摘要: 液力变矩器是车辆液力机械传动系统中的关键部件,为提高液力机械传动系统效率,制定了液力变矩器闭解锁控制策略。通过建立可闭锁式液力变矩器动力学模型,分析其液力、滑摩、机械这3种不同工况,然后建立仿真模型。将所建立的可闭锁式液力变矩器模型应用于某履带式工程车辆的整车动力学模型中,以该车型进行仿真。仿真计算以2挡起步,在动力性换挡策略控制条件下,对液力变矩器实施闭解锁控制,计算了2挡到6挡的加速行驶过程。计算结果表明所建立的闭解锁控制策略正确、有效。Abstract: Torque converter is a key component of hydro-mechanical transmission system. To improve the workingefficiency of hydro-mechanical transmission system,the lockup and unlock control strategy of torque converter wasdesigned. The dynamic model for lockable torque converter was established,and three types of its working condi-tions,including hydraulic working condition,frictional working condition and mechanical working condition,wereanalyzed,based on the present simulation model for torque converter. The model of lockable torque converter wasapplied to the powertrain system model of a certain tracked engineer vehicle. Under the control strategy of dynamicgear shift,the simulation model was computed from 2 nd gear and upshifted to 6 th gear. The simulation result indi-cates the lockup and unlock control strategy is correct and valid.
