VIBRATION DYNAMICS OF RAIL AXLES

DINAMICA VIBRAZIONALE DELLE SALE FERROVIARIE

First, the dynamic configuration of an axle, generated by forced vertical excitation of the two wheels, is considered. A mathematical model of the vehicle and the axle vibrations is derived and analyzed. The frequencies of the axle are determined with the variation of the characteristic parameters of the vehicles and of the axles themselves. In the second part of the article, the dynamic stresses are sought, generated by typical excitation of the line and acting on the axle with the variation of the speed of the vehicle, in order to achieve optimum design.
