D () sets servo electric jar A (13) threaded rod, the alternation of servo electric jar B (7) threaded rod by computer-controlled program Displacement amplitude, it is thus achieved that load steel wire rope (27) and anti-fatigue steel under the corrosion fatigue load of anti-fatigue steel cord (22) and etching condition Dynamic alternation contact load between cord (22), records anti-fatigue steel cord (22) corrosion fatigue load with pulling force sensor (17) Change, obtain with 2 D force sensor (6) and load moving between steel wire rope (27) and anti-fatigue steel cord (22) under etching condition State contact load and frictional force, by the electrochemistry of steel wire rope in electrochemical workstation (11) real time record fretting corrosion fatigue process Etching characteristic, by the temperature of temperature switch board real time record etchant solution;
E () is stretched by change temperature, etchant solution, servo electric jar A (13) telescopic displacement and frequency, servo electric jar B (7) Displacement and frequency, it is achieved the steel wire rope fatigue under scrubbing experiment under different temperatures, acid-base value and dynamic Contact load coupling condition;
F () experiment terminates after, cooling water pipe (3) is passed through cooling water, when etchant solution temperature drops to suitable temperature, reclaims corrosion Solution the change of test experience post-etching solution component.
