摘要 利用BFGS拟牛顿法的局部超线性收敛特征,提出了基于此方法的结构拓扑修改静态重分析算法。特别是根据初始结构分析结果,构建了三种拓扑修改形式的BFGS修正迭代阵-近似Hesse矩阵逆的初始迭代矩阵的设置方法。与随机或一般指定初始迭代阵取为单位矩阵的BFGS算法相比较,应用此特殊选定的初始点,进行BFGS算法求解修改后结构的响应值能显著降低计算成本,计算结果验证了该算法的正确性和有效性。 A new method for the structural static reanalysis of the topological modification was presented using the superlinear convergence property of the BFGS quasi-Newton algorithm.According to the analysis results of the original system,the starting iterative matrixes of the BFGS modification iterative matrix-approximation inverse Hesse matrix for all three cases of modification corresponding the number of DoF is unchanged,decreased,or increased were set.Compared with the BFGS algorithm with traditional random se...
