Analytical calculation of hollow railway axle in accordance with EN 13103

Abstract

The paper presents methodology for analytical strength calculation of hollow axles of railway vehicles. The considered methodology is defined by appropriate international standard EN 13103. The calculation procedure is demonstrated on the concrete example of hollow axle for axle load of 25 tons, and for normal track gauge of 1435 mm. Based on the appropriate authoritative loads, the equivalent stresses in the selected characteristic sections of the axle are determined. They should be compared with the corresponding permissible stresses for the considered sections of hollow axle determined on the basis of the endurance limits in certain sections and the corresponding safety factors. The results of the paper can be very useful for all those who deal with design and optimization of hollow axles of railway vehicles.
