摘要

To improve the accuracy of roll flattening calculation based on semi-infinite body model, a more accurate roll flattening model is proposed in this paper, which is derived basing on boundary integral equation method. The lateral surface displacement decay functions are established. Based on the boundary integral equation method, the numerical solution of the finite length semi-infinite body under the distributed force is obtained and verified by Finite Element Method (FEM). Based on the new model, the error of semi-infinite body model is analyzed in different length-diameter ratio and non-contact barrel length. Quantitative relationship and the scope of semi-infinite body model are obtained.
