Abstract
In this study, we verified accuracies of two kinds of transfer path analysis methods by performing a simple structure test. Inverse matrix method using transfer functions and principal component analysis method using only running data were examined. As the result of experiments, the accuracies of these methods were clarified to drop occasionally in some frequencies, but the frequencies are different each other. These results indicate that it is necessary to select suitable transfer path analysis method according to the target frequency for obtaining contribution of noise and vibration accurately.
