摘要
对于管束振动引起的辐射声场的分析,利用解析法较为困难．运用有限元分析法对管道耦合振动噪声进行了比较系统的分析,得到一系列有益结果,为振动噪声控制提供了理论依据．
It is difficult to use a theoretical method to analyse the radiated sound field caused by the vibration of pipes. In this paper, an analysis of the radiated sound field caused by the vibration of pipes is made using the finite element method. The pattern of the pressure distribution of the sound field was obtained from the calculation, which provides a basis for vibration noise control.
