摘　　要：为了对履带车辆制动能量进行回收和再利用,根据某型履带车辆传动系统特点,建立了履带车辆液压储能式制动能量再生系统,分析了系统的工作原理,介绍了系统的工作模式。基于踏板行程逻辑门限值的模糊控制策略,分别建立了履带车辆制动工况和驱动工况控制策略,构建了两种工况下的控制系统Simulink模块。对履带车辆辅助制动和辅助驱动工况进行了仿真分析,得出车速、系统压力和燃油消耗率等参数的变化规律。设计并建立了系统模型实验台,对制动能量回收和再利用过程进行了原理性实验,计算了液压储能式制动能量再生系统总效率。通过比较仿真和实验结果,分析了影响系统总效率的因素,得出系统的实际可行性等结论。In order to recover and reuse braking energy of tracked vehicle, according to the drive system characteristics of a tracked vehicle, the hydraulic regenerative braking system was introduced. Then, the working principle and the pattern were analyzed. The control methods of braking process and driving process based on fuzzy control strategy of pedal journey logic threshold were put forward, of which simulink modules were set up.Through simulating on the two processes, the varying disciplines of speed, system pressure and fuel consumption rate were achieved. Finally, the model test bed of the system was built up, and the total efficiency of hydraulic regenerative braking system was calculated. By comparing simulation results with experiment results, the influencing factors on total efficiency and the practical feasibility of the system were analyzed.
