Parametric Design Of Flywheel For An Electric Punch Press, Prashant Dhakal
Parametric Design Of Flywheel For An Electric Punch Press, Prashant Dhakal
Honors Theses
Almost all designs start with a design requirement. These may be weight, volume, clearance, and even custom calculations. Finding a solution that meets these requirements often involves tedious and time-consuming iterations. Once the solution has been found, the design must be optimized to find the best possible solution. Finding the ‘best possible design’ requires substantial time and effort dedicated to iterating and analyzing the potential model solutions. This is where Parametric design comes into play. The Parametric design aids in specifying the key parameters of the design and makes changes interactively, with the model updating automatically. The purpose of this …
Hydraulic Balsa Wood Rising Bridge, Kaitlyn Greenfield
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 …
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, …

Adapted Pool Cue, Cole Clark, Daniel Patterson, Michelle Cheung, Dylan Sauer
Mechanical Engineering
Our primary goal was to develop an adaptive device to allow a user with limited upper body mobility to more effectively play a game of pool. Within this goal it was important to design around the concept of a least restrictive environment, in order to provide the user with as close to a standard pool playing experience as possible. The device was designed to specifically meet the needs of John Lee, an Assistive Technology Specialist at Cal Poly's Disability Resource Center. Mr. Lee has muscular dystrophy, which limits his upper and lower body mobility and currently requires his use of …
Senior Project #7: Longboard Test Apparatus, Derek Chan, Colin Harris, Nico Lee
Senior Project #7: Longboard Test Apparatus, Derek Chan, Colin Harris, Nico Lee
Mechanical Engineering
The aim of this project is to create a machine that will test longboards made by Method Sports and Freebord. Through analysis and many iterations, Board Busters has assembled a design to fulfill the requirements set forth by these companies, who also sponsor the project. Through use of a four-bar, frame, and two spinning disks, the machine will accurately simulate riding conditions seen by a board in use by customers, allowing the sponsoring companies to improve designs and verify warranties.
Historic Calculator Project, Will Harris, Dan Marioni, Kevin Webb, Chad Williams
Historic Calculator Project, Will Harris, Dan Marioni, Kevin Webb, Chad Williams
Mechanical Engineering
The Deutsches Museum of Munich, Germany requested add-on components to their mechanical calculator exhibit. The end-goal is to produce an interactive 3D model in software to demonstrate the functions of the Braun-Vayringe Machine (BVM). There will be four students working on this project at California Polytechnic State University, San Luis Obispo: two mechanical engineers (Dan Marioni and Will Harris) and two computer engineers (Chad Williams and Kevin Webb).This project involves the coordination of three facilities; the Deutsches Museum, and the Mechanical and Computer Science Departments of Cal Poly. The name of the project is known as the Historic Calculator Project …

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.
