摘要
针对某型履带车辆中液力机械变速机构结构复杂,功能耦合的特点,基于RecurDyn及AMESim的协同仿真接口构建了机械-液压-控制耦合的联合仿真模型,利用台架试验验证了模型可信度。对其启动、换挡工况下进行仿真分析,结果说明采用液力传动技术可以增强系统起步动力性能,减小动载冲击,但在提速过程会有一定的延迟;而液压换挡缓冲回路可控制离合器结合时的缓冲压力,实现换挡过程动力的平稳过渡,有利于系统动力的平稳传递。
For the characteristics of complex structure and coupling functions in hydraulic-mechanical speed-shifting mechanism of a certain type tracked vehicle,based on the RecurDyn and AMESim simulation platform,a mechanical-hydraulic-control coupled combined-simulation model was constructed by using the software interface. The reliability of the hydraulic mechanical speed-shifting mechanism was proved by bench test and the running characteristics during start,shift and steering were analyzed. The results show that the hydraulic transmission technology can enhance the starting power performance and reduce the dynamic load shock,but there will be a certain delay in the speed increase process;and the hydraulic shift buffer circuit can control the buffer pressure when the clutch is combined to realize the smooth transition of system power during the shift process.
