摘　　要：船舶在航行过程中,船舶结构会受到各类复杂机械设备激励载荷作用,由于船用机械设备种类繁多,且运行方式各不相同,使得设备对于船舶结构的激励方式也不相同,根据设备振动机理,部分设备在运行过程中会产生不平衡激扰力或者不平衡激扰力矩。针对典型设备激励载荷作用下船舶结构振动声辐射问题,本文以船舶舱段结构基准模型为例,使用声固耦合法,从"设备-基座-船舶结构"系统耦合振动角度出发,以船舶结构辐射噪声为考核量,探究了舱段结构在设备不平衡激扰力、不平衡激扰力矩、不平衡激扰力与力矩联合作用等典型设备激励载荷作用下辐射噪声的影响变化。During the voyage of the ship, the hull structure will be subjected to various types of complex mechanical equipment excitation loads. Due to the variety of marine mechanical equipment and the different modes of operation, the equipment has different excitation methods for the ship structure. According to the vibration mechanism of the equipment,Some equipment will produce unbalanced disturbance force or unbalanced disturbance torque during operation. Aiming at the problem of vibration and acoustic radiation of ship structure under the excitation load of typical equipment, this article takes the ship cabin structure reference model as an example, uses the acoustic-solid coupling method, from the perspective of coupling vibration of the equipment-base-hull structure system, and takes the hull structure Radiation noise is the assessment quantity, and the influence of the radiation noise of the cabin structure under the typical equipment excitation load such as equipment unbalanced disturbance force, unbalanced disturbance torque, unbalanced disturbance force and moment combined action is explored.
