    Abstract
  • Multi-objective optimization of underwater glider with blended-wing-body(BWB) is carried out in terms of the mass and deformation of structure by employing the non-dominated sorting genetic algorithm(NSGA-II).The Maximum equivalent stress and bulking factor are taken as the constraint conditions. Parametric modeling of the BWB underwater glider structure is implemented using UG secondary development and finite element analysis is performed to obtain the structural performance of the underwater glider via the commercial computational structural mechanics software ANSYS. Finally, the Pareto optimal solution set of this multi-objective optimization problem is obtained by several iterations, and the technique for ordering preferences by similarity to ideal solution(TOPSIS) is used to obtain some trade-off optimum design points from Pareto fronts. This optimization process may provide a reference for structure optimization design of BWB underwater glider
