VIBRATION ANALYSIS APPARATUS, AND AUTOMATIC DETECTION METHOD OF ANALYSIS SECTION IN VIBRATION MEASURING USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a vibration analysis apparatus for easily, rapidly, and accurately estimating a structure to be measured by automatically removing a part, where noise is contained, in measuring vibration signals and analyzing a part, where no noise is contained, in the measuring vibration signals, and to provide an automatic detection method for an analysis section in vibration measuring by using the vibration analysis apparatus.;SOLUTION: While a vibration generating means (exciter 3) applies vibration at a specific oscillation frequency to a measuring target (for example, ground 1) for vibrating the measuring target. the vibration of the measuring target is measured by a vibration measuring means (vibration measuring apparatus 4) for outputting a measuring vibration signal, a part having a noise vibration signal exceeding a specific level is removed from the measuring vibration signal by an analysis means (vibration analysis means 5) as a noise removal vibration signal, and then the noise removal vibration signal is analyzed to estimate the structure to be measured.;COPYRIGHT: (C)2005,JPO&NCIPI
