Railway applications - Wheelsets and bogies - Monobloc Wheels - Technical approval procedure - Part 1: Forged and rolled wheels
The aim of this document is to define a design assessment procedure of a forged and rolled monobloc wheel (RST). This assessment is made before entry into service. This document describes, in particular, the assessment to be performed in order to use wheels on a European network which, moreover, have quality requirements in conformity with those defined in EN 13262. This assessment requires that the conditions of use of the wheel are defined and this standard provides a method for the definition of those conditions. The design assessment has four different aspects: - a geometrical aspect: to allow interchangeability of different solutions for the same application; - a thermomechanical aspect: to manage wheel deformations and to ensure that braking will not cause wheels to fracture; - a mechanical aspect: to ensure that no fatigue cracks occur in the wheel web and that no permanent deformation occurs under exceptional loading; - an acoustic aspect: to ensure that the solution chosen is as good as the reference wheel. This document does not cover assessment of the hub and the ri
