Analysis and improvement of railway crossing performance using numerical and experimental approach: application to 1:9 double crossovers

The paper presents an integrated approach for analysis and improvement of performance of railway crossings. The approach consists of a detailed finite element (FE) model of a wheel rolling over a crossing (validated against the measured crossing accelerations) and experimental tools installed on the crossings in situ. The studied crossings are...

Rail surface crack initiation analysis using multi-scale coupling approach

A concurrent multi-scale computational strategy for rail surface crack initiation analysis is introduced in current paper. It attempts to take advantage of the efficiency of macroscopic models and the accuracy of the mesoscopic models. The solving procedure is, through the coupling of individual approaches, beginning from the largest scale to...
