摘要
建立三元乙丙橡胶(EPDM)海绵本构模型,采用Abaqus软件对其车门密封条压缩变形进行仿真分析与试验验证。结果表明,采用材料力学性能试验数据拟合的EPDM海绵的Ogden模型材料参数有效,密封条压缩力-形变的仿真分析结果与试验验证结果吻合。通过建立材料模型和对密封条结构进行仿真分析,可有效缩短橡胶密封条开发周期,提高开发效率。
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.
