| 中文摘要: |
| 运用ABAQUS分析软件建立膜式空气弹簧的有限元模型，通过仿真计算获得负荷-横向位移曲线，研究初始内压和帘线间距对膜式空气弹簧横向刚度的影响。结果表明，空气弹簧的横向刚度随着初始内压的提高而增大，同时由于空气弹簧膨胀造成帘线间距增大，引起横向刚度降低。本研究为膜式空气弹簧设计中合理选择初始内压和帘线间距提供了参考。 |
| 英文摘要: |
| The finite element model of rolling lobe air spring was established by ABAQUS analysis software，the load lateral displacement curves were obtained through the simulation and the influence of initial internal pressure and cords distance on the lateral stiffness of rolling lobe air spring was studied.The results showed that，with the increase of initial pressure，the lateral stiffness of the air spring increased，while the increase of the cords distance caused by the air spring expansion reduced the lateral stiffness.This study provided references for the design of internal pressure and cords distance during air spring design. |
