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.
