Abstract

The invention discloses an aerodynamic force test device of a flapping wing flying robot, belonging to the technical field of stress-strain tests. The device comprises a fixing frame, a horizontal force sensor, a vertical force sensor, a test platform skeleton, a drive motor, a flapping device and a wing width adjusting plate, wherein the brackets with the horizontal force sensor and the vertical force sensor are mounted on the fixing bracket respectively; the test platform skeleton is connected with the connection brackets on the horizontal and vertical force sensors through a first flexible hinge and a second flexible hinge respectively; a counter weight is mounted at the test platform skeleton end close to the vertical force sensor; the flapping device connected with the drive motor is mounted on the test platform skeleton between the horizontal and vertical force sensors; a diffuse reflection switch is mounted on the bracket with the vertical force sensor at a position close to the flapping device; and the horizontal and vertical force sensors, the diffuse reflection switch and the motor are connected with an electric control part respectively. According to the invention, the force test precision is improved, and the interference of the force not in the force test direction on the force sensors is reduced.

Description

technical field [0001] The invention belongs to the technical field of stress and strain testing, in particular to an aerodynamic testing device for a flapping-wing flying robot. Background technique [0002] In recent years, with the rapid development of MEMS technology, micro air vehicle has become a new research direction. Micro flapping wing aircraft has received more attention because it is easier to overcome the problems of aerodynamic efficiency and flight control at low Reynolds number, and has a broader development prospect. [0003] The California Institute of Technology (Caltech) was one of the first institutions to develop a flapping-wing flying robot. It jointly developed Microbat with the University of California (UCLA) and AeroVironment. The first prototype was tested in October 1998. It is the earliest bionic flapping wing flying robot. Microbat's body skeleton and wings are made of new super-strong composite materials. The wings imitate the wings of bats a...
