| Abstract: |
| The constitutive model of EPDM sponge material was established，the simulation analysis of compression deformation of EPDM sponge auto weatherstrip was carried out by using software Abaqus，and the simulated results were verified by experimental test. The results showed that，the material parameters of the Ogden model for EPDM sponge were valid by fitting material mechanics performance test data. The result of the simulation analysis on the compression force-deformation relationship of the weatherstrip was consistent with the experimental test result. With the establishment of material model and simulation analysis on weatherstrip structure，the development cycle of weatherstrip could be shortened effectively，and the development efficiency was enhanced. |
