摘要：

针对某厂12500kN/3500kN组合式高速油压机的快速冲盂过程减速困难问题，利用AMESim建立其仿真模型，并对其冲盂过程进行仿真研究。改进了原系统单独凭借减小回油路上流量阀的开口度来减速的控制方式，提出一种通过协调控制匹配供油泵数量与流量阀的开口度的减速方案。仿真结果表明此种减速方案可实现组合油压机较平稳减速，并减小了压机振动。

To solve deceleration difficulty in punching process of a 12500 kN/3500 kN combined hydraulic press, the simulation model based on AMESim as well as the simulation study on punching process were both developed. The control way of decreasing the opening of flow valve only was improved, and then a kind of deceleration strategy that coordinates supply pump numbers and the opening of flow valve was proposed. The results show that the strategy can guarantee combined hydraulic press to decelerate stably and reduce the vibration of the press.
