| 中文摘要: |
| 针对机场地面服务车辆EPDM缓冲器，开展EPDM材料的Yeoh，Mooney-Rivlin和Ogden超弹性本构模型拟合分析，并选用二阶Ogden模型（N＝2）进行EPDM缓冲器的压缩试验与仿真分析。结果表明，采用二阶Odgen模型拟合EPDM材料的应力-应变性能效果最好，EPDM缓冲器的压缩载荷-位移仿真曲线与试验曲线几乎一致，验证了本构模型和仿真分析的有效性。 |

| A fitting analysis of Yeoh，Mooney-Rivlin and Ogden hyperelastic constitutive models of EPDM materials of EPDM buffers for airport ground service vehicles was carried out.The second-order Ogden model（N＝2）was selected for the compression test and simulation analysis of EPDM buffers.The results showed that，the second-order Ogden model provided the best fitting effect for the stress-strain performance of EPDM materials，and the compression load-displacement simulation curves of EPDM buffers were almost consistent with the test curves，verifying the effectiveness of the constitutive model and simulation analysis. |
