根据简化动力－传动系统为多自由度弹性－集中质量系统的原则，提出了带有闭锁式液力变矩器的车辆动力－传动系统的力学模型和数学模型．对闭锁式离合器的闭锁过程进行了动态仿真计算，得出了这一过程中闭锁式液力变矩器主、从动部分的动载扭矩和角速度随时间的变化规律，并分析了对其产生影响的因素．
According to the principle of simplifying the power-transmission system for multi-degree of freedom elastic-mass system, a mechanical model and a mathematical model of vehicle powertrain with a lock-up torque converter are proposed. The locking process of the lock-up clutch was simulated by dynamic simulation. The change rule of the dynamic torque and angular speed of the main and driven parts of the lock-up torque converter with time was obtained. Factors affecting.
