Basic point of manifold research method for rolling theory is discussed. These methods are engineering numeration, the method of slip line network, the limit analytical method, the plastic finite element method, energy method, research rolling theory with viscosity hydrokinetics, the boundary element method, the finite twig element method and the artificial neural network technic. Point out holding crux part on the whole bog of tricks. Apply range of apiece research method are analyzed and compared. The selection to embark research methods of rolling theory is to have definite referential action.
