摘　　要：通过EXCITE Designer软件,建立两缸柴油机曲轴轴系动力学模型,输入主要的仿真参数,得到了无减振器曲轴扭转振动和带减振器曲轴扭转振动的仿真计算结果,通过仿真计算结果分析与对比,带减振器曲轴扭转振幅明显下降,曲轴扭振振幅在可接受的范围内。The dynamic model of D09 two-cylinder diesel engine crankshaft system is established through the EXCITE Designer software.The main simulation parameters are input,and the simulation results of crankshaft torsional vibration without damper and crankshaft torsional vibration with damper are obtained.Through the analysis and comparison of the simulation results,the torsional amplitude of crankshaft with damper is significantly reduced,and the torsional vibration amplitude of crankshaft is within an acceptable range.
