摘　　要：针对传统阀后补偿负载敏感液压系统较低压力侧压力补偿阀工作时温升高、使用性能及寿命低等缺点,提出一种两个液阻并联分流的改进阀后补偿负载敏感液压系统。利用AMESim仿真软件建立该系统的模型并进行仿真研究。结果表明:在相同工况下,改进后的负载敏感系统能够根据需要灵活降低单个压力补偿阀上的能量损耗,提高系统及元件的性能和使用寿命。所得结论为阀后补偿负载敏感液压系统的优化设计提供了参考。Aiming at the disadvantages of the traditional after-valve compensation load sensitive hydraulic system with lower pressure side pressure compensation valve,such as high temperature rise,low service performance and low service life,an improved after-valve compensation load sensitive hydraulic system with two liquid resistance shunt in parallel was proposed.AMESim simulation software was used to build the system model and the simulation analysis was carried out.The results show that under the same working conditions,the improved load sensitive system can flexibly reduce the energy loss of a single pressure compensation valve,and improve the performance and service life of the system and components.The conclusion provides reference for the optimal design of the after-valve compensation load sensitive hydraulic system.
