船用基座的减振降噪特性分析

Analysis on Vibration and Noise Reduction Characteristics of Pedestal of Marine Bases

船用基座是机械设备与船体连接的重要构件,对于振动和噪声具有双向传导的功能,设计基座时不仅需要考虑其支撑作用及结构强度,也要考虑基座对于振动传递的控制功能。本文从结构强度以及减振降噪两方面比较常见的结构钢基座和复合材料基座,针对复合材料基座的特性,对其进行强度分析和减振降噪分析并进行总结。

Marine base is an important component of the connection between mechanical equipment and hull, for vibration and noise has the function of two-way conduction, the design of the base not only needs to consider its support and structural strength, but also consider the base for vibration transmission control function. In this paper, the structural strength and vibration and noise reduction of structural steel base and composite material base are relatively common. In view of the characteristics of composite material base, the structural strength analysis and vibration and noise reduction analysis are carried out, and summarized.
