Method for reliably predicting service life of conductive slip ring

The invention relates to the technical field of conductive slip rings, in particular to a method for reliably predicting the service life of a conductive slip ring. The method comprises the following steps: setting the initial rotating speed of conductive slip ring rotating disc experiment equipment, and rotating the conductive slip ring; increasing the rotating speed of the conductive slip ring, and carrying out contact resistance and wear morphology detection on the conductive slip ring after the conductive slip ring runs at the high rotating speed for a period of time; if the friction form of the conductive slip ring is changed, detecting the rotating speed of the conductive slip ring obtained when the friction form of the conductive slip ring is changed as an acceleration stress parameter, and performing range grouping on the parameter to divide the parameter into multiple groups of continuous acceleration stress ranges; respectively taking a plurality of different rotating speeds according to a certain t
