Finite Element Model Updating of Damped Structures Based on Pretreatment Technique

摘要：

Based upon pretreatment technique, a method for modifying dynamical model of damped structures is proposed in this paper. Updating equations about the mass, stiffness and damping matrices of the structure are constructed at first. By means of the orthogonal conditions and the characteristic equations of complex modal theory, modified Structural parameters are solved by using of pretreatment technique.Numerical example has shown that the presented method is quite accurate and efficient.
