Abstract

The paper considers two methods of modelling a Y25 equipped freight wagon. The wagon was modelled in full, with all Lenoir links, spring carriers and plungers as separate bodies. The second was a simplified model which represented the behaviour of the Lenoir links using stiffnesses, bumpstops and friction elements only. The models were compared against industry standard assessments for derailment risk (wheel off-loading (ΔQ/Q), flange climb derailment (Y/Q) and cyclic top) as well as stability and curving performance. The analysis showed that the two modelling approaches gave comparable results with good agreement vertically. However, the study has highlighted that the representation of plan view behaviour of the models differed, particularly for stability.
