Flexible roll forming of an automotive component with variable depth
conference contribution
posted on 2016-01-01, 00:00 authored by Buddhika Abeyrathna, Bernard RolfeBernard Rolfe, L Pan, R Ge, Matthias WeissMatthias WeissThis work is a first comprehensive study of the FRF of high strength structural components with variable depth. For this, the FRF of an automotive bumper section is analyzed numerically using the commercial software package COPRA® FEA RF. A detailed analysis of the distribution and history of plastic strain in longitudinal, transcerse and thickness directions is performed and related to the shape defects observed in the proecss. The analysis shows that when forming variable depth components, zones of compressive longitudinal strain exist that lead to wrinkling defects. These can be reduced by applying additional flange contact during the operation. In general the current work suggests that the FRF of high strength components with variable depth is possible and can compete with other forming methods currently used in the automotive industry.
