Abstract
The present invention discloses a pin-on-disk type in-situ current-carrying friction testing system, and belongs to the technical field of friction performance testing. The friction testing system includes a pin-on-disk type friction pair, a current loading mechanism, and a magnetic field generating mechanism. The current loading mechanism includes a conductive terminal abutting against an annular sidewall of a disk specimen and used to guide a current in the disk specimen to flow along a horizontal direction, and the magnetic field generating mechanism is used to generate a magnetic field. When a pin specimen and a disk specimen rotate relatively, the pin specimen, the conductive terminal, and the magnetic field generating mechanism are relatively stationary, and an Ampere force generated by the current in the disk specimen flowing in the horizontal direction under the action of the magnetic field faces a support platform.
