Method and device for designing shell of underwater vehicle, and equipment

The invention relates to the technical field of underwater vehicles, and discloses a method and device for designing a shell of an underwater vehicle, and equipment. The method comprises the following steps: performing test design according to appearance parameter design variables of an underwater vehicle shell and a corresponding value range to obtain a plurality of groups of parameter test variable samples, and obtaining an optimization target sample corresponding to each group of parameter test variable samples according to the property of a determined optimization target; according to the parameter test variable sample and the corresponding optimization target sample, establishing a target approximation model of each optimization target about the shell appearance parameter design variable; and based on a genetic algorithm and the target approximation model, carrying out multi-target optimization of the underwater vehicle shell, obtaining an optimized shell appearance parameter value and an optimized targe
