摘　　要：基于AMESim建立了快锻压机液压系统中比例节流阀和泄压回路的仿真模型,仿真分析了不同控制信号、不同幅值以及不同临界压力条件下的主缸泄压特性,得出正弦信号能获得较斜坡信号好的泄压平稳性,正弦信号加阶跃信号能有效提高泄压快速性。The simulation model of proportional throttle valve and pressure relief return in the hydraulic system of quick forging hydraulic press have been established on the basis of AMESim. The pressure relief features of main cylinder under different control signals, amplitude, and critical pressure conditions have been simulated and analyzed. It is concluded that the sine signal has a better pressure relief stability than ramp signal. The sine signal plus step signal can effectively improve the speed of pressure relief.
