will account for both the oscillations by designing …

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.

Universal Play Frame Vi, Justin Bazant, Cullen Crackel, Anthony Franceschi
Mechanical Engineering
This design report details the design process utilized by Adaptive Exercise Designs (AED) in creating the sixth design of the Universal Play Frame (UPF). The UPF is an adaptive frame which supports a variety of devices that allows athletes in wheelchairs with limited range of motion to participate in physical activity. The past five frame designs do not meet the needs of the Friday Club due to complications with function and time constraints. To ensure all of Fridays Club's needs were met, the problem was better defined by converting the customer requirements into engineering specifications. The design process our team …
Sae Baja: Final Drive Gearbox, Michael Mccausland, Michael Watkins, Ian Masterson, Andrew Sommer
Sae Baja: Final Drive Gearbox, Michael Mccausland, Michael Watkins, Ian Masterson, Andrew Sommer
Mechanical Engineering
This paper presents the results of a manual transmission project for SAE Baja. A full engineering process is documented, including problem definition, scheduling, conceptualization, decision theory, synthesis, analysis, manufacturing, and testing. A comparison is made between existing and potential mechanical power train solutions. The final design is analyzed in dynamic simulations, AGMA stress, predicted FFT spectrums, and shifting rod buckling. A number of complicated parts are manufactured through investment casting and direct CNC machining. Issues in the final assembly have prevented the project from being fully realized, recommendations are made for future SAE Baja teams.
