The invention discloses an unmanned aerial vehicle propeller balance rapid testing device and an unmanned aerial vehicle propeller balance rapid testing method. The unmanned aerial vehicle propeller balance rapid testing device comprises a bottom plate; a magnetic suspension support and a propeller balance controller, which are disposed on the bottom plate; and a testing component. The magnetic suspension support is detachably connected with the testing component. The testing component is used to carry a to-be-tested unmanned aerial vehicle propeller, and the magnetic suspension support is used to carry the testing component. The propeller balance controller is used to acquire the rotation direction and the speed of the to-be-tested unmanned aerial vehicle propeller, and is used to determine the gravity center offset direction thereof according to the acquired rotation direction and the acquired speed. The testing component comprises a magnetic suspension shaft, a propeller fixing button, a grating disc, and a grating sensor. Based on the unmanned aerial vehicle propeller balance rapid testing method of the above mentioned device and the grating sensing technology, the grating disc is used to acquire the rotation direction and the acceleration direction of the to-be-tested propeller, which are converted into pulse signals by the grating sensor, and then the gravity center offset direction of the propeller is acquired quickly, automatically, and accurately by the phase differences and the pulse widths of the pulse signals.
Description
technical field [0001] The invention belongs to the technical field of multi-rotor UAV testing, and more specifically, relates to a fast testing device and method for UAV propeller balance. Background technique [0002] At present, the method of adjusting the balance of the center of gravity of the multi-rotor UAV propeller is mostly manual adjustment with the help of the magnetic suspension balance shaft. First, fix the propeller to be adjusted on the magnetic suspension balance shaft, and then place the magnetic suspension balance shaft on the special bracket. If the center of gravity of the propeller is not on the same line as the axis of the magnetic levitation balance shaft, the propeller to be adjusted will deflect slowly under the action of gravity. The center of gravity of the propeller is adjusted by grinding the material of the propeller in the direction of the propeller; after grinding, measure the offset direction of the center of gravity in the same way again, a...
