| 中文摘要: |
| 介绍汽车车门门洞密封条（简称门洞密封条）的断面结构、接角结构及轻量化设计。通过非线性软件MARC分析门洞密封条结构，设计合理的门洞密封条断面结构和接角结构；采用三元乙丙橡胶密实胶或热塑性硫化胶作为接角材料，并对接角模具V字形开口角度进行调整；通过材料选择，实现门洞密封条的轻量化。优化设计的门洞密封条密封性能和外观质量均有提升。 |
| 英文摘要: |
| 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. |
