SOUNDNESS DEGREE DIAGNOSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To specify a place where a structure is changed by applying vibration in a fixed frequency region and analyzing mode of the structure. SOLUTION: Vibration is locally applied to the structure. A soundness degree diagnosis device is provided with a changed condition inference part for evaluating how vibration mode obtained by measuring response for the vibration of the structure is changed from vibration mode when the structure is sound and inferring the place where the structure is changed.
