基于确定性及稳健性优化的水下航行器外形减阻研究
Research on drag reduction of underwater vehicle shape based on deterministic and robust optimization
摘要
Abstract
[Objective]This study aims to improve the endurance and performance stability of autonomous underwater vehicles.[Method]Three common axisymmetric bodies were selected as candidates for the AUV's main body shape.Three CFD models were developed to calculate their volumes and hydrodynamic re-sistance.The Myring profile was selected as the preferred main body shape of the AUV.The range of parame-ters for the Myring profile equation was then defined.The Latin hypercube experimental design method was used to generate design variable samples and corresponding response values.Based on the sample points,an approximate model was constructed.After the approximate model was established,analyses of fitting accura-cy,sensitivity,and response surface were performed.Once the approximate model achieved the required fit-ting accuracy,a multi-objective optimization model was established for deterministic optimization,and the op-timal solution was obtained.Reliability analysis of the optimal solution was then conducted on the optimal so-lution,followed by robust optimization to enhance its reliability.[Results]The results show that after deter-ministic optimization,the resistance decreased by 5.96%and the volume decreased by 0.78%compared to the initial values.Compared to the deterministic optimization result,robust optimization increased resistance by 0.35%and volume by 0.14%,while achieving a reliability level of 6σ.[Conclusion]Both deterministic and robust optimizations reduce the resistance of underwater vehicles,with robust optimization further enhancing the stability of design variables.关键词
