Multi-working-condition friction-wear test simulation device suitable for revolute pair

The invention discloses a multi-working-condition friction-wear test simulation device suitable for a revolute pair. A lifting adjusting mechanism is arranged at the upper part of a rigid frame; the rotation driving execution mechanism is arranged in the middle of the lifting adjusting mechanism, and the pin shaft test piece is installed on the rotation driving execution mechanism; the bending moment loading execution mechanism, the radial positive pressure loading execution mechanism and the heating execution mechanism are arranged at the lower part of the rigid frame in parallel, the bushing test piece is mounted on the bending moment loading execution mechanism, and the bushing test piece is matched with the pin shaft test piece in a sleeving manner; the heating execution mechanism is distributed along the circumferential direction of the bushing test piece; and the radial positive pressure loading execution mechanism is in pushing fit with the bushing test piece. The multi-working-condition friction and w
