| 中文摘要: |
| 以商用车底盘用膜式空气弹簧（简称膜式空气弹簧）为研究对象，对其静刚度进行有限元分析，并与试验结果进行对比。结果表明：采用流体腔法表征气囊内腔气体压力更符合膜式空气弹簧的实际工作过程；采用膜单元法和嵌入单元法对膜式空气弹簧气囊囊皮进行建模，对其静刚度曲线的整体趋势影响很小，但在大行程工况下静刚度存在差异；为了更好地反映气囊囊皮结构对膜式空气弹簧静刚度的影响，推荐采用流体腔法和嵌入单元法进行膜式空气弹簧静刚度仿真。 |
| 英文摘要: |
| Taking the diaphragm air spring for commercial vehicle chassis（referred to diaphragm air spring） as the research object，the static stiffness of the diaphragm air spring was analyzed by finite element method and compared with the test results.The results showed that using the fluid cavity method to characterize the air pressure in the airbag cavity was more suitable for the actual working process of the diaphragm air spring.Using membrane element method and embedded element method to model the diaphragm air spring airbag skin，had little influence on the overall trend of the static stiffness curve，but the static stiffness under large stroke conditions had difference.In order to reflect the influence of the airbag skin structure on the static stiffness，fluid cavity method and embedded element method were recommended for static stiffness simulation of diaphragm air spring. |
