摘要：

Dynamic analysis software ANSYS/LS-DYNA is applied to fluid-structure coupling simulation analysis of cartridge valve. Transient mechanical properties of cartridge valve and impact characteristics of interaction between hydraulic oil and valve spool in depressurization process were got. The result of study showed that the stability of depressurization process is related to the contacting time between valve spool and valve sleeve. The squeezing time of hydraulic oil is best not more than 0.01s. The peak impact time of hydraulic oil to valve spool in steady depressurization process is 140kN. And the maximum VonMises between valve spool and valve sleeve is 456MPa.
