  • Development of a singulation device for stonefly larva

    Creator:
    Williams, Kate S. (Kate Shreeve)
    Abstract:
    Population counts of aquatic insects can be a credible indicator of the overall health of a waterway. Stonefly (Plecoptera) larva are very sensitive to chemicals present within the waterway, however obtaining population counts of the larvae can be very labor intensive and thus costly. The BugID project has been working...

  • Distortion-induced fatigue cracking of girder-to-crossbeam connection

    Creator:
    Aljutaili, Dhari S.
    Abstract:
    Oregon Department of Transportation’s bridge no. 9743b is a multi-span, two-girder steel deck bridge connecting the busy interstates 5 and 205. Vertical cracks have been detected in the welded girder-to-crossbeam connections at the bents. Distortion-induced fatigue is suspected to be responsible for the cracking. Linear elastic beam analysis, 2-D and...

  • Automating aquatic insect identification through pattern recognition

    Creator:
    Thomas, Joshua K.
    Abstract:
    Aquatic insect population counts can be a good indicator of the health, or water quality, of rivers and streams. Stoneflies (Plecoptera) are particularly susceptible to pollution in streams. However, today’s current method for obtaining these population counts requires biologists to examine individual specimens under a microscope for identification to the...

  • Design of composite sandwich panels for a Formula SAE monocoque chassis

    Creator:
    Story, Robert D.
    Abstract:
    Physical testing of composite sandwich panels in three point bending is an increasingly important aspect of qualifying a composite monocoque for Formula SAE competition. Required stiffness and strength values have increased over the past three years, and more of the monocoque's laminates must be tested as well. As a result,...

  • Vehicle dynamic validation and analysis from suspension forces

    Creator:
    Murray, William S.
    Abstract:
    Several standardized courses for Formula SAE (FSAE) testing are introduced and described with sufficient detail to be reproduced by any Formula SAE team. Basic analysis methods for the courses are given as well as explanations of how those analyses could be used. On-car data from the Global Formula Racing (GFR)...

  • CFD Model Analysis and Validation for a Formula SAE Racecar

    Creator:
    LaFranchi, Alexander
    Abstract:
    This project examines the computational fluid dynamics (CFD) model used by Global Formula Racing (GFR) to simulate external aerodynamics for a Formula SAE racecar. It seeks to improve the accuracy of the existing model by changing mesh and physics model parameters. Accuracy of the model is quantified through comparison to...

  • Simulation Automation for the Evaluation of Formula Student Aerodynamic Concepts

    Creator:
    Sanchez, Adrian
    Abstract:
    The design of a competition-winning aero package must consider multiple vehicle attitudes. Aerodynamic concepts simulated in heave, pitch, roll, high-speed yaw, and low-speed yaw to design a stable and predictable aero package. The methodology automates the simulation setup process of five vehicle attitudes. The overall and subsystem force coefficients are...

  • Design of an automated system for imaging and sorting soil mesofauna

    Creator:
    Chamblin, Mike A.
    Abstract:
    Identification and population counts of soil mesofauna can be an important tool for soil ecologists to determine the soil biodiversity. Information provided from population counts can give insight to soil ecologists about the effects of human land use, monitoring soil and water health, benefits of soil biodiversity in agriculture, and...

  • Utilizing the thermodynamic properties of E85 to increase the specific efficiency of a high specific output single cylinder Formula SAE engine

    Creator:
    Duncan, Derek N.
    Abstract:
    Formula SAE is a collegiate engineering competition that has participants from around the globe. Of the 1000 points available throughout the event, 100 (10%) are dedicated to the fuel efficiency of the student built race cars. Competition rules allow either gasoline or E85, a mix of 85% ethanol and 15%...

  • Analysis, testing, and redesign of an environmental control system for an engine dynamometer

    Creator:
    Morris, Taylor H.
    Abstract:
    This project analyzes, tests, and redesigns an environmental control system for Global Formula Racing’s (GFR) dynamometer. It seeks to develop a working system to test GFR’s car engine under air conditions similar to those faced during competition. A model is developed to predict the performance of the environmental control system,...
