Analysis and solution for wrinkle defect in the waist line of rear triangle window of body side outer panel
This paper based on the theory of stamping forming and explains the mechanism of stamping wrinkle in combination with forming limit diagram(FLD),which provides a clear idea for analyzing the wrinkledefect.Taking the side panel of an SUV model as an example,the wrinkle defects of the rear triangle window position of the waist line is analyzed,and a countermeasure to solve the wrinkling problem is found by means of AutoForm analysis software in the simultaneous engineering stage.The effectiveness of the method is verified by the product,and it provides a reference for the similar structure products or processes,and has a certain popularization and reference.
