水下监测设备翼型导流罩三维流固耦合研究

Three-Dimensional Fluid Structure Interaction of the Underwater Monitoring Equipment with Airfoil Section Fairing

为使水下监测设备在海洋环境中保持稳定正常工作,需要为其加装翼型导流罩,而在设计中,导流罩稳定效果评价成为重点。选取三维流固耦合方法,分别对水下监测设备和带导流罩水下监测设备进行仿真,得到振动位移响应。对比结果表明,加装导流罩后可使振幅减小、频率降低,证明了导流罩对水下监测设备确有稳定作用。

In order to make the underwater monitoring equipment work stably and effectively in the ocean environment,it is necessary to install an airfoil section fairing for the monitoring equipment.In the design,the evaluation of the stability effect of the fairing becomes important.Three-dimensional fluid structure interaction method is selected to simulate the underwater monitoring equipment and the equipment with fairing respectively,and the vibration displacement response is obtained.The comparison results show that the amplitude and frequency can be reduced after installing the fairing,which proves that the fairing has a stable effect on the underwater monitoring equipment.
