摘要

摘要: 具有中间鳍/对鳍(MPF)推进模式的仿生水下航行器, 因其优良的机动性、稳定性, 在海洋科考、海洋资源开发以及军事侦查领域具有明显的应用优势, 文中建立了MPF推进模式的典型代表——仿鳐鱼水下航行器外形轮廓和游动方程, 分析了仿生参数对其游动的影响, 并通过Fluent UDF编写游动方程, 实现仿鳐鱼水下航行器动态流体仿真。仿真结果表明: 仿鳐鱼鱼鳍波动形成旋向相反的尾涡并不断向后脱离, 提供向前推力, 为仿鳐鱼水下航行器设计提供技术参考。

Abstract: Bionic undersea vehicles with median and/or paired fin(MPF) propulsion modes have obvious application advantages in marine research, marine resource development, and military research owing to their excellent mobility and stability. The contour and motion equations of bionic ray undersea vehicles are established as a typical model of the MPF propulsion mode to analyze the influence of bionic parameters on the motion. The motion equation is written using Fluent UDF to realize dynamic fluid simulation of bionic rays, and the simulation results show that the bionic fin undulates to form a vortex that spins in opposite directions and constantly pulls back, providing forward thrust. This paper provides a technical reference for the design of bionic rays underwater vehicles.
