摘　　要：针对300MN模锻水压机加压-提升过程中提升管道液压冲击较大的问题,建立水压机水路系统的AMESim仿真模型,设定加压-提升过程主分配器轴角度由170°～5°的变化时间t为1、0.5、0.3、0.1s,仿真分析提升管道中液压冲击值为27.8、89.6、100.5、146.8bar,并得出加压-提升过程主分配器轴角度由170°～5°的变化时间、提升管道压力、以及工作缸压力之间的关系。分析结果表明:加压-提升过程主分配器轴角度由170°～5°的变化时间缩短将使工作缸卸压不充分,引起提升管道较大的液压冲击。Water hydraulic simulation model based upon AMESim software was established to analyze hydraulic impact in lifting pipe of 300MN die forging hydraulic press. The operating times of distributor＇s shaft changing from 170°to 5°were set to ls ,0. 5s, 0. 3s, and 0. 1 s, then hydraulic impact results of 27.8bar,89.6bar, 100. 5bar, 146. 8bar were obtained. In addition, the relations among operating time, pressures in lifting pipe and in main cylinder were demonstrated in the form of curves. The analysis results show that the insufficient unloading in main cylinder is caused by the short operating time, therefore, the water hydraulic impact in lifting pipe is great.
