摘要

摘要: 无人水下航行器(UUV)在无人平台动态布放时易受平台航行的干扰, 因此对水下无人平台动态布放UUV过程水动力特性研究极为重要。文中基于雷诺平均法和湍流模型, 使用重叠网格并结合多参考系模型, 建立了一种适用于研究动态布放与双体分离的数值水池。通过开展典型算例研究, 将仿真结果与标模试验结果进行对比, 结果表明: 该方法仿真误差小于8%, 精度满足工程应用需求。进一步使用该方法对大型水下无人航行平台动态布放UUV进行仿真, 对该状态下UUV水动力参数进行预报, 并与自由航行状态参数进行对比, 结果表明: 布放状态下, UUV操作性较自由状态明显减弱, 对布放过程与控制策略设计具有一定的指导意义。

Abstract: Unmanned undersea vehicles(UUVs) can be easily interrupted by platform navigation during the dynamic deployment of unmanned platforms. Thus, it is important to study the hydrodynamic characteristics of UUVs during this process.?Based on a solution of Reynolds-averaged Navier-Stokes equations with the turbulence model, a numerical pool suitable for the study of the dynamic distribution and separation of multi-reference frame was established using overlapping grids and a multi reference frame model. A typical example study was compared with simulation results, and a model test was carried out. The results showed that the simulation error of this method was less than 8%, and the accuracy met the requirements of engineering applications. Finally, this method was used to simulate the dynamically deployed UUV from a large, unmanned platform, predict the hydrodynamic parameters of the UUV at this state, and make a comparative study with the parameters of a free navigation state. The results showed that the operability of the UUV in the deployment state was significantly less than that in the free state. The results of this study aid in the deployment process and control strategy designs.
