FATIGUE BEHAVIOR OF FRETTING CRACKS AT THE WHEEL SEAT OF CAR AXLES

Fatigue strength of axles depends on press fits at wheel seats, gear seats and journal bearings. A full-scale axle test machine has been used at the Railway Technical Research Institute for a decade. This paper presents results on fatigue of axles from fretting corrosion and minute cracks at the wheel seat. The effects of fillets, induction hardening and crack depth are reported. Crack propagation and permissible crack depth are now under investigation.
