Abstract:

An earlier developed multi-body system post-derailment module, that predicts the wheelsets' behaviour after impact with concrete sleepers, is upgraded to account for possible wheel-rail fastener impact situations, after train derailments at high speed. The vertical stiffness describing the wheel-fastener impact behaviour is calibrated and validated based on two authentic derailment cases. Geometrical specifications that permit a brake disc and a bogie frame to act as substitute guidance mechanisms after flange climbing derailments on curved track are presented for an X 2000 trailer car. Further, an introductory analysis on the post-derailment vehicle behaviour on tangent track after a 'flange on rail head' derailment condition is also presented as a function of bogie yaw resistance. The risk of carbody overturning after derailments on tangent track is assessed as a function of coupler height and carbody centre of gravity as well as bogie transversal beam position.
