车门密封条(auto door rubber seal strip)主要用于车门的固定、防尘及密封。主要由具有良好弹性和抗压缩变形、耐老化、臭氧、化学作用、较宽的使用温度范围(-40℃~+120℃)的三元乙丙橡胶(EPDM)橡胶发泡与密实复合而成,内含独特的金属夹具和舌形扣,坚固耐用,利于安装。 主要应用在车门门扇门框、侧面车窗、前后档风玻璃、发动机盖和行李箱盖上,起到防水、防尘、隔音、隔温、减震、装饰等作用。
为了解决某轿车车门密封条压缩负荷超标的问题,采用非线性有限元软件MSC。
In order to solve the problem of door weather strips which compression load are out of their standard, the nonlinear finite element software, MSC.
在汽车的车门,车窗和天窗边缘上,都有密封条的存在。
In the car door, Windows and skylights edge sealing strip, are there.
为此,笔者建立了基于直接约束法的接触算法,利用数值方法对密封条与车门之间的接触特性进行了分析研究。
Therefore, the contact algorithm is established based on direct restriction and the contact characteristics between the seal and the door are studied using numerical method.
