摘　　要：通过建立TC+AMT中湿式多片离合器带排扭矩与换档同步过程的数学模型,运用Matlab/Simulink进行仿真分析,并与实验结果对比,证明了模型的正确性与准确性,并分析了湿式多片离合器分离状态下摩擦副间隙、冷却油流量以及不同温度下冷却油性质等因素对带排扭矩、换挡同步时间和同步能量的影响。所得结论对湿式多片离合器的理论研究和结构设计以及传动系统匹配具有参考价值。The mathematical models of drag torque and shift synchronization process of multi-plate wet clutch were established. Simulation was carried out in Matlab/Simulink. Simulation results were compared with experiment results. It is demonstrated that the models are correct and accurate. The influences of friction pair gap in multi-plate wet clutch, cooling oil flow rate and properties of cooling oil under different temperature etc. on the drag torque, shift synchronization time and energy were analyzed. This study may provide a reference for theoretical study and structural design of the multi- plate wet clutch, and for the transmission system matching.
