| 摘 要： | 针对履带车辆下长坡制动过程中不同制动力的分配关系，在液力减速器和整车下坡动力学分析的基础上，研究了基于液力辅助制动的履带车辆下长坡制动控制策略，建立了基于SIMULINK的履带车辆整车动态仿真模型，对液力减速器的持续制动性能和控制策略的有效性进行了仿真．结果表明，车辆下坡持续制动时，适时应用液力减速器，能够有效分流整车制动功率，明显降低机械制动器的工作负荷，满足整车安全恒速下坡的要求．

| Abstract: | In this paper, the control strategy of hydraulic retarder auxiliary braking for tracked vehicle on long downhill is studied. With the dynamic-analysis of hydraulic retarder and total vehicle on downhill, the distribution of hydraulic braking force and mechanical braking force is discussed. The whole vehicle dynamic simulation model is built based on Matlab/SIMULINK,and coordinated simulation research is carried out to analyze the continual braking performance. The simulation results show that when hydraulic retarder continual braking is used opportunely,it can satisfy the demands of tracked vehicles to safely travel on sloping hillside with constant velocity, and it can prolong the usage period of mechanical brake. |
