Abstract

The Vibration Intensity (VI) method is one of the techniques to visualize vibration transmission paths. In actual structures, multiple waves exist at the same time because of reflection waves at boundaries or multiple excitation sources. If VI method is applied to the vibration field with multiple waves, VI method may detect different vibration energy flow from vibration energy flow in actual phenomena. The purpose of the present research is to investigate the influence of superposition of multiple waves on VI measurement in simple flat plate by FEM analysis.
