摘　　要：叙述了罚单元法和罚单元刚度矩阵的推导过程。列举了应用罚单元法处理旋转对称子结构边界位移协调和不同类型单元连接点位移协调的实例 。Penalty element method and derivation of penalty element stiffness matix are described. The method can be used not only to solve the displacement conformance of cyclosymmetrical substructures, but also to determine the substructure constaints. The relative calculations are taken as examples to show the validity and the rationality.

关 键 词：旋转对称子结构 罚单元 线性约束 刚度矩阵
