拖曳线列阵隔振模块结构的建模及计算分析

Modeling and Calculation of Vibration Isolation Module in Towed Array Sonar

隔振模块是拖曳线列阵的重要组成部分,本文采用ANSYS有限元软件,建立了考虑护套内硅油和护套外水这两种流体的两层流固耦合模型,计算分析了隔振模块在水下的隔振性能,得到了一些重要的分析结果。这些计算数据和分析结果,为线列声纳阵水下拖缆隔振段的设计提供了技术依据。

The VIM(vibration isolation module) is one of the most important components in towed array sonar.The fluid-structure coupling field model by using ANSYS finite element software is constructed and calculated.Through the analysis of the vibration isolation capability of VIM in water,some important results are obtained.The results from calculation and analysis can provide a technologic basis in the design of VIM for the underwater cable in towed array sonar.
