摘　　要：以某型高能密度离合器为研究对象,对离合器接合过程的动力学特性进行分析研究,建立了离合器接合过程的动力学模型。利用ADAMS软件建立了高能密度离合器的仿真模型,研究接合过程中接合面动摩擦系数、驱动力矩、阻力矩以及接触面正压力对接合时间以及接合主从动盘角速度的影响规律,分析接触面特征点面压的变化规律。研究结果表明:接合时间与接触面正压力以及动摩擦系数成反比,驱动力矩和阻力矩决定接合最终的角速度;压力在对偶钢片和摩擦片接触面上的分布受时间和位置双重因素的影响,提取4个互成90°的特征点,分析其压力随时间的变化,4个点处的压力都有明显的周期性波动,离合器在轴向方向大致以0.05s为周期振动。High-energy clutch works in a severe condition,the power which passes the cluth can reach two or three hundred kilowatts,whether the friction disk can work normally directly related to the working performance and working reliability of the clutch.The research object of the papers is a certain type of highenergy density clutch,and dynamics analysis of combination process of the cluth is done,and the mechanical model of the combination process of wet cluth is established.By using ADAMS software,the simulation model of high-energy is established,change of contact force and distribution law of contact force is analyzed and summarized.By analyzing the change of contact force,the vibration law of cluth is studied.The results show that:the total combination time is about 0.26seconds;the distribution law of pressure on the disk is decided to time and location.the pressure of four point which is mutual 90degrees on the disk is analyzed,there exists apparent pressure cyclical fluctuations at each four point;by analyzing the contact force,the peak value of contact force can reach 25kN,and the peak value appears at the time of 0. 05,0.1,0.15,0.22,0.25seconds,the cluth librates in the axial direction by the cycle of 0.05seconds.The results provides boundary conditions for a further analysis of the temperature field,flow field of the clutch.
