The invention relates to test equipment for a friction coefficient, and belongs to the field of simulating test machines. The problem is solved that an existing test machine for the friction coefficient cannot accurately predict the service life of a submarine cable. In the adopted technical scheme, the test equipment for the friction coefficient comprises a rack and a driving mechanism, a mediumpart is arranged on the rack, the driving mechanism comprises a servo loading unit, a first pull rope and a second pull rope, the first pull rope and the second pull rope are detachably connected to ato-be-tested part separately through a clamp, and when the first pull rope and the second pull rope are connected to the to-be-tested part and the servo loading unit makes the to-be-tested part movethrough reciprocation, the to-be-tested part is abraded by the medium part; when the first pull rope or the second pull rope is connected to the to-be-tested part, the servo loading unit drives the to-be-tested part to move in a single direction, the to-be-tested part is rubbed by the medium part. Through the servo loading unit, the to-be-tested part is rubbed and/or abraded by the medium part, reliable data is provided when the service life of the submarine cable is predicted.
