摘要 有限元模型修正是一类特殊的二次反特征值问题.我们将有限元模型修正看成二次规划问题来解决,并采用非线性Gauss-Seidel方法来求解其相应的Lagrange对偶函数.最后,给出的数值实验说明方法的有效性. Finite Element Model Updating Problem is a special inverse quadratic eigen- value problem. In this paper, the author consider the problem as a quadratic programming problem, and propose the nonlinear Guass-Seidel method to solve it. Numerical experi- ment show the efficiency of the method.
