摘　　要：运载火箭卫星整流罩的对接和安装需要使用高空作业车完成,持续工作时长4h以上,对高空作业车液压系统节能性、工作时长等都提出了较高要求。针对高空作业车持续作业下的发热限制和节能要求,采用了一种阀控负荷传感回路实现液压系统节能目标,建立高空作业车液压系统负荷传感阀、平衡阀、基本臂回路等的仿真模型,并对液压系统节能效果进行试验测试,验证了阀控负荷传感回路节能原理的正确性。Carrier rocket satellite fairing of docking and installation needs to be done using aerial vehicle, continue to work more than 4 hours, energy-saving hydraulic system on aerial vehicle, working hours .etc are put forward higher requirements. Based on aerial vehicle thermal limit under continuous operation and energy saving requirements, adopting a vale controlled load-sensing circuit to achieve energy efficiency goals,it is obtained by theoretical calculation that heating power and the temperature rise of hydraulic system. This paper builds simulation model of aerial vehicle hydraulic system load sensor, balance valve, the basic arm circuit, testing the energy saving effect of hy- draulic system, and verify the correctness of the energy-saving principle of the vale controlled load-sensing circuit.
