摘　　要：对某款配有双质量飞轮发动机建立了曲轴系统扭振计算模型,通过扭振系统频率、转速波动、角位移的计算,分析了双质量飞轮的减振作用。计算结果表明,双质量飞轮能有效隔离发动机的振动,减小后端齿轮间的冲击,提升整车的NVH水平。It establishes a torsional vibration calculation model of crankshaft system for a certain type of engine equipped with double mass flywheel,through the calculation of torsional vibration system frequency,speed fluctuation and angular displacement,it analyzes the damping effect of double mass flywheel.The results show that the double-mass flywheel can effectively isolate the vibration of the engine,reduce the impact between the rear gears,and improve the NVH level of the whole vehicle.

关 键 词：双质量飞轮 扭振 转速波动 角位移
