Maneuverability, which is closely related to navigation safety, is an important part of the overall performance of an underwater vehicle. The purpose of this study is to analyze the dynamic response of an underwater vehicle to internal waves at different angles and speeds. A combination of experiments and numerical simulations is used to compare the forces on the underwater vehicle. In terms of fluidstructure coupling, the internal wave interface is tracked by the VOF method. In this paper, waves of the same amplitude ratio as the numerical results are simulated using a wave-making sphere. The validity of the numerical method is verified by comparing with the rotation moment test of the underwater vehicle. The results show that different angles of attack have significant effects on the forces and moments of the underwater vehicle and that choosing the right angle of attack and rotation speed can limit the dangerous depth. The conclusion is of certain significance for the safety of underwater navigation.
