The reliability of door sealing plays an important role in maintaining the quality of vehicle noise, vibration, and harshness (NVH). To improve the reliability of door sealing, a novel sealing process has been proposed. The factors influencing the door sealing quality have been investigated. The relationships between the peeling force, peeling speed, and peeling time have been calculated using the five-variable rheological theory. The maximum stress versus time curve and the distribution of stress and strain at the moment of debonding have been obtained by nonlinear solid cohesive coupling dynamics simulation. The rolling process of the door sealing strip has been developed, and automatic rolling equipment for door sealing has been designed and manufactured. The factors influencing the peeling force have been determined by a peeling test of the door sealing strip. The results show that the peeling force increases with an increase in the peeling speed and time. The C-shaped structure at the front end of the base material during the stripping process makes the peeling angle sharp. In addition, the uneven stripping speed causes the stripping line to become irregular. The peeling force increases with the increase in rolling pressure and failure time. The optimum rolling pressure was 70 N/m² and the optimum aging time was 24 h.

车门密封的可靠性对于保持车辆噪声、振动和平顺性 (NVH) 的质量起着重要作用。为了提高门密封的可靠性，提出了一种新的密封工艺。对影响门封质量的因素进行了研究。使用五变量流变理论计算了剥离力、剥离速度和剥离时间之间的关系。通过非线性固粘耦合动力学模拟得到最大应力随时间变化曲线以及脱粘时刻的应力应变分布。开发了门封条卷制工艺，设计制造了门封条自动卷制设备。影响剥离力的因素已通过门密封条的剥离试验确定。结果表明，剥离力随着剥离速度和剥离时间的增加而增加。剥离过程中基材前端的C形结构使剥离角度锐利。另外，不均匀的剥线速度导致剥线变得不规则。剥离力随着轧制压力和失效时间的增加而增加。最佳轧制压力为 70 N/m 剥离力随着轧制压力和失效时间的增加而增加。最佳轧制压力为 70 N/m 剥离力随着轧制压力和失效时间的增加而增加。最佳轧制压力为 70 N/m²，最佳老化时间为24小时。
