ANALYTICAL CALCULATION OF STRENGTH OF FREIGHT WAGON AXLE IN ACCORDANCE WITH EUROPEAN STANDARDS

Milan Bižić, Dragan Petrović

This paper presents a methodology for analytical calculation of strength of

freight wagon axle in accordance with European standards. The axle of standard freight

wheelset for normal track gauge and axle-load of 22.5 t was considered. The authoritative

loads of the axle, which originate from vehicle mass and braking, are discussed and analyzed.

The principal scheme of loads of axle is given as well as the way of determination of

quantitative values of all loads in accordance with European standards. The procedure of

determination of operating and allowable stresses and proving the axle strength was

performed and exposed. The obtained results are verified by the results of numerical

calculation performed in Ansys software package.
