The use of approximate Hessian matrix iteration in structural optimization can obtained optimization results. At the same time, the second order approximation expansion of structural parameters can be obtained, second-order constant, also know as Hessian matrix is among them. To reversely calculate structural parameters by using second-order approximate expression of the gradient matrix and Hessian matrix for optimization function in identified optimization results. As a result of the second-order method, structural parameters anti-optimization calculation is more precise,through the cantilever plate stiffener structure calculations, the effectiveness of this method is showed.%利用结构优化中海森矩阵的近似迭代方法可以得到结构优化结果的同时,还可以得到结构参数优化函数的二阶近似展开式,其中二阶常数项也就是海森矩阵.利用优化函数的梯度阵和海森矩阵建立函数的二阶近似表达式在已确定的优化结果反向计算结构参数.由于采用的是二阶计算方法.结构参数的反优化计算更加精确,通过对悬壁板加强筋结构的计算,证明了这种方法的有效性.
