摘　　要：针对MSCAdams难以完成大变形柔性体的建模及仿真,提出将一根钢丝绳细化成若干绳节,绳节之间采用线性衬套连接的建模方法.运用Adams的宏命令完成滑轮-绳索机构的装配及约束添加,通过合理设置仿真参数,进行动力学仿真.仿真结果验证了滑轮-绳索机构建模的合理性,为滑轮-绳索机构的冲击和振动问题提供了理论依据.Aiming at the difficulty of completing the modeling and simulation of large soft body using MSC Adams,this paper puts forward a modeling method by fractionizing a steel rope into several rope segments,which are connected by linear bush.Assemble the chain rope pulley mechanism and add restriction using the macrocommand of Adams.Make dynamics simulation by setting the simulation parameters reasonably.Simulation validates the rationality of the chain rope pulley model,providing the theory for impact and vibration of the rope pulley mechanism.
