Vehicle Multi-Pass Rut Volume And Mobility Power Study, William W. Barbour
Vehicle Multi-Pass Rut Volume And Mobility Power Study, William W. Barbour
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
This paper presents the relationship between applied power by a wheeled vehicle to soil and the rutting effects. Specifically, a strong positive relationship was found between cumulative applied power and total rut volume across multiple passes by the vehicle over the same tracks. Field-testing was conducted using a high-mobility multi-purpose wheeled vehicle (HMMWV) and two distinct soil types. Sensors on the vehicle measured torque and angular velocity of each of the four wheels, from which applied power was calculated. A rut profile meter was used to document the shape of the rut after set numbers of passes and this profile …

Asme Human Powered Vehicle Competition Frame Design, Zacarie Hertel
Honors Theses
Each year, the American Society of Mechanical Engineers (ASME) sponsors the Human Powered Vehicle Challenge. The purpose of the competition is to provide a continued source of research into human powered vehicles. Generally, the vehicles for this competition consist of faired recumbent tricycles and bicycles, capable of reaching high speeds in an efficient manner. The subject of this report is the design and analysis of a new vehicle frame for Union’s 2014 competition entry. The frame is the structural skeleton of the vehicle, supporting the rider and all vehicle components. The frame is what withstands the majority of the loads …
Adding Vision To A Quadrotor: A Design-Build-Test Adventure, Darren Tinker
Adding Vision To A Quadrotor: A Design-Build-Test Adventure, Darren Tinker
Mahurin Honors College Capstone Experience/Thesis Projects
Quadrotors are small and exceptionally agile vehicles with maneuverability that permits both indoor and outdoor flight. The vast majority of quadrotors are flown autonomously as drones or remotely by a human-operator. Applications of quadrotors range from commercial deliveries, to military and law reconnaissance as well as research tools for various fields. Our lab at Western Kentucky University built a quadrotor in 2013, and we have been exploring various modifications to refine its performance and various applications in which it could be productively employed. Recently, research has focused on the addition of a camera to add capabilities for first person view …

Racing in supermileage car competitions has been the norm at Cedarville Univesity since 1991. In these competitions, first with SAE (1991-2010) and now with Shell (since 2007), the teams of Cedarville engineering students have gained practical learning knowledge while winning awards in the process.
The Design Of A Mobile, Animatronic Bald Eagle, Eric Burns
The Design Of A Mobile, Animatronic Bald Eagle, Eric Burns
Phi Kappa Phi Research Symposium (2012-2016)
Modern animatronics are used as a tool to help engage audiences in realistic and entertaining experiences. Many animatronic figures are dynamic in movement, but static in mobility. The research presented covers the beginnings of mobile animatronic research. An animatronic bald eagle, Opportunity, was designed for that purpose. Animations for Opportunity are generated by integration of Arduino, Pololu Mini Maestro, and Hitec Servo Motors. Arduino receives signals from flex sensors which cause voltage variations when “flexed”. The 1:1 scale, animatronic eagle can be perched on the arm of an “actor” who simulates an eagle’s caretaker. The flex sensors are located within …

Four Cedarville seniors are building and testing wooden bicycles for a capstone engineering project. Team leader Jake Miller said the project offers a unique opportunity for students to connect their interests in engineering, woodworking and cycling.
Understanding Chassis Inputs From The Rear Suspension Of A Snowmobile, Jamie L. Kleinendorst
Understanding Chassis Inputs From The Rear Suspension Of A Snowmobile, Jamie L. Kleinendorst
Dissertations, Master's Theses and Master's Reports - Open
Today’s snowmobile industry faces great challenges in the field of noise & vibration. The area of main concern is the pass-by noise restriction defined by the Society of Automotive Engineers (SAE) test standard J192, with a maximum sound pressure level of 78 dB(A) being required by many states and national parks. To continue meet or beat this requirement without effecting machine performance, a deeper understanding of the sound transfer paths is required. This thesis examines the transfer paths created by the tunnel, rear suspension, drive shaft, and rubber composite track, with the primary source being suspension input through the ground. …
Numerical Investigation Of Boiling In A Sealed Tank In Microgravity, Sonya Lynn Hylton
Numerical Investigation Of Boiling In A Sealed Tank In Microgravity, Sonya Lynn Hylton

NASA's missions in space depend on the storage of cryogenic fluids for fuel and for life support. During long-term storage, heat can leak into the cryogenic fluid tanks. Heat leaks can cause evaporation of the liquid, which pressurizes the tank. However, when the tanks are in a microgravity environment, with reduced natural convection, heat leaks can also create superheated regions in the liquid. This may lead to boiling, resulting in much greater pressure rises than evaporation at the interface between the liquid and vapor phases. Models for predicting the pressure rise are needed to aid in developing methods to control …

Mathematics, Engineering, Science Achievement (MESA) outreach programs are partnerships between K-12 schools and higher education in nine states. MESA efforts introduce integrated experiences in science, mathematics and engineering to K-12 students from groups that are traditionally underrepresented in the STEM disciplines. This exploratory study examined the influence of selected MESA activities on students' self-efficacy, their perceptions of engineering, and their interest in engineering and other STEM fields. Field trips, guest lecturers, design competitions, hands-on activities and student career and academic advisement were of specific interest in this survey. The project also investigated the relationship between student engagement in MESA and …
