Multi-body Dynamics Simulation on Flexible Crankshaft System

摘要

A virtual prototype of flexible multi-body crankshaft system of engine is used to do the dynamics simulation. The theory of flexible multi-body systems dynamics is combined with FEA method to study the crankshaft, the dynamic boundary loads on the joints in a working cycle are determined by the simulation on the crankshaft system. The real-time dynamics response of the crankshaft in a cycle is achieved. It provides an important foundation for the crankshaft optimum design.
