  • Mechanical design history content : the information requests of design engineers

    Creator:
    Kuffner, Tom A.
    Abstract:
    This thesis reports on research conducted to determine the information which should be included in a mechanical design history. This is part of a larger research effort aimed at developing a computer tool for storing and replaying mechanical design history information. Three question-asking protocols were conducted to determine what information...

  • Model based visualization of vibrations in mechanical systems

    Creator:
    Jitpraphai, Thanat
    Abstract:
    To visualize vibrations in mechanical systems, e.g., machine tools, their movements are measured by means of suitable sensors. The signals from these sensors are processed and displayed as animated pictures on a computer screen. Accelerometers have been chosen as the most suitable sensors for this purpose. Their main advantages include...

  • A methodology for iterative design using physical test data

    Creator:
    Morris, Wesley T.
    Abstract:
    This thesis addresses a common knowledge gap that was identified amongst the Society of Automotive Engineers (SAE) competition design teams at Oregon State University. Students that join the SAE teams at Oregon State University typically do not have experience using physically collected data during a design process. This leads to...

  • Data Mining a Design Repository for Automating and Validating Functional Modeling

    Creator:
    Mikes, Alex B.
    Abstract:
    The purpose of this work is to build a foundation of understanding and methodologies as the steps toward automating functional modeling. We have achieved significant progress in the automatic generation of functional representations, which can be connected at the interface of components to create a functional model. This work highlights...

  • Data-Driven Numerical Modelling of an Oscillating Water Column from Physical Tank Testing Data

    Creator:
    McKee, Aisha I.
    Abstract:
    Wave Energy Converters (WEC) have great potential to help meet global energy demands, but even a single device can be challenging to model. Although most WEC concepts are modelled, many have been simplified with assumptions that do not accurately capture the true dynamics of the system. For this reason, data-driven...

  • Constrained thin film desorption through membrane separation

    Creator:
    Thorud, Johnathan D.
    Abstract:
    A constrained thin film desorption scheme has been experimentally tested to determine the desorption rates for water from an aqueous lithium bromide mixture through a confining membrane. Variable conditions include the inlet concentration, pressure differential across the membrane, and channel height. Desorption takes place in a channel created between two...

  • Modeling the thermal effects of fabricated fuel-to-cladding gap in fast reactor fuel

    Creator:
    Baker, Ronald Blair
    Abstract:
    This report presents a refined method for the calculation of fuel centerline temperatures and the linear-heat-rating-to-incipient melting, ' Q'[subscript m], of mixed-oxide fuel typical of that to be used in the Fast Flux Test Facility and in Liquid Metal Fast Breeder Reactors. Of primary concern are the effects of the...

    Haluzak, Charles Craig
    Abstract:
    An experimental biomass combustion facility has been built and established at Oregon State University. The furnace, or Biomass Combustion Unit ( BCU ), uses an augertype fuel feed system, grate-type fuel support with under and over fire air supply. Fourteen pellet species from five States - Alaska, Washington, Oregon, Idaho,...
