However, at present, there is a lack of special equipment capable of comprehensively testing the torque, tension and pressure, revolution speed, contact resistance and wear amount for the current-carrying friction and wear experiment of the conductive rolling ring. The existing experimental devices have single function, and only a few parameters can be tested each time, which not only is low in experimental efficiency, but also is poor in the synchronization of parameter testing, and thus the comprehensive performance of the conductive rolling ring under the actual working condition cannot be accurately reflected, greatly limiting the research and development process and performance optimization of the conductive rolling ring.
