摘　　要：针对装车过程中轿车车门玻璃导槽密封条弯曲唇边起皱问题,利用非线性有限元分析软件MSC.Marc建立密封条三维仿真模型,分析密封条弯曲唇边起皱原因,并对密封条结构进行优化。通过优化唇边结构及调整唇边厚度、弧度,密封条弯曲唇边不再出现起皱现象,且密封条密封性能满足要求。To aim at problem of wrinkling for the lip of car door glass run channel weatherstrip which was bending during loading process,the three-dimensional simulation model of weatherstrip was built by using the nonlinear finite element analysis software MSC. Marc. The reasons of wrinkling for weatherstrip blending lip was analyzed and its structure was optimized. By optimizing the structure and adjusting thickness and radian of the lip,the wrinkling of the weatherstrip bending lip didn’t occur,and sealing performance of the weatherstrip could meet requirements.
