Abstract

The dynamics model of multi-rigid body and flexible multi-body in a engine crankshaft system was built for the different analytic emphasis with software of virtual prototype based on dynamics theory of multi-rigid body systems and flexible multi-body systems.Dynamics parameters,such as action force on the crank-pin,piston sidewall force and spectrum line of torsional vibration of crankshaft were calculated form simulated model.Expedience and reliability of simulation analysis of engine crankshaft system based on virtual prototype were confirmed form a point of view,and a foundation was given for the design of engine crankshaft system.
