Experimental Investigation of Fretting Fatigue of Train Axles under Rotating Bending
In railway transportation, the press fit of wheel and axle is typically causing fretting damage and it is also an important issue relative to the safety of railway. To examine the fretting damage of the interference fit of wheel and axle the fretting fatigue test under 4-point rotating bending loads is carried out based on samples, as well as the fretting fatigue damage rule is studied. The test results show that the fretting causes the fatigue limit to decrease significantly and all of the fracture sections occur at the contact edges of the fitting zone with the sleeve.
