| Abstract: |
| The cross-section structure，joint angle structure and lightweight design of automobile
doorway sealing strip （doorway sealing strip for short ） was introduced. By using the nonlinear software
MARC，the structure of the doorway sealing strip was analyzed，and the reasonable cross-section structure
and joint angle structure of the doorway sealing strip were designed. Ethylene propylene diene rubber dense
compound or thermoplastic vulcanizate was used as the joint angle material，and the V-shaped opening angle
of the joint angle mold was adjusted. Through the material selection，the lightweight of the doorway sealing
strip was realized. The appearance quality and sealing performance of the optimized doorway sealing strip
were improved. |
