Competition Sit Ski Final Design Report, Kyle Martinez, Vinay Clauson, Ben Woodward

Mechanical Engineering

This project consisted of designing and fabricating a competition sit ski for an above-knee double-amputee, Andy Soule.  Andy is a talented athlete who won a bronze medal in the 2010 Winter Paralympics.  The project was completed by VinayClauson, Kyle Martinez, and Ben Woodward, mechanical engineering seniors at California Polytechnic State University in San Luis Obispo, CA. The project advisor, Professor Sarah Harding, and sponsor Dr.  Brian Self, of the Mechanical Engineering Department at Cal Poly, oversaw the project with the help of Jon Kreamelmeyer, a former coach of Andy's and a valuable source of knowledge.  The sit ski project was …

Asme Human Powered Vehicle, Benjamin Knaus, Philip Basmadjian, Nick Supat

Mechanical Engineering

Speed Solutions has been contracted to design and build a Human Powered Vehicle (HPV) frame and drivetrain for the Cal Poly HPV club to use in their 2011 race season. This project is being funded by the Cal Poly HPV club and their sponsors. The goal is to design, test and build a bicycle frame that the HPV club can attach to a fairing of their design. Primary design considerations will include speed, weight, cost, rider ergonomics, reliability and ease of repair. This vehicle will be used to compete in ASME’s Human Powered Vehicle Challenge (HPVC) series of races.

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

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.

Tk Ripper, Charles Volk, Vincent Priolo, Zachary Mckibbin

Mechanical Engineering

The TK Ripper was designed to pull a rider on a wakeboard up from a deep water start. We believe the force and power required to pull a rider on a wakeboard out of the water provides enough force and power for many other extreme sports.

Solar Array Suspension Mechanism Final Design Report For Atk Space, Alex Gould, Randon Kruse, Jeremy Graul, Patrick Barney

Mechanical Engineering

The purpose of this project is to improve the existing Solar Array Suspension Mechanism used by ATK Space for the manufacturing and testing of deployable solar arrays. The current system requires too much time to operate and has too many removable parts that may fall and damage the solar arrays. Through the design and verification process the team successfully constructed a quick connecting suspension mechanism that requires no tools to use and has no removable parts. The final design includes the existing force gauge and large adjustment bars used by ATK Space with the addition of a compression spring adjustment …

Formula Sae Interchangeable Independent Rear Suspension Design, Mike Mccune, Daniel Nunes, Mike Patton, Courtney Richardson, Evan Sparer

Mechanical Engineering

The Suspension Solutions design team has completely designed built and tested an independent rear suspension system for the 2008 FSAE car. The car currently features a solid rear axle, and the task of converting it to incorporate an interchangeable rear suspension has been undertaken in order to quantify the advantages and disadvantages of each design philosophy. The car has been properly tested with both the solid axle and independent rear suspension side-by-side, however more testing is suggested. After pushing both setups to their limits on a 50ft diameter skid pad, the test results were quantified, and a final comparison between …

Supermileage Team - Urban Concept Competition Vehicle Chassis Design Report, Andrew Allport, Kevin Braico, Kevin Charles, George Kyi, William Lai

Mechanical Engineering

This research and design project was proposed by the Cal Poly Supermileage team. They have requested for our team to design an Urban Concept car, a new category of vehicles to compete for fuel efficiency in the Shell Eco-marathon in 2010. The primary focus of our team is in the design and construction of a chassis the Supermileage team can use for the 2010 competition in Fontana, CA. This design must meet dimensional and functional requirements set by Shell while being designed to maximize efficiency in the competition.

There were various chassis concepts under consideration that would possibly work for …

Hydraulic Hand Press Final Project Report, Nathaniel Marc Brown, Matthew Thomas Knorr

Mechanical Engineering

This report provides a thorough description of the design of a hydraulic hand-operated press by mechanical engineering students at California Polytechnic State University, San Luis Obispo, California, for the Estrella Warbirds Museum in Paso Robles, California. It begins with research into hydraulic operations, a brief study of fluid power and incompressible fluids, and a look into existing products.

Brainstorming and decision matrices are utilized as well, conveying our design process. A basic structure is developed using strength …

Best-In-Class Global Bumper Reinforcement Beam, Garret Anthony Bautista, Chad Anthony Hardin, Benjamin Ray Taylor

Mechanical Engineering

Modern bumper systems are governed by laws and regulations imposed separately by various countries. Today, the regulations in China, North America, and Europe are becoming more similar, but there is not a widely accepted bumper reinforcement that meets the requirements of all markets around the globe.

A universal bumper reinforcement beam incorporating Plug-n-Play techniques was developed to meet and exceed all testing requirements and performance standards of each country. These Plug-n-Play techniques consist of adding energy absorbing attachments to the front of a base bumper beam. Simple beam analysis and FEA were the primary analysis tools in the development of …
