Elastic-Plastic Finite Element Analysis of the Roll Forming Process for an Automotive Part of High Strength Steel
고강도강 자동차 부품의 롤 성형 공정의 탄소성 유한요소해석
Abstract
A roll forming process is developed for an automotive part of high strength steel. Forming rolls are designed through the plane strain elastic-plastic finite element analysis to estimate the springback. It is assumed that the process can be approximated as a series of multi-step bending processes. Then the 3D elastic-plastic finite element analysis with the solid element is carried out for the designed roll forming process. The prototype roll forming machine and the forming rolls are made and the experiments are carried out. The results of the analysis and the experiments are compared.
