“…Based on the principle of virtual work, their inertia force, damping force, elastic force and the corresponding virtual work can be calculated easily when vehicles run on the bridge. The mass matrix, stiffness matrix and damping matrix of the vehicle-bridge coupling system can be obtained ultimately according to the law of "condemnation" [7] .…”

The vehicle and TMD were modeled as a combination of several rigid bodies, which were connected together by a series of springs and dampers, the bridge was modeled by beam elements, and thus the spatial vibration equation of the system of TMD, vehicle and bridge was established, which was solved by direct integral method. A highway and railway bi-purpose cable-stayed bridge was taken as an example, the spatial vibration responses were calculated when the train and car run through the bridge, and the influence of TMD on the vibration response was discussed. The results show that the bridge has the sufficient lateral and vertical stiffness, the train and car affect each other when they cross the bridge at the same time, and TMD can play a good role in controlling the vibration response of long span cable-stayed bridge-train-car coupling system.

“…Many studies have shown that with increase of bridge span and moving loads on the bridge, the interaction between the bridge and moving trains become more of concern. Although many investigations have been done in the field, most of them focus on the single-line or double-line railway bridges [1][2][3][4]. Few studies have been published in terms of multi-line railway train-bridge interaction system.…”

This paper investigates the dynamic properties of each sub-system of a coupled railway train-bridge interaction system. Both spatial beam-plate model and spatial grillage model are built for a long-span dual-deck cable-stayed railway bridge by use of finite element method. The railway train is modeled as a mass-spring-damper system. Then free vibration equations are established based on the finite element models and then subspace iteration method is employed to calculate the dynamic properties for each sub-system. Results show that the spatial grillage model agrees well with the spatial beam-plate model in terms of mass and stiffness distribution. The spatial beam-plate model serves as benchmark solution and the grillage model as a tool for dynamic responses of the coupled system due to its computational efficiency. It also shows that first modes of both the railway train and long-span bridge are lateral direction, which indicates that the train may experience much response in lateral direction. Therefore attention should be drawn to the lateral running stability and safety of railway train due to the coupling effect between the bridge and railway train.

“…Most researchers has calculated the vibration responses of the train-bridge system and evaluated the running safety of train with derailment coefficient and wheel load reduction rate. By means of running smoothness and comfort index, the running smoothness and comfort of train has been also evaluated [1,2,3]. In Soviet Union, the limit values of basic natural period for bridges have been established with the operation criteria for vehicle [1].…”

The running performance of train on Hubian bridge was analyzed with energy random analysis theory for derailment. The calculated result shows that the running safety of train cannot be ensured with the existing operation condition, and the measurement of rate-limiting or reinforcement is needed to be taken for this bridge. A method for establishing index of traffic safety for railway bridge was proposed. The detailed contents of the method are as follows. The lateral amplitude on the middle of beam is determined as index for traffic safety for beam-pier system. The critical beam-pier system with which the running performance of train can be guaranteed is determined. The lateral amplitude of critical beam-pier system is calculated and determined as limit value for traffic safety. The limit value of lateral amplitude for traffic safety for Hubian bridge is determined as L/6400.
