摘要：

为了应对大吨位精冲机快速缸液压系统高压力、大流量的工况，设计了一种快速缸液压系统和分阶段PID控制方法，并在AMESim软件中建立了仿真模型，对快速缸的压力、速度、位移进行了仿真。仿真结果与精冲机样机上的实验曲线对比，滑块上死点的定位误差在0.01 mm内，仿真位移曲线与给定位移曲线之间的延时误差为0.02 s，从而验证了模型的正确性，满足了精冲工艺的技术要求。通过调整模型参数，对比位移仿真曲线，分析验证了蓄能器的设计能够使大吨位精冲机快速缸系统的运行更快、更平稳且能耗更低。

In order to cope with the high-pressure and high-flow of the hydraulic system for the large-tonnage fine blanking press, a fast cylinder hydraulic system and a phased PID control method were designed. Then, the calculated model was established in AMESim software, and the pressure, speed and displacement of the fast cylinder were simulated. Comparing with the experimental curve on the fine blanking press, the location error of slider is within 0.01 mm, and the time-delay error between the simulation displacement curve and the given displacement curve is 0.02 s. Therefore, the correctness of the model was verified, and the requirement of fine blanking was met. Furthermore, by adjusting the model parameters and comparing the displacement simulation curves, the results show that the design of accumulator can improve the operation speed of the large-tonnage fine blanking press, maintain more stable movement and decrease energy consumption greatly.
