Three-Dimensional Rail-Bridge Coupling Element of Unequal Lengths for Analyzing Train-Track-Bridge Interaction System

Abstract: A three-dimensional rail-bridge coupling element of unequal lengths in which the length of the rail element is shorter than that of the bridge element is presented in this paper to investigate the spatial dynamic responses of a train-track-bridge interaction system. Formulation of stiffness and damping matrices for the fastener, ballast, and bearing, as well as the three-dimensional equations of motion in matrix form for a train-track-bridge interaction system using the proposed element are derived in detail u… Show more

“…Some material characteristic parameters of the bridge can refer to this paper. 34 Furthermore, the length of every bridge span is 32.6 m, the length between the cross sections of the two bearings is 32 m, and the gap width between the center line of every bridge span is 0.01 m, finally the overall length of rail is 900 m considering the influence of train entering and leaving the bridge, one about 300 m track is added on both sides of bridges, then the train will go from one end of the track to the other. And the height of every pier is 20 m (a average value of high-speed railway pier, and pier height has little influence on TLL and driving performance, so the average value is used for calculation.).…”

“…Based on the FE software Midas, a three-dimensional finite element model of 10-span 32-meter simply supported beam bridge-track-CWR rail is established, including rail, fastening system, sleepers, ballast bed and bridge structure components, as shown in Figure 11a, and the enlarged view in some positions is shown in Figure 11b. Some material characteristic parameters of the bridge can refer to this paper [31], and the specific crosssectional dimensions are shown in Figure 1b. The length of every bridge span is 32.6 m, the length between the cross sections of the two bearings is 32 m, and the gap width between the center line of every bridge span is 0.01 m. Finally, the overall length of the rail is 900 m considering the influence of train entering and leaving the bridge, one about 300 m track is added on both sides of bridges.…”

“…Vehicle-bridge interaction is the key to obtaining the interaction force between the tire and pavement. It has many applications in the weigh-in-motion system , bridge dynamics and vibration control [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50], bridge structural health monitoring, bridge ambient testing, bridge damage identification [51][52][53][54][55][56][57][58][59][60][61][62][63][64], and high-speed railway [29,[65][66][67][68].…”
