英文摘要：

In order to study the effect of the elastic restoring valve of hydraulic shock absorber on the damping force,this study employed the ADINA software,in combination with the fluidstructure interaction theory,to construct the solid finite element model and the fluid finite element model of damping oil.Through relevant software post-processing calculation,this study obtained the indicated work and speed characteristics of the shock absorber.On this basis,the hydraulic shock absorber has been tested and verified.By comparing the results before and after the test,the results show that the established finite element mesh model is accurate and effective.
