Abstract: Tension-torsion fretting corrosion fatigue is one of main failure modes of hoisting rope in the deep coal mine.
The vibration frequency of hoisting rope in the deep coal mine determines the fretting frequency between steel wires,
directly affects the tension-torsion fretting corrosion fatigue mechanism and damage degree of steel wire, and thereby
restricts the service safety of hoisting rope in the deep coal mine. In the present study, the self-made tension-torsion
fretting corrosion fatigue testing rig was employed to conduct tension-torsion fretting corrosion fatigue tests of steel
wires in the acid electrolyte solution. Hysteresis loops of tangential force versus displacement amplitude and torque
