Analytical calculation of strength of freight wagon axle in accordance with European standards

Abstract

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.
