【摘要】 为了使结构分析模型更好的逼近实际结构，本文讨论了介于刚性连接与铰连接点之间的弹性连接的性质，给出了弹性连接杆单元的刚度矩阵；提出了最佳连接的概念，并将节点柔性系数作为设计变量，建立了弹性连接杆系的结构优化模型。更多还原

【Abstract】 The qualities of elastics nodes to connect POle systems are discussed, the stiffness matrix of the element connected by elastic nodes and conception of an optimal node is presented. With flexibility coefficients considered as design variables, the model of structural optimization of the POle systems connected by elastic nodes is also built up.更多还原
