摘　　要：从水动力学理论的角度分析,鱼类巡游状态下鱼体推力与水阻力组成平衡力系。为获得水动力性能优良的仿生鱼鱼体外形,论文以回转体线形为基础,实现多种鱼体模型的参数化构建并进行阻力分析计算,据此设计阻力性能优良的鱼体线形。结合理论分析与生物学研究,完成尾鳍参数设计并对其进行水动力分析以确定最优组合。利用经验公式对仿生鱼整体阻力进行估算并进行仿真验证,结果证实所设计仿生鱼外形拥有优良的阻力性能。From the perspective of hydrodynamic theory,the fish body thrust and water resistance form a balanced force sys⁃tem in the fish cruising state.In order to obtain a bionic fish body shape with excellent hydrodynamic performance,this paper takes the rotary body line shape as the basis,realises the parametric construction of various fish body models and carries out the calcula⁃tion of resistance analysis,and then designs a fish body line shape with excellent resistance performance accordingly.Combining theoretical analysis and biological research,the design of caudal fin parameters is completed and hydrodynamic analysis is carried out to determine the optimal combination.The overall drag force of the bionic fish is estimated using empirical formulae and verified by simulation,and the results confirm that the designed bionic fish shape has excellent drag performance.
