Abstract

A method for the modifying structural dynamical model is proposed in this paper.Based upon the orthogonal equation of model theory,updating equations about the mass and stiffness matrices of the structure are constructed at first and then,a stable iterative method is presented to solve the modified structural parameters.A numerical example is given.A better agreement between updating and experimental model parameters is obtained.
