The invention discloses a method for drag reduction by arranging microstructures on the surface of an underwater vehicle, which comprises the following steps of: drawing an underwater vehicle model by adopting three-dimensional drawing software, uniformly arranging groove-shaped drag reduction microstructures on the surface of the underwater vehicle, and arranging the drag reduction microstructures along the flow direction, simulation analysis software Ansys is used for conducting simulation analysis on the underwater vehicle model with the smooth surface and the surface provided with the different structures and the different number of sets of drag reduction microstructures, a surface friction resistance value is obtained, the drag reduction rates of the surfaces of the underwater vehicles with the different structures and the different number of sets of drag reduction microstructures are calculated according to the surface friction resistance value, and the drag reduction rates of the surfaces of the underwater vehicles with the different structures and the different number of sets of drag reduction microstructures are calculated according to the drag reduction rates. And designing the surface structure of the underwater vehicle in practical application by using the drag reduction microstructure corresponding to the maximum drag reduction rate. By means of the method, the running resistance of the surface of the underwater vehicle can be effectively reduced, the energy consumption of the underwater vehicle is reduced to the maximum degree, and energy is saved.
