【Abstract】 This paper summarizes the highly nonlinear problems existing in the structural analysis and design of weatherstrip seals.On this basis,material constitutive models that effectively simulate the material of weather strip seals,together with the development of basic material tests and supporting test equipment,are summed up.Rules to select appropriate material models and the impact of some key issues such as the Mullins and Friction Effect on material tests and simulation analysis are fully discussed and analyzed.Combined with large-scale nonlinear finite element software,this study examines the specific application of the existing CAE technique in evaluating the actual performance of weatherstrip seals.更多还原
