摘　　要：为保证船舶能符合船级社及国际组织对船舶振动与噪声控制的要求,在设计阶段必须对船体进行振动与噪声分析和预报。以某大型船舶为研究对象,采用声固耦合法和附加质量法对其船体振动情况进行计算分析,采用统计能量分析(Statistical Energy Analysis,SEA)法对其舱室噪声进行计算分析。计算结果表明,该方法能较为准确地模拟船体振动与舱室噪声,满足工程预报的要求,对船体振动与舱室噪声预报相关的工作的开展具有较好的参考价值。To ensure that a ship meets the requirements on vibration and noise control issued by classification societies and international organizations,the analysis on hull vibration and noise must be carried out at the design stage.The acoustic structure coupling method and the additional mass method are used to calculate and analyze the vibration of a large ship,and the Statistical Energy Analysis(SEA)method is used to calculate and analyze the cabin noise.The results indicate that the methods can accurately simulate the vibration and cabin noise of ships,which has met the requirements of engineering prediction,and could be a good reference for engineering calculations regarding prediction of ship's vibration and cabin noise.
