摘　　要：在分析和合理简化的基础上,建立了包括曲轴柔性体部件模型、活塞连杆组和飞轮在内的刚性体部件模型以及构件间约束和作用力模型,并将它们综合建立了系统轴系的多体动力学分析模型,仿真得出系统轴系的三维振动情况,并通过实验测量验证了仿真分析结果,两者体现了较好的一致性,并得出一些有益的结论。On the basis of analysis and right-simplify,the model was established including flexible crankshaft and the rigid piston-concord,rigid fly,and multi-dynamics analysis model of system was established. The three-dimensional vibration of system was simulated, and the analysis results were verified by the test. Test results coincides well with the simulation ,and some beneficial conclusions are drawn.
