液压冲床油缸泄漏研究与仿真

Simulation and Study of Hydraulic Punching Machine's Hydro-cylinder Leakage

为解决液压冲床工作中辅助液压缸泄漏问题,对其液压系统回路进行了分析,得出了辅助液压缸泄漏是由于电磁换向阀换向时间设置不合理,致使液压缸中压力过高所造成的结论。通过运用AMESim仿真软件对液压系统回路进行仿真,验证了结论的正确性,并在此基础上提供了合理的换向时间,为实际问题的解决提供了理论依据。

To solve the problem of hydraulic punching machine＇s hydro-cylinder leakage,the hydraulic punching machine＇s hydraulic circuit was analysed,and then having the conclusion that high pressure result in leakage of the assistant hydro-cylinder.Then the simulation of the hydraulic system is achieved using the AMESim.The simulation proved the validity of the conclusion and a solution is brought forward,that provide a foundation for the leakage problem solve.
