  • An analytical model for fatigue crack propagation

    Creator:
    Anderson, James L.
    Abstract:
    Beginning with the basic equations from the theory of elasticity and employing a model of crack propagation based on the concept of a constant plastic energy absorption per unti of crack extension, the commonly accepted power law of fatigue crack propagation was derived. This derivation uses an extension of the...

  • Turbulence induced loads on a teetered rotor

    Creator:
    Weber, Timothy L.
    Abstract:
    Development of variable speed horizontal axis wind turbines has resulted in a need for an analysis code with a rotor speed degree-of-freedom. This study develops a five degree-of-freedom time domain computer code that evaluates blade and rotor, mean and cyclic loads with nonlinear aerodynamics together with atmospheric turbulence as a...

  • Chassis Design for the Global Formula Racing Team

    Creator:
    Powell, Zach L.
    Abstract:
    For the 2019 season, a new chassis layup was designed that is much stronger than in previous years, yet only slightly heavier. Compared to the baseline steel tube frame, the 2019 chassis has safety factors of about 110% for most zones. Also, a new impact attenuator was designed that absorbs...

  • Engineering Design Matrix for Carbon Fiber Monocoque Chassis Selection

    Creator:
    Zuck, Austin L.
    Abstract:
    The Formula Society of Automotive Engineers (FSAE) has provided a platform for teams like Oregon State’s own Global Formula Racing Team (GFR) to produce a formula style race car and compete with other schools across the world. The GFR team has used the same carbon fiber monocoque chassis since the...

  • A modeling and empirical study of a novel bimodal natural gas internal combustion engine with fuel compression capability

    Creator:
    Elgin, Robert C., III
    Abstract:
    Given the current abundant supply and cheap price of natural gas (NG) in the United States, there is a significant opportunity to use this fuel for transportation. However, there are few fueling stations for consumers. To address this need, a dual-mode engine has been developed where in one mode all...

  • Environmentally Sustainable Product Design : Understanding the Environmental Impact of Product Function and Product Labeling

    Creator:
    Ferrero, Vincenzo J.
    Abstract:
    Using repositories to store product design information can provide additional and extensive design knowledge to the global design community. Using repository data in the design of new products can be especially impactful for DfX design objectives, such as product sustainability, about which many engineering designers have limited knowledge. Furthermore, repositories...

  • Wave Energy Converter Array Optimization : Array Economic Analysis and Preliminary Results of a Genetic Algorithm Approach Introducing Cost Factors

    Creator:
    Sharp, Christopher J.
    Abstract:
    With the need to integrate renewable energy sources into the current energy portfolio and the proximity of many population centers to an ocean coastline, it is pressing that marine energy systems, specifically wave energy converters (WECs), are evaluated as potential solutions for meeting energy needs. In order to best understand...

  • Aerodynamic undertray design for formula SAE

    Creator:
    Jensen, Karl
    Abstract:
    Aerodynamic improvements in automotive racing can have a significant effect on vehicle performance. Recent developments in Formula SAE (Society of Automotive Engineers) have included the design and implementation of aerodynamic devices such as inverted wings and undertrays to improve performance. In this work the literature of undertray technology is presented...

  • Composite Tools and Optimization in Racecars to Reduce Mass and Design Time

    Creator:
    Wagoner, Marshall
    Abstract:
    Designing a carbon fiber chassis for the Global Formula Race car has historically proven to be both time intensive and difficult. The goal of this thesis is to improve the design process for testing Global Formula Racing team's composite chassis sandwich panels. Consideration was taken regarding Formula SAE rules, and...

  • How personality affects creativity in concept ideation

    Creator:
    Berthelsdorf, Friederich A.
    Abstract:
    This thesis uses the manuscript option, and consists of a previously-published paper and a paper that has been accepted for publication. Manuscript One details an independent confirmatory study to Choo et al. (2014), which demonstrated that correlations exist between personality type and the outcome of concept ideation methods. This is...
