摘　　要：为了研究液压减振器弹性复原阀对阻尼力的影响,使用ADINA有限元软件,并结合流固耦合相关理论,构建了固体有限元模型及减振油流体有限元模型。通过相关软件后处理进行计算与求解,获得了该减振器的示功特性和速度特性。在此基础上,对该型号液压减振器进行试验验证,并将前后结果进行对比,结果表明所建立的有限元网格模型准确有效。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.
