  • Design and analysis of a high speed dynamic tow carriage

    Creator:
    Lovejoy, Steven C.
    Abstract:
    A need exists to develop a high speed dynamic tow carriage used to motivate hydrodynamic specimens through a fluid environment. It is desired to simulate high Reynolds number unsteady flow about the specimen by towing the specimen through the fluid. The fluid environment is to be provided by the existing...

  • 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...

  • 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...

  • Dynamics and control of a rigid/flexible manipulator

    Creator:
    Yeh, Chun-tien
    Abstract:
    Control of high-speed, light-weight robotic manipulators is a challenge because of their special dynamic characteristics. In this work, a two-stage control algorithm for the position control of flexible manipulators is proposed. First, the more complex, flexible robot system is replaced by a simplified hypothetical rigid body system (HRRA) with off-line...

  • 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,...

  • 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...

  • 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...

  • 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...

  • Normal modes in nonlinear nonsymmetrical systems with two degrees of freedom, and applications to air springs

    Creator:
    Moustafa, Mahmoud Abd-Elfattah
    Abstract:
    The study of nonlinear vibrations of systems having two degrees of freedom has met considerable attention during the past few years. Nonlinear symmetrical systems have received most of it. Normal mode motion of a system is defined as a periodic motion such that the masses of the system assume repeated...

  • Vibrations of suspended cables

    Creator:
    Gale, John Gregg
    Abstract:
    The equations of motion of an elastic cable suspended in a viscous medium from two arbitrary points are derived. These are then linearized for the undamped, inextensible case, and it is found that the equations describing the in-plane motion of the cable are then independent of the equation describing the...
