A testing device for a current-carrying friction and wear performance of a flexible rolling friction pair, including a base plate, supporting profiles, and guiding rail sliders, and a screw assembly, and a movable supporting plate, and a fixed supporting plate, and first bearing supports, and a slider supporting plate, during the testing process, friction moment and friction force of the flexible rolling electrical contact component can be obtained by monitoring dynamic torque of rotating wheel, which is wide applicability, which allows simultaneous online monitoring of multiple experimental variables such as friction performance, current-carrying capacity, preload, friction force, and temperature; and at the same time, there is no need to adjust, assemble, or test multiple objects for the rolling ring structure; the testing process can be completed by only adjusting and testing the key electrical contact test piece, significantly simplifying the testing structure and method while reducing testing costs.
