abstract

  • The Multidisciplinary Design Optimization (MDO) system is needed to reduce the
    developing time and production cost in most industries. The MDO is the new technology for
    optimization design, and considers solid mechanics, dynamics, kinematics, vibration/noise
    control, and fluid mechanics, simultaneously. Higher product quality, less developing time and
    lower manufacturing cost will be achieved through a balanced and organic MDO method. In this
    paper, numerical stress analysis, optimization method, and experimental stress analysis will be
    conducted to accomplish: 1) production cost; 2) developing time; 3) quality improvement; and 4)
    service-rate drop. First, the coupled analysis using the finite element method will be performed
    to obtain the accurate data. Second, OPTISTRUCT, which is commercial optimization software,
    will be used for shape and size optimization analysis. Third, an experimental stress analysis
    system will be established to assist the optimization design and numerical analysis.
