| Abstract: |
| 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. |
