Solution to real quadratic model updating problems with incompletely measured data and no spillover
摘要
Abstract
This paper aims to solve the real quadratic model updating problems with incompletely measured data and no spillover which usually appears in vibration engineering.By using the method of partitioned matrix and the columns of the matrix,the solvable conditions and parameter expression of the solution for the real quadratic model updating problem are proposed and an algorithm is constructed for the solutions of the problem.Finally a numerical example is given to illustrate the effectiveness of the proposed method.It shows that the real quadratic model updating problems can be updated by part of the spectral information measured,at the same time,remains the rest spectrum information unchanged.关键词
