摘要

Based on the finite element method and the multi-body dynamic theory,the dynamic models of cable structure were studied in the paper.An impact dynamic model of cable structures was established by adding the contact constraint into the dynamic model of cable structure.The simulation environment of the multi-body dynamic model of cable structure impact system is consisted of an active cable structure device and a passive cable structure device.The research datum shows that the finite element cable structure model engender smaller error than the multi-body cable structure model,the former is suitable for the impacting process simulation of the cable structures and for the realizing the visualization dynamic simulation.
