The failure of top rubber structural parts has always been a challenging issue in the automotive industry.To address the durability-related cracking problem of the rear vehicle support,this study initially conducts a bench durability test on the original bracket assembly structure,revealing noticeable open cracks in the top rubber structural parts.Utili-zing tensile test data of the rubber material,Abaqus software is employed to determine parameters for an Ogden hypere-lastic constitutive model of the rubber material and subsequently optimize the structure of the top rubber.Through CAE analysis using Hypermesh and Abaqus software,an optimized bracket is tested on a bench;ultimately,the effectiveness of these improvements is verified through CAE simulation and bench test results.
