Modeling of ThePress Drive System and Dynamic Performance Analysis for Huge Die-forging Press

采用解析法建立大型模锻压机驱动系统的仿真模型,重点分析了泄漏系数、粘性阻尼系数、油液体积弹性模量等因素对驱动系统低速稳定性的影响,从而得到了这些参数对锻压机的影响规律,并提出了解决办法,来提高大型模锻压机驱动系统的低速稳定性。

In this paper,analytic method is adopted to establish the simulation model of large forging press drivesystems,analyses the leakage coefficient,viscous damping coefficient,the oil volume factors such as elastic modulus influence to the stability of low speed drive system,it is concluded that these parameters influence law,finallythis paper puts forward some feasible measures to these rules,in order to improve the low speed stability of thelarge isothermal forging press system.
