Investigation Of The Under-Body Flow Field Of A Prototype Long-Range Electric Vehicle, Matthew P. Nguyen Sep 2019

Investigation Of The Under-Body Flow Field Of A Prototype Long-Range Electric Vehicle, Matthew P. Nguyen

Master's Theses and Project Reports

This thesis presents changes to the design of the Prototype Vehicles Laboratory (PROVE Lab) Endurance Car, an electric car intended to break the Guinness World Record for the single-charge range of an electric vehicle. The design range is 1609.34 km, however at the design velocity of 104.6 kph, the drag is 196 N; which requires more battery capacity than the 100 kWh maximum of the baseline model. With a fixed frontal area, drag reduction can come from lowered velocity or reduced CD. CD reduction is attempted in four ways: side skirts between the fenders, a raised ride height ...


Journeyman International - Rubagabaga Evc And Ace - Rwanda, Africa, Jake M. Stom Jun 2019

Journeyman International - Rubagabaga Evc And Ace - Rwanda, Africa, Jake M. Stom

Construction Management

Rubagabaga EVC and ACE, or Empowering Villages Center and Agricultural Center of Excellence, is an interdisciplinary project based senior project completed by California Polytechnic State University, San Luis Obispo students. College of Architecture and Environmental Design students Jake Stom, Mackenzie Diaz, Julia De Hart, and Jenna Williams completed the design and preconstruction services with the help of non-profit humanitarian organization, Journeyman International. The deliverable aims to serve the client, Empowering Villages, by providing the complete design of a community center and agricultural training facility near Kaseke Village in Rwanda. The goal is to provide the local community with development efforts ...


The Theia Soteria: Alternative Design For Safer Initial Entry During Laparoscopic Procedures, Kayla Dubois, Patrick Ryan, Madelyn Joanis Jun 2019

The Theia Soteria: Alternative Design For Safer Initial Entry During Laparoscopic Procedures, Kayla Dubois, Patrick Ryan, Madelyn Joanis

Honors Theses

Laparoscopic procedures account for 15 million surgeries worldwide [1], with the initial entry into the peritoneal cavity accounting for 33-50% of all major laparoscopic complications [7]. This initial entry is the most dangerous as surgeons must enter the cavity using a sharp object with no visibility and space between the outer surface of the cavity and internal tissues. During the initial entry into the peritoneal cavity, the patients undergoing laparoscopic procedures are at a high risk for damage to internal organs and vasculature, necessitating the development of a device to protect these internal tissues and increase patient safety.


Smart Flow Facility Analysis, Chantal Ann George, Pete Suktankar, Eric Wilson, Matthew Geiger Apr 2019

Smart Flow Facility Analysis, Chantal Ann George, Pete Suktankar, Eric Wilson, Matthew Geiger

Senior Design Project For Engineers

The SMART Flow Design Team has been tasked in providing a physical layout for a single building facility used to consolidate three separate business units. The objective for the new facility will be to manufacture, receive, ship, and store the company's finished products. When designing the physical layout, the team must take into consideration stable and seasonal business volumes, current and future volume demand growth, designated inbound, outbound, and storage areas, and product turn rates. All specifications must be met while determining an efficient flow of goods. The team has designed indoor and outdoor layouts using Microsoft Visio, performed ...


Autojack - Hydraulic Powertrain System, Tyce Vu Jan 2019

Autojack - Hydraulic Powertrain System, Tyce Vu

All Undergraduate Projects

A primary problem for mechanics and automotive enthusiasts is the risk associated with lifting and securing a vehicle with conventional jack stands. Often times, improper jack-stand installation results in the vehicle collapsing unexpectedly, causing injury and/or death. This problem can be minimized through the application of a newly re-designed vehicle lifting system. The conventional method for lifting cars is time consuming and can be unsafe in many circumstances. A better, safer, and more efficient lift design was needed; the AutoJack. The approach of the AutoJack design was entirely focused on the safety of lifting a vehicle. Safety was improved ...


Project "Auxilia" - Jaiden's Prosthetic Arm, Christopher Halley, Lindsay Jaros, Autumn Young Jan 2019

Project "Auxilia" - Jaiden's Prosthetic Arm, Christopher Halley, Lindsay Jaros, Autumn Young

Williams Honors College, Honors Research Projects

The main objective of this project was to create a prosthetic arm for a 15 year old boy named Jaiden Foden. Jaiden was born with only one fully developed limb as a result of a genetic disorder, Hanhart Syndrome II. His right arm becomes a residual limb below the elbow, but has two fingers which act in a “claw-like” movement. Jaiden’s left arm becomes a residual limb above the elbow, and his left leg becomes a residual limb above the knee. The goal of the arm was to increase Jaiden’s overall independence and to help in completing daily ...


Reactive Archey Target Design Team "Mimic", Brandon Croyle, Jacob Boss, David Rodgers, Austin Wivell Jan 2019

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 ...


Fatigue Tester, Nicholas Fazio Jan 2019

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 ...


A Reticulation Of Skin-Applied Strain Sensors For Motion Capture, Christopher A. Schroeck Jan 2019

A Reticulation Of Skin-Applied Strain Sensors For Motion Capture, Christopher A. Schroeck

ETD Archive

The purpose of this research is to develop a system of motion capture based on skin-applied strain sensors. These elastic sensors are of interest because they can be applied to the body without restricting motion and are well suited to operate in more practical environments, such as sports fields, gymnasiums, and outdoor areas. This combination is currently not available in the field of motion capture. The current issues with strain sensor motion capture technology is the accurate is not sufficient for motion analysis and axial rotation monitoring of joints is not available. This project will build and test a sensor ...
