| 摘 要： | 为实现重物势能回收再利用，以蓄能器为储能元件，设计闭式液压系统的节能回路。引入电磁比例减压阀，研究以蓄能器压力、外负载及速度为判断参数的控制策略。建立AMESim-Simulink联合仿真模型，分析回路压力与流量特性。仿真结果表明，该控制策略可使节能回路中的压力与流量稳定，并满足外负载与速度变化的需求。

| Abstract: | In order to carry out to save and reuse gravitational potential energy of load, an energy-saving hydraulic loop with an accumulator for closed-loop system is designed. The control strategy based on accumulator pressure, load and velocity is analyzed for the loop with electromagnetic proportional pressure relief valve. Also the AMESim-Simulink co-simulation model is built to analyze the character of the loop pressure and flow rate. The simulation results indicate that the control strategy can ensure steady pressure and smooth flow rate of the loop, and can meet various load and velocity requirement. |
