摘　　要：为分析水下拖缆在一定流速下的振动响应,使用ANSYS Workbench平台并基于双向流固耦合计算方法构建三维水下拖缆涡激振动的数值仿真框架,并对1 kn均匀流速下的拖缆涡激振动响应进行数值模拟分析。仿真得到了拖曳力、升力,振幅以及位移轨迹变化结果,为进一步研究拖缆振动响应对水下探测系统的影响提供了一定研究基础。In order to analyze the vibration response of underwater towing cables in a certain velocity,a numerical simulation framework for calculating the vortex-induced vibration response of a three-dimensional underwater towing cable based on fluid structure coupling calculation is built on ANSYS Workbench.The numerical simulation analysis of the vortex-induced vibration response of the towing cables in 1 kn uniform flow velocity is carried out.The drag force,lift force,amplitude and displacement are obtained.It provides the technical bases for the further research on the influence of towing cable vibration response on underwater detection system.
