Dynamic Modelling of Hoisting Steel Wire Rope
Abstract
Aiming at the steel wire rope and its connecting mechanism, the modeling method and dynamic behavior analysis was carried out. The flexible multibody dynamics model of the rope was established by using cable element basing on the absolute nodal coordinate formation, while, other parts in the connecting mechanism were simplified as rigid bodies. The contact impact force between the flexible rope and other rigid bodies was incorporated into the dynamic model through the Hertz contact theory. Finally the rigid-flexible coupled dynamic model which can describe the large rotation and large displacement of the whole steel rope system was established. The simulation of the steel rope’s dynamic model was presented. The results show that the developed model can be used in the analysis of dynamic behavior and the accurate control of the motion.
