Abstract：

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.
