A three-degree-of-freedom flapping motion test platform

Abstract

The invention discloses a three-degree-of-freedom flapping wing motion test experimental platform. Integrated transfer type differential gear train design is adopted, at the bottom, a differential gear train is driven by a pair of motors to achieve two-degree-of-freedom motion of a flapping wing, the top is driven by another motor, a bottom experimental device is driven to conduct integrated transfer motion, and three-degree-of-freedom motion is achieved. A six-axis force sensor is integrated between the wing and a motion shaft and connected with the experimental platform through a coupler. The experimental platform is high in degree of freedom and can simulate a more comprehensive motion form of an insect flapping wing; adaptability is wide, and various flapping wings can be tested only through replacement of a flapping wing structure; and meanwhile, the six-axis force sensor is connected with the flapping wing, so that measurement accuracy is improved.

Description

technical field [0001] The invention relates to a three-degree-of-freedom flapping wing test experiment platform, which is a flapping wing experiment platform which is especially aimed at insect-proof movement and can realize three-angle movements. Background technique [0002] The aerodynamic test system of the micro-orthopting-wing aircraft is a test platform designed by the Shenyang Institute of Automation to test the lift and thrust of the micro-orthoping-wing aircraft. The schematic diagram of the platform is as follows figure 1 As shown in the figure, it is simply marked, Fx is the horizontal force, representing thrust, Fy is the vertical force, representing lift, F is the resultant force of the two, G represents gravity, and the movement is measured through the two force sensors at the top and the tail The lift and thrust of the flapping-wing aircraft under the condition are simple in structure and high in sensitivity. [0003] However, this test platform has many l...

Problems solved by technology

[0003] However, this test platform has many limitations. First, it can only test the aerodynamic state of the complete flapping wing aircraft, and cannot perform aerodynamic tests specifically for the flapping wing; secondly, it can only measure lift and thrust in two directions. force, it is impossible to measure the force of more angles and more motion states; finally, the platform has a single degree of freedom in the flapping motion and less degrees of freedom, so it is not suitable for complex insect flapping motion research
