“…Tanabe et al , studied numerically the behavior of the Shinkansen trains and railway bridges during earthquakes and checked experimentally part of their results. They also proposed a method to capture numerically the interaction between the wheel and the rail in both the pre‐derailment state and the post‐derailment state, during an earthquake. Ju investigated the derailment of high‐speed trains moving on multi‐span simply supported bridges due to historical earthquake records acting in all three directions.…”

Summary This paper establishes a scheme for the seismic analysis of interacting vehicle–bridge systems. The focus is on (horizontally) curved continuous railway bridges and frequent earthquakes. Main features of the proposed scheme are (i) the treatment of the dynamics in all three dimensions (3D), employing an additional rotating system of reference to describe the dynamics of the vehicles and a realistic 3D bridge model; (ii) the simulation of the creep interaction forces generated by the rolling contact between the wheel and the rail; and (iii) the integration of the proposed scheme with powerful commercial finite element software, during the pre‐processing and post‐processing phases of the analysis. The study brings forward the dynamics of a realistic vehicle–bridge (interacting) system during seismic shaking. For the (vehicle–bridge) case examined, the results verify the favorable damping effect the running vehicles have on the vibration of the deck. By contrast, the study stresses the adverse influence of the earthquake‐induced bridge vibration on the riding comfort but, more importantly, on the safety of the running vehicles. In this context, the paper unveils also a vehicle–bridge–earthquake timing problem, behind the most critical vehicle response, and underlines the need for a probabilistic treatment. Among the 20 sets of historic records examined, the most crucial for the safety of the vehicles are near‐fault ground motions. Finally, the study shows that even frequent earthquakes, of moderate intensity, can threaten the safety of vehicles running on bridges during the ground motion excitation, in accordance with recorded accidents.

“…11) at time t = 1.75 s (with regard to the friction forces of the flange sliding on the railhead) and the vertical reaction arising due to the rail unloading up to 60 kN (under the static pressure P = 82.5 kN) already create a situation critical for safety [30]. Series of numerical experiments (with different accelerograms) and computer simulation of the moving car dimensions and the car wheel reactions can reveal the horizontal maximal relative velocity of the wheel at the moment of derailment and the dynamic pressure on impact of the wheel pair on the holding guide ways [13]. The considered technique allows one to estimate the behavior of the "train-bridge" system by using, for example, special devices which, after the wheel pair derailment, ensure its further motion, as well as the car motion, but already in two-sided holding guide ways.…”

“…This problem can be solved by using (3.1), (3.5), and (4.12) (for the constant values D R i = 1 and D L i = 0) or by using (3.7) and (4.12) for small values of the gap 2 ×Δ. The proposed approach allows the engineers to design original safety traps of the type of holding guide ways [13]. The numerical results illustrated in Figs.…”

Analyzing the action of seismic loads on bridgework is a very topical problem of structure dynamics. These studies combine two independently developing areas of research which include the design of transport structures only for seismic loads [1][2][3][4][5][6][7][8][9][10][11][12][13][14] and the design of structures for the action of inertial moving load [15][16][17][18][19][20][21][22][23][24][25][26][27][28]. In this paper, a numerical method for studying vibrations of framed structures modeling bridges under the action of seismic loads is proposed. At the first stage, we use a method based on the use of rod boundary elements (BEM) and intended for designing building structures which only experience seismic loads given by accelerograms. At the second stage, a technique for estimating the interaction between the bridge span and the moving load due to the rolling stock entering the bridge under seismic actions is developed.

Train post-derailment behaviours and containment methods: a review

Railway accidents, particularly serious derailments, can lead to catastrophic consequences. Therefore, it is essential to prevent derailment escalation to reduce the likelihood of severe derailments. Train post-derailment behaviours and containment methods play a critical role in preventing derailment escalation and providing passive safety protection and accident prevention in the event of a derailment. However, despite the increasing attention on this field from academia and industry in recent years, there is a lack of systematic exploration and summarization of emerging applications and containment methods in train post-derailment research. For this reason, this paper presents a comprehensive review of existing studies on train post-derailment behaviours, encompassing various topics such as post-derailment contact–impact models, dynamic modelling and simulation techniques, and the primary factors influencing post-derailment behaviours. Significantly, this review introduces and elucidates substitute guidance mechanisms (SGMs), which serve as railway-specific passive safety protection and accident prevention measures. The various types of SGMs are depicted, and their ongoing developments and applications are explored in depth. The review additionally points out several unresolved challenges including the adverse effects of SGMs, and proposes future research directions to advance the theoretical understanding and practical application of train post-derailment behaviours and containment methods. This review seeks to be a valuable reference for railway industry professionals in preventing catastrophic derailment consequences through post-derailment containment methods.
