| Abstract: | 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. |
