Railway applications — Strength assessment of rail vehicle structures — Part 3: Fatigue prEN 17149-3 rev

Scope

This document describes a procedure for fatigue strength assessment of rail vehicle structures. It is part of a series of standards that specifies procedures for strength assessments of structures of rail vehicles that are manufactured, operated and maintained in accordance with standards valid for railway applications.
This document is applicable for load data with total number of cycles higher than 10 000 cycles.
The assessment procedure is restricted to ferrous materials and aluminium.
This document does not define design load cases.
This document is not applicable for corrosive conditions or elevated temperature operation in the creep range.
This series of standards is applicable to all kinds of rail vehicles. However, it does not define in which cases a fatigue strength assessment is to be undertaken.
