Abstract: In this paper, boundary element method is introduced to PC-minicomputer to calculate the displacement field and the stress field on the stands of 1700mm continuous cold rolling mills in WUHAN Steel Works. Through the calculation the new structure feature of the stands can be seen clearly. The result of the calculation shows that whether the calculating result is correct of not can be judged by whether the forces and moments on the boundary face can satisfy the balance condition of the force.
