Aiming at the process of underwater vehicle crossing the water-air interface based on the computational fluid dynamics(CFD)method,integrating the volume of fluid(VOF)and dynamic fluid body interaction(DFBI)models,a numerical simulation method for the trans-media process in a wave environment was studied.The motion simulation method of underwater vehicle under the action of complex fluid environment was established.The simula-tion of the water-exit process of the underwater vehicle in a wave environment has been realized.The accuracy veri-fication of the wave-making and trans-media processes has been completed.The hydrodynamic and kinematic char-acteristics of the vehicle during the water-exit process have been obtained.The influences of the wave phase and ve-locity on the force and motion characteristics of the underwater vehicle were obtained,which provides technical sup-port for designing the unmanned vehicles.
