Internal solitary waves (ISWs) pose a significant threat to underwater submersibles. Unlike low-speed submersibles in the ISW field, high-speed form large pitching angle, which is more dangerous for submersible maneuverability. However, mechanisms behind interaction between ISWs and still remain unexplored. In this work, three-dimensional numerical model ISW–structure used investigate motion response characteristics of field. Based on extended Korteweg–de Vries (eKdV) theory, generated two-layer tank by enforcing velocity inlet boundaries. The evolution obtained solving Navier–Stokes equations. self-propelled simulated equation submersible. Using model, investigation performed. effects depth, self-recovery stiffness, amplitude are analyzed systematically. When initial position above trough depth close may pierce through surface, further results formation stall “falling deep.” It difficult with low recovery stiffness maintain or control navigation trajectory. They would undergo angle even impact seabed.
