The utility model relates to a holding device for a contact chafing fatigue experiment, which comprises a load bearing frame, a pair of a load head support racks which are arranged oppositely and a pair of load heads which are respectively arranged on the load head support racks in a slide manner, wherein the pair of load heads are arranged symmetrically and the sliding shafts of the load heads are horizontal and on the same line; overhang weight fixed pins are symmetrically arranged on each load head along the two sides of the slide axle; each overhang weight fixed pin is connected with a steel rope, and the other end of the steel rope is provided with a weight; and a group of force application components are formed by the overhang weight fixed pins respectively arranged on the load head and located at the same side of the slide shaft and the steel rope and the weight connected to the overhang weight fixed pins; and in each group of force application components, the steel rope connected with one load head is wound on the overhang weight fixed pin on the other load head so that one end of the steel rope connected with the weight vertically hangs. The holding device has simple structure, is convenient to use, and can be matched with a single-shaft fatigue experiment machine so as to complete the contact chafing fatigue experiment..
