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.
Key words: data drive; nonlinear internal waves; six degree of freedom
