| 摘 要： | 以临近空间飞艇为对象，针对传统外形设计方法中存在的问题，提出了新的优化设计方法，搭建了流程框架，编制了优化程序。首先研究了遗传算法及多学科设计理论，进而在此基础上建立了飞艇阻力、体面比、应力模型，利用多学科设计理念对飞艇气动、结构、强度进行了一体化设计。其次将遗传算法引入到优化设计当中，并利用Matlab和Fluent开展了联合仿真研究。最后结合实际应用需求进行了算例分析，验证了该方法的可行性和效果。

| Abstract: | A new multidisciplinary design optimization(MDO) method based on genetic algorithm was developed.The theoretic framework was built and an optimization program was designed.Firstly,genetic algorithm and MDO method were studied,and the resistance model,volume-suface ratio model,stress model were built,and the MDO method integrating aerodynamics,structure,and strength was introduced.Secondly,the genetic algorithm was used to optimize the airship shape which concluded a composite objective function,and a co-sim... |
