Abstract:
1. An inspecting method of an elastic body in a structure having two or more elastic bodies, said method comprising: observing a frequency response characteristic of said two or more elastic bodies when a vibration is applied to said structure having two or more elastic bodies; and predicting a dimension of said two or more elastic bodies based on said frequency response characteristic; wherein said frequency response characteristic is one of the characteristics selected from the group consisting of a combination of a resonance frequency Fx of one degree and at least one of resonant frequencies Fy of other degrees, one or more of frequency ratios FRxy wherein FRxy is Fy/Fx obtained by using said resonance frequency Fx of one degree and said at least one of resonant frequencies of other degrees and one or more of frequency differences FDxy (wherein FDxy is Fy-Fx) obtained by using said resonance frequency Fx of one degree and said at least one of resonant frequencies degrees.
