摘　　要：UUV与水下对接装置对接的过程中存在双体干扰问题,非线性特征强烈。为了探明UUV在对接过程中流体动力随着对接姿态以及运动距离变化规律,本文借助Fluent软件中的动网格技术开展非定常工况下UUV动态回收过程的数值模拟研究。系统分析UUV运动速度、运动姿态(主要是攻角)对其流体动力性能以及流场结构的影响。本文研究成果可为后续样机试验提供技术指导和理论支撑。In the process of docking between UUV and underwater device,there exists a problem of two-body interference with strong nonlinear characteristics.In order to find out the change of hydrodynamic force with docking attitude in the process of UUV docking,this paper adopts the dynamic grid technique to carry out the numerical simulation research on dynamic recovery process of UUV.The influence of UUV motion velocity and attitude on its fluid dynamics and flow structures is systematically analyzed.The research results of current paper can provide technical guidance and theoretical support for subsequent prototype tests.
