Keywords： cold roll forming

Cold roll forming is a high production but complex metal forming process under the conditions of coupled effects with multi-factor.A new booting finite element method (FEM) model using the updated Lagrangian (UL) method for multistand roll forming process is developed and validated.Compared with most of the literatures related to roll forming simulation,the new model can take the roll rotation into account and is well suited for simulating multistand roll forming.Based on the model,the process of a channel section with outer edge formed with twelve passes is simulated and the sensitivity analysis of parameters is conducted with orthogonal design combined FEM model.It is found that the multiatand roll forming process can he efficiently analyzed by the new booting model,and sensitivity analysis shows that the yield strength plays an important role in controlling the quality of the products.
