Wave Transmission Approach of Coupled Plate Structures through Non-conservative Joints for Power Flow Analysis

파워흐름해석을 위한 비보존 조인트로 편성된 평판 구조물의 파워투과반사계수 해석

The attenuation of waves transmitted through non-conservative joints that are shown in many paractical structures, is affected by the impedance and the orientation of the joint. In this paper, the joints between plate structures are assumed to be modeled as linear spring-dashpot systems and the transmission and reflection of vibration energy in the medium to high frequency ranges are investigated. The calculated power transmission and reflection coefficients are applied to the PFA method for the prediction of energy density and intensity in structures.
