  • 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...

  • 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...

  • Cold trap performance : a general analysis

    Creator:
    Rothwell, Micheal Olin
    Abstract:
    A cold trap is a device used to remove certain impurities from a liquid metal by controlled precipitation of such impurities. An investigation of the thermal characteristics of laminar flow in two air-cooled cold traps was made. This investigation showed that the sodium heat transfer rate is a function of...

  • A study of ignition and propagation of combustive synthesis reaction between titanium and carbon

    Creator:
    Hernandez-Guerrero, Abel
    Abstract:
    Combustive Synthesis or Self-Propagating High-Temperature Synthesis (SHS), is an energy-efficient combustion method of producing metallic, ceramic and composite materials from their constituent powders. This thesis presents the results of an experimental and numerical evaluation of the propagation velocity for the SHS solid-solid reaction of titanium and carbon, as well as...

  • Risk-based design for multidisciplinary complex systems

    Creator:
    Farhangmehr, Farzaneh
    Abstract:
    The ultimate goal of large-scale design organizations are mainly to reduce costs and improve reliability and performance of systems while assessing how much risk (cost, schedule, scope) they can take and still remain competitive. To achieve this goal they need to develop tools to reach the most preferred design product...

  • Design of Complex Engineered Systems Using Multiagent Coordination

    Creator:
    Soria Zurita, Nicolás Francisco
    Abstract:
    This thesis is the combination of two research publications working toward a unified strategy in which the design of complex engineered systems can be completed using a multiagent coordination approach. Current engineered system modeling techniques segment large complex models into multiple groups to be simulated independently. These methods restrict the...

  • A study of laser generated Rayleigh and Lamb waves in graphite/epoxy composites

    Creator:
    Park, Heeyong
    Abstract:
    The application of laser generated ultrasonics was first demonstrated in the mid-seventies and has shown good potential when applied to isotropic materials. However, its use with composite materials is still in the early stages of development. This study explores the potential for application of laser generated Rayleigh and Lamb waves...

  • Rope Selection for Rope Drive Transmissions Used in Robotic Manipulation

    Creator:
    Summers, Michael P.
    Abstract:
    Wire and fiber ropes used in rigorous CBOS (cyclic bend over sheave) applications were investigated. Small diameter stainless steel, tungsten, and Vectran® ropes were tested over small sheaves at high loads and cycle speeds. Sheaves were made with Al6061-T6511 and Al7075-T651 and were coated with 0.002” hard coat anodize; some...
