摘要
以海洋平台上动设备产生的大量振动噪声为研究对象,介绍了海洋平台等结构物声振耦合分析的数值方法以及噪声分析的相关软件。确定海洋平台上的噪声传播有空气声传播和结构声传播两种传播路径,计算分析时均须考虑。同时以某在建项目为例,预测了上层甲板动设备产生的噪声对生活楼房间的影响,并得出相应结论。
This paper focused on the noise emitted by the mechanical equipments, and mainly discussed the vibro-acoustic analysis methods and related software for offshore platforms and other similar structures. There are two paths during transmission： airborne transmission and structural borne transmission, both of them should be considered in analysis. Moreover, taking a current construction project as a sample, the influence of noise emitted from mechanical equipments at upper deck on the living quarter is predicted.
