| Abstract: | Simulation analysis was made of stress and strain distribution of high-strength steel in the process of cold roll forming under different technical conditions via finite element software. It is found that the results of the finite element simulation of stress and strain distribution agree well with the actual situation, and among three different paths, four-path rolling is the best. It is also found that the upper rolling angle must be four degrees bigger than the forming angle, which can minimize the residual rolling stress. |
