【Abstract】 By analyzing the working process of hydraulic power system in a direct-drive hydraulic press, the pressure building-up is simulated at different load. The results show that the time of pressure building-up is a main factor affecting the forging number of press. This is a problem to take into account when designing a high-speed hydraulic press.更多还原
