摘　　要：以履带车辆静动液辅助制动系统为研究对象,对液压泵/马达的性能进行了理论和数值分析,获得了液压泵/马达的效率曲线,在此基础上,根据液压泵/马达的效率最优原则,提出了基于液压泵/马达效率最优的再生制动控制策略。仿真结果表明,所提出的再生制动控制策略,在保证整车安全制动的前提下,使液压泵/马达工作在高效率区,实现了液压泵/马达的高效率工作,可进一步提高整车制动能量回收率。Based on the hydrostatic and hydraulic auxiliary braking system of tracked vehicle,the hydraulic pump/motor efficiency model according to hydraulic pump/motor performance analysis was set up.The optimal working line in which the hydraulic pump/motor worked at the highest efficiency level was obtained.An energy regenerative braking control strategy was proposed which could lead to the optimal matching of hydraulic coupler,hydraulic pump/motor.The simulation and test results showed that the hydraulic pump/motor could achieve efficient operation,and the energy regeneration efficiency of braking was improved obviously with the regenerative braking control strategy under the safe braking conditions.
