Dynamic alternation contact load between cord (22) records tired steel wire rope (22) corrosion fatigue load with pulling force sensor (17)
Variation, obtain moving between load steel wire rope (27) and tired steel wire rope (22) under etching condition with 2 D force sensor (6)
State contact load and frictional force, with the electrochemistry of steel wire rope in electrochemical workstation (11) in real time record fretting corrosion fatigue process
Etching characteristic records the temperature of etchant solution with temperature switch board in real time；
(e) flexible by change temperature, etchant solution, servo electric jar A (13) telescopic displacements and frequency, servo electric jar B (7)
Displacement and frequency realize the steel wire rope fatigue under scrubbing experiment under different temperatures, acid-base value and dynamic Contact load coupling condition；
(f) after testing, cooling water pipe (3) is passed through cooling water, when etchant solution temperature drops to suitable temperature, recycling corrosion
