Study on Multibody Dynamics Modeling of Chain Drives Based on ADAMS

Wu Jiang

Abstract

Multibody dynamics model of chain drives including objects' contact was established by MSC. ADAMS software base on the contact mechanics theory. In view of the long time simulation as multi-contact was involved, the method to simplify the situation by replacing the contact with approximate force is proposed, which speeds up the simulation beyond one time, and to some extent reduced the simulation overall error. It provided the appropriate virtual prototyping model to the chain drives' mechanism optimization analysis and the whole machine simulation, and offered optimization reference for similar models sach as belt drives and track drives.
