| 摘 要： | 针对冲击隔离研究需要，建立了带辅助气室橡胶空气弹簧的物理模型。考虑到空气弹簧承载力和囊内容积与橡胶囊形变的关系难以用数学解析式描述，系统冲击响应采取数值计算方法，该方法将模型控制方程转化为差分形式，并在方程数值求解中嵌入橡胶囊形变的有限元分析。利用上述解法，对橡胶空气弹簧冲击隔离特性进行了研究，并分析了有关影响参数。

| Abstract: | The theoretical model for a rubber-air spring with auxiliary chamber is establishted to analyze its shock-absorbing performance. The solution of the system shock response resorts to numerical methods because the relations of the spring load and the inside volume with the deformation of rubber bladder can not be described with analytical equations. To perform the numerical calculation, the system control equations are transformed into difference equations, and the finite element analysis of the rubber bladder is employed in the process. Based numerical results, the shock absorbing performance of a rubber air spring is studied, and the influence of related parameters are analyzed. |
