THE QUESTION OF SIZE FACTORS IN CALCULATING THE STRENGTH OF RAILWAY WHEEL-SET AXLES

BEITRAG ZUR FRAGE DES GROSSENEINFLUSSES BESONDERS BEI ACHSWELLEN VON EISENBAHNRADSATZEN

Numerous indications are given in technical literature about the decrease in the bending strength of axles in relation to an increase in size, but the views are widely divergent. This article considers the size factors or coefficients to be used in calculating the strength of shafts or axles subject to bending reversal stresses, and attempts to correlate the various findings to clarify these theoretical considerations. The influence of other factors such as the geometry of the axle, and also the technology of heat treatment of the steels, is included. The effects of the pressing on of wheels on to the wheel seat of the axle, and the notch effects in the geometry must also be considered in determining the strength of axles.
