摘要：
For solving the problem of a large number of geometric deformation parameters and a large consumption of computational resources in hull shape optimization, a self-blending method capable of realizing the 3D hull surface deformation with few parameters was proposed. Besides, the hull shape optimization of a high-speed ship was studied by combining CFD method and multi-island genetic algorithm. Six blending factors combined with the basic cross section extracted from original ship were used to blend and produce new cross sections, from which the 3D hull surface was reconstructed. The objective function (total hull drag coefficient) was numerically predicted by CFD method, and the uncertainty of the numerical calculation method was verified. The response surface was used as a surrogate model to reduce the number of computing cycles by more than 90% and the consumption of computing resources was greatly reduced. The total drag coefficient of the target ship was decreased by 9.76%, verifying the effectiveness of the method in hull shape optimization. © 2022, Editorial Board of Journal of Ship Mechanics.
