Residual stress is very important to the straightened quality of rail, this paper adopts explicit dynamics FEM to study on residual stress. We established compound roller model and calculated the residual value of heavy rail through 9 roller horizontal straightening and 8 roller vertical straightening. The reductions of straightening rollers are taken as the main effective factor to the residual stress in the straightening process. We adopt orthogonal calculation method to obtain the main effective factor to residual stress. On the base of assurance of the straightness, we obtained the optimal regulation in which the residual stress is the smallest, so the paper makes the important theoretical and actual sense to formulate the rational straightening regulation and improve the straightening quality of rail.
