Abstract：In order to improve the straightening quality, the curve shape and straightening precision of double curve shape and three curvature shape was calculated by Matlab and roll shape was drawn according to the theory of elastic and elastic-plastic of bar. Considering the deformation of elastic plastic bar, the elastic plastic model of the specific two-roller straightener was built by means of finite element analysis software MARC. The working process of the two-roller straightening was simulated and the changing parameters were analyzed during the process of straightening. Through contrasting the straightening results, it was concluded that the straightening precision of curvature shape is better than that of double curvature shape.
