摘　　要：单质量飞轮是装在发动机曲轴后端的一个盘状零件,通过与离合器或连接盘和变速器传动件连接来传递动力。目前单质量飞轮转动惯量均为定值,在控制降低发动机高速阶段曲轴扭振和低速阶段转速波动时存在设计矛盾。文章论述一种应用于中小型高速汽油机的既能稳定转速波动又能减少曲轴扭振的飞轮总成设计。Currently flywheel moment of inertia is usually designed as a fixed value which re- sults in a contradiction between crankshaft front end torsional vibration control at high speed and speed fluctuation stability at low speed. In this paper, an invention of SMF assembly applied in high speed, middle and small volume gasoline engine is introduced which can not only reduce torsional vibration, but also stabilize speed fluctuation.
