对液体粘性离合器的主动轴和摩擦片进行了瞬态响应分析,得到了液体粘性离合器在启动过程中摩擦片的应力和速度变化的情况。分析了静摩擦工况下内摩擦片花键应力分布,发现在花键与主动轴接触的地方出现了应力集中,在设计过程中应给予充分考虑。对摩擦片表面压力的分布进行了仿真,给出了压力随时间变化的规律和压力在摩擦片表面的分布。 The transient response analysis of the driving shaft and the friction plate of the liquid viscous clutch was carried out, and the stress and velocity of the friction plate during the starting process of the liquid viscous clutch were obtained. The spline stress distribution of the inner friction plate under the condition of static friction is analyzed. It is found that stress concentration occurs when the spline is in contact with the drive shaft, and should be fully considered in the design process. The pressure distribution on the friction plate surface is simulated. The law of the pressure variation with time and the distribution of pressure on the friction plate surface are given.
