Abstract:
      Abstract:Firstly,the mechanical performance tests of ethylene-propylene-diene rubber dense compound and sponge compound of tailgate sealing strip for passenger car were carried out,the constitutive models of two materials were determined,and then the compression process of the tailgate sealing strip was simulated and analyzed by the finite element analysis software Abaqus. The results showed that the stress,strain and strain energy of the sponge tube of the tailgate sealing strip were relatively high,and the strain and strain energy in the contact part of the sponge compound and dense compound were also high. The relationship curve between the compression force and compression amount of the tailgate sealing strip obtained by simulation analysis fitted well with the experimental results,the average error of the test compression force was within 10%,and the simulation and test results were in good agreement.
