摘　　要：运输类船舶货载量较大,需要提升船舶稳定性与航行效率,因此设计了基于仿生理论的船舶外部造型设计优化方法。以鲸鱼鳍作为仿生对象,利用CATIA三维建模软件构建仿生鲸鱼鳍的几何模型,以该模型为基础计算仿生鱼鳍的运动学特性,以此模拟出应用在船舶的运动特性,确定该特性后,使用扩散光顺方法和局部网格重构方法实现仿生鲸鱼鳍模型的网格划分,将该仿生鲸鱼鳍应用于船舶实现船舶外部造型设计优化。试验结果显示,经过优化后的船舶外部造型兴波阻力与综合阻力更小,航行速度更快,即使在高载货量下依旧具有较为理想的稳定性,船舶外部造型设计优化效果较好。Transport ships have large cargo loads and need to improve ship stability and sailing efficiency.Therefore,this paper studies the optimization of ship external modeling design based on bionic theory.With whale fin as the bionic ob-ject,CATIA 3D modeling software was used to build a geometric model of the bionic whale fin.Based on the model,the kinematics characteristics of the bionic whale fin were calculated to simulate the motion characteristics applied in ships.After determining the characteristics,the meshing of the bionic whale fin model was realized by using diffusion fairing meth-od and local mesh reconstruction method.The bionic whale fin is applied to the ship to achieve the optimization of the ship exterior design.The test results show that the optimized propagation external shape wave resistance and comprehensive res-istance are smaller,the sailing speed is faster,and the ship external shape design has ideal stability even under high cargo load,and the optimization effect is better.
