Abstract
Multi-stand roll forming is a process that has very complicated deformation behaviour and shows significant nonlinearity. In this paper, the sensitivity analysis of parameters for multi-stand roll forming was performed via a new booting finite element method (FEM) model. Compared with the most of simulation, the new model is more consistent with production process and can account for the effects of roll rotating speed. Based on the model, the process of an open section channel formed with 10 passes was simulated and the sensitivity analysis was conducted with orthogonal experiment design combined FEM model. The multi-stand roll forming process can be efficiently analyzed by the new booting model. And sensitivity analysis shows the hardening exponent plays an important role in controlling the quality of the products.
