摘　　要：把水压机活动横梁假设成一交叉梁系 ,对其做了弹塑性有限元分析 ,导出了部分节点弯矩超过弹性极限时的梁单元刚度矩阵 ,讨论了计算方法的收敛性。The paper has supposed the movable girder frame of water press to be a cross bar system and made an elasto plastic analysis of that part using finite element method.This paper has also derived the unit stiffness matrix of bar element on which the moment of some nodes is over the elastic ultimate moment and discussed the convergent properties of computing method.
