摘要:针对泵控压机缷压过程中的压力冲击问题,首先对其机理进行了研究,分析了管道和
油液对压机冲击的影响,管道越长内径越小压力冲击越大,油液有效体积弹性模量越小粘度
越大压力冲击越大。通过建立主要元件与系统的 AMEsim 仿真模型,对泵控压机系统进行
仿真研究,验证了缷压过程中管道、油液对压力冲击造成的影响。提出了改善管道和油液条
件有助于减小压力冲击。

Abstract: To analyze the impact problem during the pression process in pump-controlled
press, the paper first studies its mechanism as well as oil and pipeline’s influential properties on
the shocks (. the longer pipeline or the smaller inside diameter is, the greater pressure impact
will be; the smaller the effective oil modulus of volume elasticity or the larger oil viscosity is, the
greater pressure im
