| 摘 要： | 对水下滑翔器主体外形的优化设计问题进行研究.首先,在考虑内部机械结构限制的条件下,建立了主体外形优化数学模型,并采用CFX计算了若干主体形状的绕流阻力.在此基础上建立了映射主体外形的尺寸参数与绕流阻力的BP神经网络.然后将建立的神经网络作为优化设计问题的目标函数,采用坐标轮换法对滑翔器主体外形进行了优化设计,确定了尺寸参数的最优解.

| Abstract: | Optimization of hull shape of autonomous underwater glider is studied.Taking into account the limit to interior mechanism,the mathematical model for optimizing hull shape is built.Drag forces of water flow around some different hull shapes are computed by CFX.On basis of results of computing,a BP neural network is designed to compute dimension and drag force of hull shape,which is then used as object function for optimization.The optimization of hull shape is gotten using coordinate alternation method. |
