  • Rebound predictions of mechanical collisions

    Creator:
    Lai, Liang-Ju
    Abstract:
    Predictions of mechanical collisions between two bodies frequently cannot be completed by the impulse-momentum equation together with a complete description of the motion of the system at the initial contact. Additional account must be taken of the deformations and frictional interaction induced by the impulsive reaction force, where the bodies...

  • Derivation and automatic generation of Kane's dynamical equations for mechanical manipulators

    Creator:
    Nie, Tinglin
    Abstract:
    To design and precisely control a manipulator requires developing an efficient dynamic model of the system. The present work demonstrates how this can be accomplished by employing Kane's dynamical equations. First, a detailed manual derivation of the equations of motion for a particular robot is presented in such way that...

  • An aeroelastic analysis of the Darrieus wind turbine

    Creator:
    Meyer, Edward Earnest
    Abstract:
    The stability of small oscillations of the troposkeinshaped blade used on Darrieus wind turbines is investigated. The blade is assumed to be attached to a perfectly rigid rotor shaft and spinning in still air. Linear equations of motion are derived which include the effects of in-plane, out-of-plane, and torsional stiffness,...

  • A model reference adaptive system for control of a flexible mechanical manipulator

    Creator:
    Lee, Byeung Kyun
    Abstract:
    For control of a flexible manipulator, the assumed- mode method is applied to the mathematical model of the model reference adaptive system. In the assumed-mode method, the flexible, continuous manipulator is described by a limited number of degrees of freedom. A modified model reference adaptive system is studied for direct...

  • Parameters affecting mechanical collisions

    Creator:
    Aum, Ho Sung
    Abstract:
    Even though the elastic deformations that occur during the impact of colliding bodies may be small in comparison to their actual dimensions, they play an important role in mechanical collisions. During the time the bodies are in contact, elastic, friction, and inertia properties combine to produce a complex variation of...

  • Rebound predictions for elastic collisions

    Creator:
    Liu, Pao-pao
    Abstract:
    In this paper, a numerical method is used to predict the response of an elastic body during a collision in which both normal and tangential impulses are important. Results are compared with those from simplified prediction procedures, which stem from the assumptions that the energy-returning capacity of the normal deformation...
