Load’s Damping Swing by Trolley’s Driving Force Control for Overhead or Gantry Crane

Abstract:

In order to obtain the trolley-load system’s dynamic equations for overhead crane or gantry crane, analyzed the dynamic system and deduced the transfer function between the load’s sway angle and the force acting on the trolley from dynamic equations. The force control mode for load’s damping swing is an effective measure of compensation for active anti-swing. Dynamic simulation results show that the optimal evacuation time of the force acting on the trolley is a key parameter that affects the damping swing’s effect. The load’s damping swing effect is favorable when the driving force is withdrawn at optimal withdrawing time; the load’s swing angle’s amplitude will increase with driving force’s increase, but the damping swing effect is still favorable if the optimal withdrawing time is favorably controlled.
