摘　　要：通过对20MN下拉式快锻压机及对液压系统动载分析,介绍了快锻液压机组设计中动载因数的重要性;就如何降低液压冲击及振动提出了分析方法,尤其是分析了液压瞬变与流体在管道内的振动对机械系统振动的影响;提出了快锻液压机组设计中降低动载因数应遵守的准则。分析研究结果对液压系统设计中对泵、阀、管道等组件单元的选型与计算具有指导意义。The importance of dynamic load factor in design of the high-speed hydraulic forging press was introduced through the dynamic load analysis for 20 MN pull-down type high-speed hydraulic forging press and its hydraulic sys- tem,The analytical method for how to reduce the hydraulic impact ~ vibration was presented. The effect for the me- chanical system vibration was especially analysed when the hydraulic transient and the fluid were vibrating in the pip- ing. The criterion for the reducing dynamic load factor on the design of high-speed hydraulic forging press was provid- ed. The analysis and research results have the guidance means for the model selection and calculation for pump, valve, piping and etc. in the hydraulic system designing.
