车辆闭锁式液力变矩器闭锁过程动态性能研究

Transient Characteristics of Torque Converters in Vehicles During the Locking-up Process

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．

Taking a power-hydrodynamic transmission system as a spring-mass system having multi-degrees of freedom, a dynamic model and mathematical model have been established for the vehicle power-train equipped with a torque converter having lock-up functions. Simulated calculations for the system are carried out in the process of locking-up. Factors affecting the transient load of power-train system are analyzed.
