The underwater vehicle exiting from wave is an unsteady and non- linear moving process. It contains passing through the different material faces and the dramatically changed motion parameters. The fluid dynamics and dramatic loading change can impact the gesture of underwater vehicle exiting from wave and moving in the air. Direct at these problem,this paper made use of boundary condition to simulate the Stokes wave theory firstly. On this foundation,based on the RANS equation,we made use of dynamic mesh technique to simulate the gesture of underwater vehicle exiting from wave,analyzed the influence by the changed of the phase position of wave particularly,and obtained the phase position of wave that influence the gesture of underwater vehicle most seriously on the same wave parameter. The research conclusion can make reference to the parameter design for the trajectory of underwater vehicle.
