The invention discloses an underwater vehicle appendage design method. The method comprises the following steps: determining an initial value of a design variable according to an empirical formula; parameterized geometric modeling is carried out on wings and empennages of the underwater glider; performing initial sample point collection on design variables by applying an optimized Latin hypercube test design method; cFD simulation is carried out on the initial sample points, and initial sample point response values are obtained through calculation; constructing an approximate model by using a radial basis neural function; a genetic algorithm and a simulated annealing algorithm are selected to carry out collaborative optimization design on wings and empennages of the underwater glider, and global exploration is carried out on an approximate model; and performing CFD simulation on the obtained optimal geometric parameters of the underwater glider appendage. According to the method, the appearance of the underwater glider appendage is preliminarily calculated, so that the blindness and uncertainty of sample collection are greatly reduced; the coupling relation between the wing and the empennage is considered, and the situation that only a local optimal solution is found in the optimization process is avoided.
