摘　　要：该文介绍振动噪声分析的内容,并以某海洋平台为例,对平台主机基座结构进行模态分析和平台舱室噪声分析。分析结果表明,主机基座结构的固有频率完全超出主机的频率范围,主机基础能够避免与主机发生共振,且平台舱室噪声均能够满足规范要求。此外文中还给出减振降噪设计方案。This paper introduces the content of vibration and noise analysis,and takes an offshore platform as an example to carry out modal analysis and platform cabin noise analysis of the main engine base structure of the platform.The analysis results show that the natural frequency of the mainframe base structure is completely beyond the frequency range of the mainframe,the mainframe foundation can avoid resonance with the mainframe,and the noise of the platform cabin can meet the requirements of the specification.The design scheme of vibration and noise reduction is also given in this foreign language.
