A Numerical Analysis on Web-Warping and Profile Accuracy in the Flexible Roll Forming of AHSS

摘要：

　　Flexible roll forming is a new sheet metal forming technology that allows the manufacture of materials with high strength to complex and weight optimised components and therefore represents a cost effective alternative for the manufacture of automotive parts from advanced high strength steel (AHSS).Web-warping as a critical shape error limits the application of the process in automotive manufacturing.This paper investigates numerically the effects of parameters of flexible roll forming process on the web-warping defect and profile shape accuracy.The results show that,process design parameters significantly affect web-warping and profile accuracy in flexible roll forming and that compared to Mild steel (MS),AHSS material can show superior performance with respect to profile shape accuracy.
