Railway Applications - Fatigue strength assessment of railway vehicle structures based on cumulative damage prEN 17149

Scope

The purpose of this European standard is to specify the procedure for fatigue strength assessment of railway vehicle structures based on cumulative damage.
This document is applicable to all rail vehicle structures, which are covered by EN 12663 series (car body) and EN 13749 (bogie frame).
It considers materials used for design of car bodies and bogie frames (steel, aluminum, castings and forgings) and the manufacturing according to the standards valid for railway applications.
Note As a manufacturing standard, EN 15085 series covers the welding of rail vehicle structures.
It is applicable for variable amplitude load data with total number of cycles higher than 10000 cycles.
This document is not applicable for:
- Corrosive conditions or
- Elevated temperature operation in the creep range.
A static strength assessment is outside the scope of this European Standard.
