Abstract: PROBLEM TO BE SOLVED: To make it possible to approximate and estimate the initial value of a mode-attenuating ratio simply from an MIF by operating a mode indicating function(MIF) with an operating device by using the obtained frequency response function(FRF) data. SOLUTION: The exciting force of a percussion testing hammer 2 for the certain position of a test piece 1 is detected by a force detecting sensor 3.

Then, high-speed Fourier transformation is performed, and the FRF data are obtained from the experiment data. The MIF data are operated by using the FRF data. From the MIF data obtained in this way, the initial values of the natural angular frequency and the mode damping ratio are obtained.  Furthermore, the FFT operating device 5 identifies and operates the mode characteristics by using these natural angular frequency, the mode damping ratio and the FRF data, and the accurate characteristic frequency, the mode dampling ratio and the mode characteristic data data can be obtained. Thus, the initial value of the mode damping ratio can be simply approximately and estimated.
