摘要: 本文将接触区域的非嵌入条件作为惩罚项引进接触系统的总势能之中,使原来的约束变分问题转化为罚优化问题,然后用子结构有限元法进行求解。这种方法的优点是只需要对节点位移向量进行求解与判断,而不必顾及接触反力,因此计算量相对减少。

Abstract: In this paper the no-interpenetration condition between the two structures is treated as a penalty term and then the cons-trained variational problem of the contact system will be transformed into a penalty-optimum one in which the substruction finite element analysis is applied The advantage of the method is that the iterative procedure will be only related to the displacements of the nodes and be irrelative to the nodal forces therefore the calculator time is reduced relatively.
