摘　　要：以开发适用于小型潜器的仿生操纵与推进系统为研究背景,利用计算流体动力学软件Fluent对三维全鱼模型进行了数值模拟,建立了仿鱼形水下航行器的数值计算模型,研究了柔性变形系数下三维全鱼模型的推进性能以及流场结构结构特点,结果表明随着柔性系数的增加,阻力系数的幅值增大,从而为开发新型、高效的仿生推进系统提供设计依据和技术支撑。Aiming at the development of bionic maneuverable propulsion system applied in the small under-water vehiele. a three dimensional integral whole fish model is established by using 3D modeling software Prn/E, numerical simulation of hydrodynamic characler is completed by means of the computational fluid dynamic software FLUENT, The flow fieht structure and hydrodynamic perfnrmanee are calculated in different deformation modes. The effect of deformalion modes on the propulsion performance is studied. The result shows that integral whole fish model can obtain better performance under the undulatory deformation mode.
