Dynamic response analysis of a train?track?bridge (TTB) system is a challenging task for researchers and engineers, partially due to the complicated nature of the wheel?rail interaction (WRI). When Newton?s method is used to solve implicit nonlinear fini...

An improved spatial vehicle?track?bridge interaction system considering the unsupported track is proposed using the virtual work principle. When the track fails to be supported due to the defects under the track, the corresponding bridge?rail connection ...

Based on theoretical and experimental studies, combined retrofit of standard (18-100) freight-car trucks is proposed. This retrofit makes it possible to increase the maximum running speed by 30 to 40 km/h, to extend the service life of damping system ele...
