中文摘要：
为了解决液粘调速离合器摩擦副偏磨问题，提高液粘调速离合器摩擦片运动系统的响应速度，提出了一种新型双活塞结构液粘调速离合器。基于摩擦片受力模型，推导出了双活塞结构液粘调速离合器摩擦片间油膜的动态平衡方程及传递函数，并对其动态特性进行了理论分析及仿真研究。结果表明：双活塞结构液粘调速离合器与单活塞的相比输出响应速度明显提高；在输出转速为80rad／s时，其响应时间可由52s减少到22s。
英文摘要：
In order to solve the uneven wear problem of frictional disks of HVD clutch and improve its response speed, a new HVD clutch with double-piston structure is proposed, and its working principle is analyzed. Based on mathematics model of frictional disks, the oil dynamic balance function and transfer function for the new HVD clutch are obtained, and its dynamic characteristics is studied by theory analysis and simulation. The results show that compared with the ordinary HVD clutch with singular- piston, the new HVD clutch has a faster response speed. The response time can reduce from 52 s to 22 s when the output speed is given as 80 rad/s.
