Dynamics of digitally controlled forced vibration of suspended cables

چکیده
Abstract Dynamics of suspended cables with active vibration control is studied. The device an electrical absorber that driven by a motor and may be fixed at any position along the cable. applies force reduces amplitude where it placed. methodology efficient for attenuating high-frequency, low-amplitude due to periodic excitation consider wind effect. dynamic behavior described mechanical model cable location attached. takes into account such practical problems as time delay backlash driving, which lead limitation in applicability control. Time occurs digital control, because samples data are taken discrete intervals response provided after sampling delay. Backlash influences when direction changes, since not transmitted small domain backlash. present research examines effects on local vibration, assesses range can applied successfully. Moreover, presence together results motion some irregularity what justifies detailed study order evaluate types arise systems.

The weakly nonlinear in-plane free vibrations of a single suspended cable, or a coupled system of suspended cables, may be classified as gravity modes (no tension variations to leading order) and elasto-gravity modes (tension and vertical displacement equally important). The gravity mode (probably the most common type of vibration of relatively inelastic spans) does not exist for particular val...
متن کاملDynamics, Control and Planning for Cooperative Manipulation of Payloads Suspended by Cables from Multiple Quadrotor Robots
We address the problem of cooperative transportation of a cable-suspended payload by multiple quadrotors. In previous work, quasi-static models have been used to study this problem. However, these approaches are severely limited because they ignore the payload dynamics, and do not explicitly model the underactuation in the control problem. Thus, there are no guarantees on the payload trajectory...

THE TECHNIQUE OF DETERMINATION OF STRUCTURAL PARAMETERS FROM FORCED VIBRATION TESTING Wai Fan Tsang This thesis details the results of an investigation into a technique for determination of "useful" structural parameters from forced vibration testing. The implementation of this technique to full scale civil engineering structures was achieved by several developments in the experimental and comp...
