Abstract：Aiming at the installation clearance of door outer seal in the assembly process， the 3D simulation model was established by using MSC and Marc， the highly nonlinear analysis software. And its causes of the installation clearance between the door outer seal and the sheet metal were analyzed. And then through the optimization of the clearance between the installation holes， this clearance problem was solved.

Key words：door sealing， installation clearance， finite element analysis， optimization

車門密封條是安裝在車門鈑金上，在車門關(guān)閉時(shí)與車身側(cè)圍發(fā)生接觸變形，起到緩沖作用;同時(shí)阻隔車輛內(nèi)部與外部空氣流通，起到防風(fēng)、防塵、防水和隔聲等作用。（剩余1999字）
