摘要
采用结合有限元法(FEM )的多体系统仿真(MSS)方法对汽车发动机曲轴进行扭转振动分析。建立了包括柔性曲轴的车用发动机曲轴系统的多体动力学模型。根据多体动力学仿真计算结果,分析了曲轴的扭转振动,测量了曲轴自由端的扭转振动,与仿真计算结果吻合较好。
By using multi-body system simulation (MSS) method, combined with fin ite element analysis (FEA), the torsional vibration of automotive engine cranksh aft is analyzed in this paper. The multi-body dynamics model for the crankshaft assembly including flexible crankshaft is established. The torsional vibration o f crankshaft is analyzed based on the results of multi-body dynamics simulation . The torsional vibration at the free-end of crankshaft was measured, which coin cides well with the simulation.
