Safe Life and Damage Tolerance Concepts of Railway Axles
On July 9,2008 a high speed train derailed in Cologne main station,Germany at a low speed because an axle was broken.Fortunately,the derailment happened at a low speed so that nobody was injured.The reason for the broken axle was investigated and it turned out that most likely large inclusions located shortly underneath the surface in a T-transition were the origin of the final crack.Basing on that result,a systematic investigation on existing safety assessments of railway axles was performed.This results in an analysis of the production process of axles and in a critical review of existing of existing assessments.Improvements and future developments are outlined.
