Optimal Design and Drag Analysis for a Type of 6000 m Detective AUV
Pages: 47-51
Year: Issue:  1
Journal: Ocean Technology

Keyword:  ISIGHT优化阻力分析CFD仿真ANSYS CFX;
Abstract: 使用ISIGHT集成EXCEL,ICEM,ANSYS FLUENT软件,搭建封闭耦合优化仿真平台.根据任务需求和布置需要得到设计变量、状态变量和目标函数,采用多岛遗传算法,优化求解得到局部最优AUV设计结果.借助SOLIDWORKS设计得到全附体模型,使用ANSYS CFX分别在0°,±2°,±4°,±8°,±16°攻角的条件下,计算其阻力值,经过经验公式对摩擦阻力的计算结果进行理论验证,证明了计算结果的可靠性.为6000m级探测型AUV的总体方案设计提供了线型参考和布局依据.
