Abstract

The invention discloses a hydrodynamic performance testing method for a biomimetic flexible flapping wing mechanism, and belongs to the field of biomimetic testing. The biomimetic flexible flapping wing adopts a naca airfoil profile, and the material of the biomimetic flexible flapping wing is silica gel. The hydrodynamic performance testing method for the biomimetic flexible flapping wing mechanism adopts a hydrodynamic performance testing device which comprises a biomimetic flexible flapping wing motion propelling platform, a biomimetic flexible flapping wing and a PIV (Particle Image Velocimetry) testing system. By use of the hydrodynamic performance testing method for the biomimetic flexible flapping wing mechanism, key parameters, including the energy conversion efficiency, the torquecoefficient, the thrust coefficient and the like, of the biomimetic flexible flapping wing for measuring the performance of the biomimetic flexible flapping wing can be tested, a reference can be provided for the design of a biomimetic flexible flapping wing engineering prototype, and an experiment basis can be provided for the CFD (Computational Fluid Dynamics) numerical simulation and the theoretical research of the hydrodynamic performance of the biomimetic flexible flapping wing.

Description

technical field [0001] The invention belongs to the field of bionic testing, in particular to a bionic flexible flapping wing mechanism and a hydrodynamic performance testing method. Background technique [0002] With the deepening of marine biology research, bionic flexible flapping wing propulsion has attracted widespread attention due to its high propulsion efficiency, good flexibility, and strong concealment. As an effective research method, experiment plays a crucial role in the study of hydrodynamic characteristics of flexible flapping wing propulsion. However, the existing hydrodynamic testing methods are mainly designed for the hydrodynamic characteristics of rigid bodies such as ships or underwater vehicles. Due to the large difference with experimental objects such as ships, the existing hydrodynamic testing methods cannot be directly transplanted into the hydrodynamic testing of bionic flexible flapping wings. The bionic flexible flapping wing mechanism and the ...
