CEN/TS 13103-3, Railway applications - Wheelsets and bogies - Part 3: Design method for axles with external journals for urban rail
Abstract
This document: - defines the forces and moments to be taken into account with reference to masses, traction and braking conditions; - gives the stress calculation method for axles with internal axle journals; - specifies the maximum permissible stresses to be assumed in calculations for steel grade EA1N defined in EN 13261; - describes the method for determination of the maximum permissible stresses for other steel grades; - determines the diameters for the various sections of the axle and recommends the preferred shapes and transitions to ensure adequate service performance. This document is applicable for: - axles defined in EN 13261 on which are mounted two wheels and - all gauges1 This document is applicable to axles fitted to rolling stock for both Conventional and Urban Rail applications intended to run under normal European conditions. Before using this standard, if there is any doubt as to whether the railway operating conditions are normal, it is necessary to determine whether an additional design factor has to be applied to the maximum permissible stresses. The calculation of wheelsets for special applications (e.g. tamping/lining/levelling machines) may be made according to this standard only for the load cases of freerolling and rolling in train formation. This standard does not apply to workload cases. They are calculated separately. 1) If the gauge is not standard, certain formulae need to be adapted
