    Abstract: Aiming at the problems of dynamic analysis on multi-body systems with redundant constraints, a solution based on the dynamic simulation in Mechanism module of Pro/E is proposed and illustrated with an example of a translational platform with multicrank. A three-dimensional model of the system is built simplified to fit the pivot in the research. Comprehensive dynamic simulation is performed based on the application of virtual prototyping technology in Pro/E. The factors which impact the motion and reacting forces of the platform are analyzed with simulation results. The optimized design is then considered.
