摘　　要：为了提高水下无人航行器工作的可靠性和稳健性,本文采用多学科设计优化方法开展航行器的总体设计优化。首先开展水下航行器在总体设计阶段的学科设计,分析了各学科内部的模型和计算方法,明确了各学科输入、输出和耦合关系;开展了学科内参数建模,确立了总体设计的设计变量、系统参数和约束条件。然后以航行器质量最轻和机动性能最强为优化目标,获得设计变量计算最优解和优化设计主要输出结果值。设计变量优化计算值有效提高设计方案满足约束的能力,优化设计主要输出结果为水下无人航行器设计方案的选择提供了定量依据。To improve the reliability and robustness of the underwater unmanned vehicle,the multidisciplinary design optimization method is adopted to optimize the overall design of the vehicle.First,we conduct the discipline design of the underwater vehicle in the overall design stage,analyze the internal models and calculation methods of each discipline,and clarify the input,output,and coupling relationships for each discipline.We then perform parameter modeling within the discipline and establish the design variables of the overall design,system parameters,and constraints.By taking the lightest weight and strongest maneuverability of the aircraft as the optimization goals,we obtain the optimal solution for the design variables and the main output value of the optimal design.The optimized calculated value of the design variables effectively improves the ability of the design plan to meet the constraints.Moreover,the main output results of the optimized design provide a quantitative basis for selecting aircraft plans.
