Bionic flapping wing propulsion test platform

Abstract

The invention discloses a bionic flapping wing propulsion test platform and belongs to the field of bionic tests. The bionic flapping wing propulsion test platform comprises two motion modules, two air floating guide rails and an air floating guide rail bracket; the air floating guide rail bracket is used for supporting the whole test platform, and the two air floating guide rails are fixed to twoends of the air floating guide rail bracket in parallel; the two ends of the motion module are respectively and slidably connected with the two air floating guide rails, so that horizontal translation and rotation of bionic flapping wings are achieved; the two motion modules are used for achieving the flapping wing motion of an imitation ray; each motion module comprises two stepping motors for controlling horizontal translation and rotation of the clamping the flapping wings, so that independent motion of single motion module and coordinated motion of multiple motion modules are achieved; the movement of the ray can be simulated more realistically, and the moving part is supported through the air floating guide rails, so that the free movement of the test platform in the propelling direction is achieved, and the precision of a whole propelling device is improved; and when the bionic flapping wing propulsion test platform is suitable for other bionic flapping wing propulsion experiments, the experimental effect can be achieved by directly increasing the number of the motion modules.

Description

technical field [0001] The invention belongs to the field of bionic tests, in particular to a bionic flapping wing propulsion test platform. Background technique [0002] Due to its advantages of high efficiency, good flexibility, and low noise, flapping wing propulsion has become a hot spot in marine science research recently. As an outstanding representative of flapping and propulsive fish, rays have received extensive attention in their form of motion. People use high-speed cameras to capture the motion of rays and establish a mathematical model of their motion. Based on the mathematical model, the researchers used various forms of motion mechanisms to simulate the motion form of the ray, so as to analyze the relevant characteristics during its motion. Due to the extremely complex motion of the actual ray, the existing experimental devices simplify its motion to a single axis of pitching motion, heave motion or a combination of the two, and fix the motion axis at a cert...
