Abstract
Describe are an OPGW single wire torsional fatigue test method, apparatus and storage medium. The method includes: a preset torsional angle and preset cycle number of torsions of an OPGW single wire are acquired (S); forward and backward torsional forces are sequentially and alternately applied to the OPGW single wire according to the preset torsional angle (S); when a number of application times of the applied torsional forces reaches a preset cycle number of torsions, torsional force application to the OPGW single wire is stopped (S). According to the test method, a bidirectional torsional fatigue test on the OPGW single wire may be made by sequentially and alternately applying the forward and backward torsional forces to the OPGW single wire, so that reliability of a test result and test efficiency are improved. In addition, a torsional force loading device is controlled by a control device of the test apparatus in the disclosure to make the bidirectional torsional fatigue test on the OPGW single wire, meanwhile, a unidirectional torsion test and a tensile test may further be made on it, and the apparatus is easy to operate and diversified in function.
