- •
A three-dimensional model of train–slab track–bridge coupling system is established.
- •
The three-dimensional equations of motion for the interaction system consisting of a moving train, slab track, and bridge are derived.
- •
The excitations between a wheel and rail are formulated by the pseudo-excitation method.
- •
An approach with greater efficiency and accuracy to evaluating the random vibration characteristics of the system is presented.
