  • Mechanical design under changing customer requirements case study : BugID

    Creator:
    Fagan, Chris R.
    Abstract:
    Customer requirements and engineering specifications will influence the direction of the design in any product, so it is crucial to make the requirements as stable as possible so quality designs can be produced on time within a budget. It would be optimal for requirements and specifications to remain constant but...

  • The Design of a Multidisciplinary Capstone Course

    Creator:
    Rust, Nathan R.
    Abstract:
    The end goal of any educational program is to prepare a student for the challenges they will see after completion of their studies. In the realm of engineering, the pinnacle of this occurs during a student’s final Capstone course series, where students are asked to apply their various skills learned...

  • Reliability centered prediction technique for diagnostic modeling and improvement

    Creator:
    Murphy, Michael D., 1965-
    Abstract:
    Design phase decisions based on diagnosability lead to lower system costs and, in turn, higher quality products by means of reducing maintenance time and increasing system reliability. A case for diagnosability is presented. Functions of diagnosability are expounded upon including life cycle costs, statistical analysis, and design criterion to emphasize...

  • 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...

  • The effects of ocean variability and breaking waves on wave energy converter reliability and survivability

    Creator:
    Brown, Adam
    Abstract:
    The reliability and survivability of a wave energy converter (WEC) is highly dependent on the variability and non-linearity of the ocean itself. Ocean variability occurs on many time scales. Climate variability occurs decade-to-decade, and year-to-year in the number and intensity of winter storms. Seasonal variation of wave height and period...

  • Performance Evaluation of Air Shocks Implemented in a Formula Student Vehicle

    Creator:
    Fritz, Tim
    Abstract:
    The Formula Student Team Global Formula Racing from Oregon State University implemented an air suspension system in their 2017 combustion powered vehicle, mainly to save weight. This thesis covers the performance evaluation of such system by comparison to conventional coil over shocks. Utilizing two different Formula Student style courses, three...

  • The Design and Development of Custom Rear Brake Calipers for the Oregon State University Formula SAE

    Creator:
    Van Horn, Allison
    Abstract:
    Rear brake calipers are a critical component of the brake system within a vehicle. Brake calipers function by clamping against the brake rotor when the brake pedal is pressed by the driver and thus results in deceleration of the vehicle. This thesis aims to design and develop custom rear brake...

  • 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...

    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...

  • Ergonomic Analysis of the Global Formula Racing Driver Interface

    Creator:
    Davis, Sean M.
    Abstract:
    Between Oregon State University and DHBW Ravensberg, Global Formula Racing produces two Formula style vehicles every year for competition. This thesis has served as a pre-development project in the ergonomics and driver interface of the team's vehicles. This project will determine the position of the seat back, steering wheel, and...
