STUDY ON THE RESIDUAL STRESSES IN RAILROAD SOLID WHEELS AND THEIR EFFECT ON WHEEL FRACTURE

Residual stresses in two types of wheel were measured by the X-ray method and by the method of taking samples from the rim surface, while the thermal stresses produced in service were simulated by test bench braking and calculated by the finite element method. The brakes were applied until cracks appeared and their spread was studied according to the laws of fracture mechanics. The authors draw conclusions on the conditions in which superficial cracks can lead to wheel fracture.
