Test apparatus used for unmanned aerial vehicle motor dynamic tension and torsion

Abstract

The invention relates to a test apparatus used for unmanned aerial vehicle motor dynamic tension and torsion. The test apparatus comprises a transition assembly, a tension test assembly and a torsion test assembly, wherein the transition assembly comprises a test shaft and a sleeve, and one end of the test shaft is mutually rotationally connected with a housing of a motor through the sleeve; the tension test assembly comprises a first tension meter, the first tension meter is connected with the other end of the test shaft, and the first tension meter detects an axial force of the test shaft; and the torsion test assembly comprises a second tension meter, a drag rope and a roller, and the drag rope, after being led out from the circumferential direction of the test shaft, is led to the second tension meter through the roller. According to the invention, tension generated by a rotor motor can be accurately measured in real time, and the motor torsion can also be simultaneously measured in real time; and through arrangement of the torsion test assembly, the drag rope is enabled to overcome the torsion to balance rotation forces of blades, the test shaft is enabled to maintain still, it is ensured that the first tension meter does not jitter when the tension is tested, and the test accuracy is improved.

Description

technical field [0001] The invention relates to a testing device for dynamic tension and torsion of an unmanned aerial vehicle motor. Background technique [0002] Plant protection drones serving agriculture have developed rapidly in developed countries such as Japan and the United States. According to the latest statistics from the Ministry of Agriculture, as of June 5, 2016, there were more than 300 companies producing professional drones in my country, of which more than 200 were plant protection drone manufacturers, producing a total of 178 plant protection drones. There are more than 5,000 of them in stock. The Chinese drone market is booming. [0003] The performance of plant protection UAVs is usually based on the load capacity and endurance as a constant standard. The load capacity is mainly reflected by the pull of the motor equipped with blades. The endurance is mainly based on the amount of power consumed in the load state. The torque value of the motor and the ...

Problems solved by technology

[0004] Most of the existing UAV motor test devices can only test the tensile force, but cannot test the torque at the same time; moreover, a tension meter with a large stroke is mostly used, the test system jitters seriously, and the accuracy of the test value is not enough
