| 摘 要： | 目前空气弹簧已广泛应用于车辆悬架系统中。车辆动力学性能主要取决于悬架参教的匹配。悬架参教的精确性将直接影响车辆行驶的平稳性。基于热力学理论和气体状态方程式，建立了带附加气室的空气弹簧的统一力学模型，对其数学模型进行了求解，得出了其瞬态响应和稳态响应的理论值，求出了空气弹簧的自振频率和粘滞阻尼系数。为设计制造空气弹簧奠定了一定的理论基础。

| Abstract: | At present the air spring has been widely used in vehicle suspension systems. It is found that the vehicle system dynamics is mostly determined by the matching of the suspension parameters,and that the precision of theses parameters affect the ride comfort directly. Based on the theory of thermodynamics and polytropic process state equations,the uniform dynamical model of the air spring with an auxiliary air chamber is established. Then the solution of this model is presented,and the free vibration and forced vibration response character are also researched. At last the natural frequency and the damping coefficient of the air spring are gained,which is very useful to the design and modification for air spring. |
