摘　　要：为了减小定量泵负载敏感系统的能耗,用二维脉宽调制转阀替代泵控系统中由负载敏感阀构成的阀组,设计了一种基于流体脉宽调制的负载敏感系统。根据该负载敏感系统的工作原理,建立了系统AMESim仿真模型,对系统的负载敏感特性和能耗进行了仿真分析,并搭建了实验平台,进行实验验证。结果表明:二维脉宽调制转阀与定量泵的组合使系统具有负载敏感特性,使得定量泵输出功率和负载消耗的功率都随着负载的变化而变化,减小了溢流损失,提高了系统的节能效果。In order to reduce the energy consumption of the load sensitive system of a fixed displacement pump,the valve group composed of load sensitive valves in the pump control system was replaced by a two-dimensional pulse width modulated rotary valve,and a load sensitive system based on fluid pulse width modulation was designed.According to the working principle of the load sensitive system,the AMESim simulation model of the system was established,the load sensitive characteristics and energy consumption of the system were simulated and analyzed,and an experimental platform was built for experimental verification.The results showed that the combination of two-dimensional pulse width modulated rotary valve and fixed displacement pump made the system load sensitive,so that the fixed displacement pump output power and load consumption power changed with the load,which reduced the overflow loss and improved the energy saving effect of the system.
