  • An empirical study on the process of mechanical design

    Creator:
    Stauffer, Larry A.
    Abstract:
    An information processing model of the problem-solving performance of mechanical designers is presented for four design tasks: conceptual assembly design, layout component design, detail component design, and catalog selection. These tasks are organized into six kinds of segments called episodes, which describe the goal structure of the designer while performing...

  • 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...

  • A computer-based design history tool

    Creator:
    Chen, Ai-hua
    Abstract:
    In current practice, design documentation often fails to support the activities of design understanding, communication, and redesign. A Design History Tool has been developed to improve current design documentation. This tool is a computerized design history that represents and plays back important information generated during the process of designing a...

  • The design capture system : capturing back-of-the-envelope sketches

    Creator:
    Hwang, Teng-shang
    Abstract:
    A system which allows the computer to capture sketches made by a mechanical designer is described. The system not only recognizes basic features as they are sketched, but it also reasons the spatial relationships between features and builds a high level abstract representation (feature model) of the artifact. The temporal...

  • 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...

  • Experimental and analytical characterization of bidirectional reflectance data for engineering materials

    Creator:
    Zaworski, Joseph Robert
    Abstract:
    Bidirectional reflectance is a fundamental property used for the analysis of radiative heat transfer. It is a form of reflectivity in which the spectral and directional dependencies of both the beam incident on a surface and the beam reflected from the surface are specified. A new system has been designed...

  • 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...
