摘　　要：以潜艇操纵面的几何尺度和纵向位置为设计变量,估算归一化后的无因次水动力系数,建立潜艇操纵性指标预报数学模型。基于iSIGHT优化平台,采取NCGA遗传算法开展潜艇操纵性指标的多目标优化设计,给出改进的优选方案,并进行灵敏度分析,评估操纵面参数对操纵性指标的影响。The dimensions and the longitudinal coordinates of the control surfaces are selected as the design variables,the unitary dimensional hydrodynamic coefficients are calculated and the submarine maneuverability prediction model is established.Based on the iSIGHT optimization platform,the Multi-objective optimization and Sensitivity analysis of the submarine maneuverability objects are carried out,the optimized results are given and the influence to the maneuverability by the control surfaces＇ parameters is evaluated.
