Characteristic matrices are the most useful parameters for being used in the field of vibration analysis because they are physical parameters and all other kinds of parameters (modal parameters, etc.) can be calculated with them. Therefore, it is important to develop the techniques to estimate characteristic matrices from experimental data. The authors already proposed a method in the second report concerning this research. It was clear that characteristic matrices were able to be identified accurately by the method. But the method needs a lot of computational time, because the algorithm are so complex and the iterative. Then, in the present paper, the authors propose a new method by which characteristic matrices can be estimated in much shorter computational time than by the old method. The dynamic characteristics of two kinds of specimens are estimated with characteristic matrices by the proposed method in order to check the accuracy and the efficiency of the method.
