Analysis of Dynamic Behavior for Slab Track of High-Speed Railway Based on Vehicle and Track Elements

Non-stationary random vibration of a coupled vehicle–slab track system using a parallel algorithm based on the pseudo excitation method

“…According to equations (1), (2) and (3), the equation of motion for the coupled vehicle-slab track system can be written as…”

A numerical study on the fatigue life design of concrete slabs for railway tracks

“…Studies on the former are concentrated on the vehicle-track-subgrade coupling [19,20,13,7,18]. For example, Tanabe et al [19] analysed the dynamic interaction between the Shinkansen train (through multi-body dynamics employing non-linear springs and dampers) and the railway structure (consisting of truss, beam, shell and solid elements).…”

“…Slab track, also called ballastless track, is a modern form of track construction which has been successfully used around the world for high speed lines, heavy rail, light rail and tram systems [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Such a trend is mainly attributed to the fact that slab track systems have numerous structural and operational advantages compared with the traditional ballasted track.…”

Effect of track irregularity on the dynamic response of a slab track under a high-speed train based on the composite track element method

“…The maximum vertical static displacements and the maximum dynamic displacements of the rail and the slab were compared. Lei and Zhang [15] proposed the vehicle and track elements method to study the dynamic behaviour of the CRTS II slab track in high-speed railways in China. In this method, the entire vehicle was considered as a special element, a massless rail beam modelled the wheel-rail interaction, and the track was considered as a composite beam element on a continuous elastic foundation consisting of the rail, slab and concrete base layers.…”
