Optimization Design of Sealing Strip Section Based on Finite Element Analysis

This paper describes the constitutive equation of rubber material, and analyzes the compression load (CLD), 3D corner deformation and lip deformation effect of the seal strip by using MARC analysis ware in the design stage. After products’ development, the test results are compared with the design analysis results. For the lip deformation of body seal and the deflection of door seal strip, using MARC software to reproduce the problem phenomenon, the improvement scheme is analyzed. We will fully explain the necessity of Finite Element Analysis in this paper.
