基于密封条反弹力的汽车车门钣金预弯设计分析

The analysis of the pre-bending design on the Door Panel based on the rebound force of the weather strip

在汽车车门钣金的结构设计中,需考虑车门上窗框在密封胶条反力作用下的变形量。在冲压模具制造之前,设计窗框预弯曲以抵消或减小窗框变形量,或者在焊接夹具上设计矫形调节余量,以满足车身外观面差要求。文章据此详细阐述了车门预弯设计的方法思路及某车型应用实例。

In the structure design of door panel, the frame should be considered in deformation under the reaction of weather strip.Before making stamping die, we should design the pre-bending on the frame to offset or reduce the deformation, or design corrective adjustment in the welding jig, to meet the requirements of the body exterior surface offset.This paper expounds on the method of pre-bending design on the door panel and application at the model of practical examples.
