非同時計測信号を用いた統合高寄与主成分モード抽出手法について

抄録

In this study, we proposed a method for obtaining high contributing whole body vibration behavior to the interior noise by integrating separated measurement vibration data set. As the candidates, two integration methods (1: Averaged response point signal, 2: High contributing principal component) were prepared and these methods were applied to a simple plate for the accuracy verification by comparing the behavior with the original OTPA PC model. As the result, High contributing principal component method was found to have an ability for obtaining correct high contributing whole vibration behavior with small scale measurement system.
