The paper describes the numerical simulation of the vertical random vibration of train-slab track-bridge interaction system by means of finite element method and pseudoexcitation method.
Each vehicle is modeled as four-wheelset mass-spring-damper system with two-layer suspension systems.
The rail, slab, and bridge girder are modeled by three-layer elastic Bernoulli-Euler beams connected with each other by spring and damper elements.
The equations of motion for the entire system are derived according to energy principle.
By regarding rail irregularity as a series of multipoint, different-phase random excitations, the random load vectors of the equations of motion are obtained by pseudoexcitation method.
Taking a nine-span simply supported beam bridge traveled by a train consisting of 8 vehicles as an example, the vertical random vibration responses of the system are investigated.
Firstly, the suitable number of discrete frequencies of rail irregularity is obtained by numerical experimentations.
Secondly, the reliability and efficiency of pseudoexcitation method are verified through comparison with Monte Carlo method.
Thirdly, the random vibration characteristics of train-slab track-bridge interaction system are analyzed by pseudoexcitation method.
Finally, applying the 3σ rule for Gaussian stochastic process, the maximum responses of train-slab track-bridge interaction system with respect to various train speeds are studied.
