浮动地板在某居住舱室的应用研究

Research on the Application of Floating Floor in a Cabin

针对采用调整结构形式和敷设阻尼涂料2种措施降低船舶某居住舱室的振动与噪声收效甚微的问题,尝试采用船用浮动地板进行减振降噪,浮动地板原理、浮动地板构成、浮动地板施工工艺、测试方案和测试结果等5个方面进行阐述,验证船用浮动地板的减振降噪效果。运用浮动地板后,经过专用仪器测量,振动和噪声情况得到极大改善,对其他舱室的减振降噪有一定的指导和借鉴作用。

In view of the fact that structural form adjustment and application of damping coatings can barely solve the vibration and noise issues in aship cabin, this study tries to lower the vibration and noise by means of marine floating floor. The five aspects including the principles, composition, work process, testing plan and test results of the floating floor are elaborated and analyzed in this paper, and the effect of the floor in terms of vibration and noise reduction is checked. After the the float floor is installed, the vibration and noise condition are significantly improved according to the measurements by special instrument, which can provide some guidance and reference for the vibration and noise reduction in other cabins.
