BENDING STRESSES IN A MOTORED AXLE ON ELECTRIC ROLLING STOCK--1

This article gives results of strain gauge tests on a motored axle both empty and loaded. Deductions from the results lead to an emphasis on the transverse friction between wheel and rail. This factor, neglected in axle stress formulae, is shown to be of major importance in the bending moment on the wheel seat of an axle, amounting to about 40 percent of the total on a curve with equilibrium cant. Support for the deduced theory is given by the correspondence between calculated and measured stresses, and also by the results of direct comparative tests. Additional stresses from cant deficiency, track irregularities, and acceleration or braking are discussed. The apparatus used in the test and the procedure of testing are fully described.
