Loads 2-Degree of Freedom Swing Angle Model and Dynamic Simulation for Overhead Crane or Gantry Crane
Exactly positioning of the trolley and promptly eliminating of the load swing for bridge crane arc efficient approaches in order to improve the operational efficiency of over-head cranes and gantry cranes. So, it is necessary that model construction for dynamic equations of the trolleyload system and finding out load swing rules and decision factors of loads swing angel while studying anti-swing control scheme. Construct 2-degree of freedom angels math model of the load-swing through constructing the trolley-load systems dynamic 3dimention (3-D) equations, and properly simplify those equations. The ropes length of load and trolley-acceleration can obviously affect the swing angels value of load. Dynamic simulation results show that the rope-lengths force is more prominent than the trolley-accelerations for the swing angel of load and the trolleys running acceleration (deceleration) can obviously affect the value of loads swing angle when the rope length is determined, the value will increase with increasing acceleration (deceleration), and the trolleys running acceleration (deceleration) can not obviously affect the loads swing frequency.
