摘要
为了满足港口环境监测、海洋资源调查的要求,设计研发了一款装配T型水翼的电动双体水翼船,同时为了优化翼形和结构,对水翼进行了形状优化和轻量化设计。首先,将Fluent软件计算得到的水动力载荷施加到T型水翼表面,结合ANSYS Workbench软件提出了形状-拓扑的分级优化方法,通过形状优化确定了T型水翼的展弦比、尖削比和攻角等关键参数。其次,对初始结构进行有限元分析后发现其符合设计要求,并有很大优化空间,进而通过拓扑优化,确定了水翼立柱采用薄蒙皮和柱状翼梁结合的结构,水平主翼采用薄蒙皮、“双工”字型翼梁和多翼肋结合的结构。最后,优化后的T型水翼结构符合设计要求,质量减少了34%。
In order to meet the requirements of port environmental monitoring and marine resource investigation,an electric twin-body hydrofoil equipped with a T-shaped hydrofoil is designed and developed.At the same time,in order to optimize the shape and structure of the hydrofoil,the shape and lightweight design of the hydrofoil is optimized.First,the hydrodynamic load calculated by the Fluent software is applied to the surface of the T-shaped hydrofoil,and combined with the ANSYS Workbench software,a shape-topology hierarchical optimization method is proposed.Through shape optimization,key parameters such as the aspect ratio,tipping ratio and angle of attack of the T-shaped hydrofoil are determined.Second,after finite element analysis of the initial structure,it is found that it meets the design requirements and has a lot of room for optimization.Furthermore,through topology optimization,it is determined that the hydrofoil column adopts a combination of thin skin and column spar,and the horizontal main wing adopts a structure of thin skin,"double I-shaped"spar and multi-rib.Finally,the optimized T-shaped hydrofoil structure meets the design requirements and the mass is reduced by 34%.
