In the 2nd report, a method for identifying the characteristic matrices (the mass, the damping and the stiffness matrices) was proposed by assuming that the actual experimental data included normal distributive errors. All of the measuring points must be excited one by one for input data. But it is often practically difficult to measure vibration response by exciting all of the measuring points. In this paper, a new method for identifying characteristic matrices is proposed. This method requires input data (transfer function) obtained by exciting only one measuring point. Some numerical and experimental models are examined, and the characteristics obtained by the proposed method shows good agreement with that of the examined models.
