A Study on Vibration Power Flow of 2-Dimension Structure Travelling from the Source
진동원으로부터 전달되는 2차원 구조물의 진동파워흐름에 관한 연구
Abstract
To control the vibration and sound of structure, it is important to analyze the dynamic action of structure. And through those analysis, the vibration source and the flow path is understood. To grasp that, when the two-dimension plate structure is shaken by a harmonic point excitation with the natural frequency using the finite element method, this paper presents the relation between vibration power flow and mode shape. As those results present to vector flow, the vibration power flow is visualized.
