  • 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)...

  • 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...

  • Diagnostic analysis for mechanical systems

    Creator:
    Henning, Scott A.
    Abstract:
    An analysis and modeling method of the diagnostic characteristics of a mechanical or electromechanical system is presented. Diagnosability analysis is especially relevant given the complexities and functional interdependencies of modern-day systems, since improvements in diagnosability can lead to a reduction of a system's life-cycle costs. The diagnosis process of a...

  • 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...

  • Alternative design considerations for a wave energy converter : a sustainability approach

    Creator:
    Collins, Erin
    Abstract:
    As the negative impacts of a fossil fueled electricity market are becoming more prevalent and destructive, the necessity for alternative energy techniques increases as well. However, before commercial implementation is underway, these alternatives must be assessed from three important perspectives: environmentally, economically, and socially, which are known as the three...

  • 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%...

  • Drilling process evaluation by predicting drilled hole quality and drill bit wear with on-line acoustic emission signals

    Creator:
    Wang, Kuang-Jen, 1962-
    Abstract:
    Improvement of manufacturing productivity is dependent on the successful automation of manufacturing processes, the success of which is based in turn upon the availability of information which describes the state of manufacturing operations. Acoustic Emission (AE) signals related to the cutting process and tool wear have been recently applied to...

  • The wave energy resource of the US Pacific Northwest

    Creator:
    Lenee-Bluhm, Pukha
    Abstract:
    The substantial wave energy resource of the US Pacific Northwest (i.e. off the coasts of Washington, Oregon and N. California) is assessed and characterized. Archived spectral records from ten wave measurement buoys, operated and maintained by the National Data Buoy Center and the Coastal Data Information Program, form the basis...

  • Optimal troubleshooting plan for a complex electro-mechanical system

    Creator:
    Durgi, Parthsarathy
    Abstract:
    The decision sequences used for troubleshooting of complex electro-mechanical systems are often ad hoc and less than optimal. This research investigated Decision Analysis and Bayesian Networks for generating an optimal decision sequence for troubleshooting. The model that was used in this research was the bleed air control system of the...

    Creator:
    Theroff, Zachary
    Abstract:
    This project consists of the analysis, design, and manufacturing of the 2016 cooling system for Global Formula Racing’s combustion vehicle. Several water configurations were examined, using computational fluid dynamics (CFD) to estimate airflow and heat transfer calculations in MATLAB to estimate heat rejection through each concept. Data used to perform...
