摘　　要：以海洋内波流场和密度场数值模拟结果作为外部驱动数据,提出基于数据驱动的潜体受内波影响的仿真分析方法,利用六自由度运动方程计算了潜体以不同潜深和初始速度通过模拟内波区时的运动响应,并根据运动响应的定量分析结果和非线性内波特点,给出了潜体水下航行安全及操纵的初步建议,该研究对于潜体水下航行安全具有重要应用价值。Taking the numerical simulation results of ocean-internal-waves fluidity and density field as the external driving data on the submerged body,a simulation analysis method based on data driving for the influence of internal wave on the submerged body is proposed.The motion response of a submerged body passing through the simulated internal wave zone is calculated by using the six degree of freedom motion equation.According to the quantitative analysis results of the motion response and the characteristics of nonlinear internal waves,the preliminary suggestions for the safety and control of the underwater navigation of the submerged body are put forward.This research has an important application value for the safety of underwater navigation.
