英文摘要：

Taking into consideration the complex contact between seal material and window,the functional equivalent principle was adopted by using non-linear spring sets for modeling non-linear constraint,so that the whole complex constraints between seal and glass were discreted by finite spring sets.For the double curvature window,its boundaries and motion path were determined by free surface reconstruction.In addition,using solid modeling and driving function,a 3Dautomotive window sealing dynamics was constructed.The functional relation between dynamical parameters such as friction,time and mass was accomplished,which supported the new window sealing optimization with proper slide and balance friction.
