摘要: 本文首次用边界元法在PC微型机上计算了武钢1700冷连轧机机架的位移和应力场,弄清了该机架新结构形式的特点。从计算结果中得知,边界面力与力矩是否满足力平衡条件可作为检验计算结果是否正确的判别条件。

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.
