摘要/Abstract

摘要： 以某型液力传动车辆为研究对象，为提升液力工况向机械工况过渡过程中闭锁品质，尤其是减小车辆闭锁过程中产生的冲击，对闭锁离合器的动态缓冲特性开展理论和试验研究。建立具有闭锁功能的液力变矩器及其主、被动端动力学系统仿真模型，分析闭锁过程的快速充油、缓冲升压及阶跃升压各阶段对闭锁品质的影响，采用最优拉丁超立方试验设计方法，对缓冲升压阶段的缓冲斜率进行优化，通过所构造的闭锁品质评价函数比较优化前后冲击度、滑摩时间及滑摩功等品质评价参数，并搭建闭锁特性试验验证台架对优化前后闭锁品质进行验证。研究结果表明，所建立的动力学系统仿真模型能够对动态闭锁过程进行准确预测，优化后闭锁品质较优化前有明显改善，冲击度显著降低，基于闭锁品质评价函数的品质优化方法能够为液力传动车辆的闭锁特性的设计和研究提供理论参考。

Abstract: The dynamic cushioning properties of locking clutch for a hydrodynamic transmission vehicle are studied to improve the locking quality in the transition process from hydrodynamic transmission operating condition to mechanical condition, in particular, to reduce the impact in vehicle's locking process.The dynamic models for hydrodynamic torque converter with locking function and its input and output components are established. And the effects of oil-filling, buffer boosting, and step boosting on the locking quality during locking are analyzed. The optimal Latin hypercube design method is used to optimize the buffer slope in the buffer boost stage. The quality evaluation parameters, such as jerk, sliding time and sliding work, before and after optimization are compared using the proposed locking quality evaluation function. A locking characteristic test verification bench was built to verify the locking qualities before and after optimization. The results show that the proposed dynamic system simulation model can be used to accurately predict the dynamic locking process. The locking quality after optimization is significantly improved compared with the result before optimization, and the impact is significantly reduced. Key
