The main objective of this study was to model and simulate a multi-flexible-body three-dimensional model for researching the Multi – rope Friction Winder system. By introducing the multi-flexible-body dynamics method, a multi-flexible-body virtual prototype of the winder is been builded with the RecurDyn software package. Kinematics and dynamics characteristic date are obtained by computer-aided dynamic simulation of virtual Multi – rope friction winder. The result is in accord with theoretical analysis. The research work will provide a powerful tool and useful method for the design of economic and credible elevator system. The approach can be generalized to analysis other flexible drive fields.
