Abstract:

Based on dynamics virtual prototype technique and the theory of analysis of multi-body dynamics system, visual design was put forward trying to take visualization as design means to inspect the performance of multi-body dynamics system at every aspect. Combining with three-dimensional model in Pro/E, the dynamics virtual prototyping of multi-body dynamics system was established based on ADAMS platform, as well as combining software ANSYS with the dynamics virtual prototype, flexible body was established. In the condition of virtual prototype, utilizing assembly process visualization, dynamics visualization, operation process and kinematics visualization, the research were put up to testify the validity of visual design. In addition, the application results reveal that the visual design can improve the design quality of products in an all-round way based on the virtual prototype. The important capability parameters of multi-body dynamics system are obtained and some interrelated parameters that influence the capability and natural life of the system are analyzed, and references are provided for ameliorating the design of similar products.
