摘　　要：为解决"在设计阶段就能预测减振器的阻尼特性"的问题,基于Easy5软件建立减振器的数学模型并进行仿真研究。其中该模型的建立是基于对双筒液力减振器的结构和工作原理的分析,使用能描述减振器内部结构的基本参数,同时用小挠度理论对其核心元件环形节流阀片的变形进行求解。计算结果与试验结果符合较好,该模型可进一步应用于研究液力减振器的动态阻尼特性对整车动力学性能的影响。In order to solve the problem of predicting damping characteristic of the shock absorber in the stage of design,a mathematical model for the shock absorber was built and simulated using the software Easy5.The establishment of the model was based on the analysis of internal configuration and working principle of double-tube hydraulic shock absorber,then using the parameters described the internal configuration of the shock absorber,and its core element ring throttle-slice was solved using small deflection theory.The calculated results agree well with the test datas.The model can be used to study the effects of dynamic damping characteristic of the absorber on the vehicle performance.
