摘　　要：为了降低船舶的振动噪声,本文研究了不同材料对于船舶减振降噪性能的影响,分别设计了低频和高频状态下的数值计算模型,对船体不同位置进行振动噪声分析和对不同材质船舶进行振动噪声分析,希望能为降低船舶噪声提供一些参考。In order to reduce the vibration and noise of the ship, this paper studies the influence of different materials on the vibration and noise reduction performance of the ship. The numerical calculation models under low frequency and high frequency are designed respectively. The vibration and noise analysis is carried out on different positions of the hull and the ships of different materials are carried out, hoping to provide some reference for reducing ship noise.

关 键 词：振动噪声 复合材料 数值计算 统计能量
