改装FPSO模块化生活楼振动与舱室噪声研究

Research on modification of FPSO modular living building vibration and cabin noise

文章以某改装FPSO模块化设计生活楼为研究对象,采用有限元法建立生活楼结构振动分析模型,对其总振动进行计算。并基于统计能量法,建立生活楼舱室噪声分析模型,计算舱室噪声,结果表明,生活楼舱室噪声满足IMO A 468(XII)舱室噪声限值要求,居住和办公场所噪声性能优于母型船。

The article takes a modified FPSO modular design living building as the research object, and uses the finite element method to establish the vibration analysis model of the liv!ng building structure, and calculates its total vibration. Based on the statistical energy method, a noise analysis model for living room cabins was established and the cabin noise was calculated. The results showed that the noise of cabins in living quarters meets the cabin noise limit requirements of IMO A 468 （XII） , and the noise performance of residential and office buildings is superior to that of parent ship.
