摘要：
The sound radiation impedance matrix of a rectangular plate facing shallow water was derived analytically. By the eigen-value decomposition technique, the sound radiation modes and their radiation efficiencies were obtained and used to study the sound radiation characteristics of the plate in shallow water. The effect of water depth on the sound radiation and modal added mass was discussed. The results show that underwater natural frequencies of the plate are related to the distribution of added mass while the variation of radiation efficiencies of radiation modes in different depth of water will influence the sound radiation. © 2020, Editorial Office of Journal of Vibration and Shock.
