  • Modeling, simulation, and analysis of two hydraulic power take-off systems for wave energy conversion

    Creator:
    Casey, Sean (Sean Michael)
    Abstract:
    Hydraulic power take-off (PTO) systems have been implemented in several wave energy converter (WEC) designs in recent years. Two popular hydraulic PTO configurations coupled to a point absorber hydrodynamic model are simulated in waves representative of an energetic sea state likely to be found in deep waters off the coast...

  • Time-domain modeling of heaving point absorber wave energy converters, including power take-off and mooring

    Creator:
    Ruehl, Kelley
    Abstract:
    Wave energy conversion is still in its infancy, and in order for it to become a commercially viable technology, developers, investors and utilities need to estimate a Wave Energy Converter's (WEC's) performance for the wave climate of a potential installation site. With the goal of estimating a design's power output...

  • Shocks and Awe : Damping Selection in Racecars to Maximize Grip

    Creator:
    Takaro, Trevor M. F.
    Abstract:
    This thesis covers the use of a quarter car model to select damping rates for aFormula Student (FS) car, focusing on minimizing vertical tire force variation to improvegrip. A 2 degree of freedom (DOF) quarter car model is cycled over the road frequenciesof interest and the results compared with the...

  • Global distributed design of a Formula SAE race car

    Creator:
    Carpenter, Trenton J.
    Abstract:
    Future engineers need to be competitive in today's expanding global industries. They must have capabilities beyond standard engineering practice. In an attempt to develop students capable of working in a globally distributed design and manufacturing environment, Oregon State University (OSU) and Duale Hochschule Baden-Württemberg Ravensburg (DHBW) have developed a senior...

  • Multi Objective Aerodynamic Design in Formula SAE

    Creator:
    Arscott, Phillip J.
    Abstract:
    This thesis examines the effect of aerodynamics on Formula SAE cars. Due to the different objectives of the Formula SAE events, an understanding of the car's complete aerodynamic design is necessary. Using a half car computational fluid dynamics (CFD) model, a series of sensitivity studies are conducted to determine trends...

  • Nonlinear model reduction using the group proper orthogonal decomposition method

    Creator:
    Dickinson, Benjamin T.
    Abstract:
    Proper orthogonal decomposition (POD) in conjunction with the Galerkin projection has been used as a model reduction technique for the tractable real-time control of high-dimensional systems. While POD based model reduction may improve the tractability of high-dimensional models, the nonlinear POD based model may be impractical for control due to...

  • Learning-based control and coordination of autonomous UAVs

    Creator:
    Bell, Adam R.
    Abstract:
    Uninhabited aerial vehicles, also called UAVs are currently controller by a combination of a human pilot at a remote location, and autopilot systems similar to those found on commercial aircraft. As UAVs transition from remote piloting to fully autonomous operation, control laws must be developed for the tasks to be...

  • A hierarchical neuro-evolutionary approach to small quadrotor control

    Creator:
    Shepherd, Jack F., III
    Abstract:
    Quadrotors are unique among Micro Aerial Vehicles in providing excellent maneuverability (as opposed to winged flight),while maintaing a simple mechanical construction (as opposed to helicopters). This mechanical simplicity comes at a cost of increased controller complexity. Quadrotors are inherently unstable, in the sense that they are essentially unflyable by a...

  • Comparing and Contrasting the Merits of Additive Manufactured Electric Vehicle Suspension Components: GFR Case Study

    Creator:
    Peraza-Garcia, Jesus
    Abstract:
    This thesis compares the implementation of additive manufactured suspension uprights against subtractive manufactured suspension uprights from concept generation, design, and validation through simulation. Additive manufactured suspension uprights were designed for Global Formula Racing’s 2023 electric vehicle. Utilizing Siemens NX, Nastran, Fusion 360, and Ansys Workbench both subtractive and additive manufactured...
