Opis:: Railway line capacity is growing in importance as a criterion for the assessment of railroad infrastructure performance. This problem is becoming more and more relevant as the demand for rail transport increases, especially considering the transport policy related to the promotion of climate-neutral means of transport. Insufficient capacity affects the stability and reliability of railway traffic operations. The analytical methods used for capacity estimation are typically insufficient to solve problems of a multicriteria nature (i.e. problems which take traffic heterogeneity and human factors into account). Optimisation methods, on the other hand, usually yield the best results if the current timetable for a given line is known. Additionally, they do not strongly consider the impact of the running characteristics of a specific train type and of the system or several systems in operation on the line (e.g. national Class B system and ERTMS/ETCS system). Therefore, this paper proposes a model and a simulation program developed in the Matlab and Simulink environment to be used to simulate on-route train movement, to study railroad capacity with different control systems, as well as for predictive train control to minimise energy losses. The authors described the assumptions adopted for the simulation program and the input parameters configurable against a specific line segment. They also discussed selected results derived from simulations of controlling the departure of trains to a railway line with the purpose of energy loss reduction.

Opis:: The paper develops a methodology of FE modelling and simulation of the bridge - track - moving train (BTT) system using LS-DYNA computer code. The KNI 140070 viaduct of span length 14.40 m with ballasted track was selected as a representative for the study. Two variants of the viaduct were taken into consideration - a version operated before the modernization in 2008 and the modernized version including additional flats welded to the bottom flanges of the main beams. The German high-speed train ICE-3 moving at 150–300 km/h was selected. The FE model of the BTT system was developed using Altair HyperMesh and LS-PrePost software. The platform of the viaduct was modelled using 8-node 48 DOF solid elements. The structure was symmetrised, homogenized and reflected by linear viscoelastic orthotropic materials. Discrete model of the track included the main and side rails, fastening systems, sleepers, crushed stone ballast and approach RC slabs. Components of the train FE model were considered as rigid bodies. Cylindrical and revolute constrained joints were applied for kinematic connections and relations between respective components. Discrete springs and dampers were applied for FE modelling of the primary and the secondary suspension systems. Numerical simulations were focused on determining the resonant velocities for both considered variants. Selected time histories for displacements and stresses, were shown as the results of the analyses.

Opis:: The paper develops a new methodology of FE modelling and simulation of the bridge - track - moving train system with the use of CAE systems. The KNI 140070 viaduct of span length 14.40 m, located on the Polish Central Main Line, has been selected. The modernized track contains: 60E1 main rails equipped with Vossloh 300-1 fasteners, 60E1 side rails with SB3 fasteners, B 320 U60 sleepers, crushed stone ballast, approach RC slabs. A KTX (Korea Train eXpress) high-speed train, being a modification of a TGV train, is taken into consideration. A methodology of physical and numerical modelling of the viaduct, the track and the train was developed using Altair HyperMesh and LS-PrePost software. The FE model of a bridge superstructure consists of 4-node shell elements (main beams) and 8-node 48 DOF solid elements (reinforced concrete platform). RAIL TRACK and RAIL TRAIN modules available in LS-Dyna system were applied for simulating the train — trach interaction. Hughes-Liu beam elements were used for the rail modelling. Rail fastenings were simulated using one-dimensional discrete spring and damper elements. Carbodies, bogieframes and wheelsets were considered as rigid bodies and they were modelled using shell and beam elements. Cylindrical and revolute constrained joints and discrete springs and dampers were applied to connect all components of the FE model of rail-vehicles. The exemplary simulation of transient vibrations of the bridge - trach -train system has been made for service velocity 300 km/h. Contours of displacement and stress and selected time histories for displacements, accelerations and stresses, created in LS-PrePost and HyperView software, have been analysed.

Opis:: Railway traffic simulation, taking into account operation and maintenance conditions, is not a new issue in the literature. External effects in such networks (e.g. level crossings) were not taken into account in studies. The used models do not take into account sufficiently the process of degradation and recovery of the network. From the technical side, currently carried out simulations are made using similar approaches and techniques as in the initial stage of research. Well-established work in this area could be the basis for evaluation of new solutions. However, the progress in simulation tools during the last years, especially in performance and programming architecture, attempts to create a modern simulation tool. In the paper were presented the main assumptions for the evaluated event-based simulation method, with application to stiff-track transportation networks.

Opis:: The paper presents a methodology of finite element (FE) modelling and simulation of the bridge – track – moving high-speed train system using CAE systems. Two composite (reinforce-concrete – steel) bridges were considered. The span length was equal to 15 and 21 meters, respectively. Bridges selected for the study belong to the proposed series of bridges with the span length of 15 to 27 meters stepped by 3 meters. Full symmetry of the bridges was assumed. RC platform was homogenized since the rebars were distributed quasi-uniformly in the specified platform sections. The FE model of a bridge superstructure consisted of 4-node shell elements (main beams) and 8-node 48 DOF solid elements (reinforced concrete platform). RAIL_TRACK and RAIL_TRAIN LS-DYNA’s modules were applied for simulating the moving train – track interaction. Ballasted track with the rectilinear rail-line axis was taken into consideration. German ICE-3 train running at velocity of 200–300 km/h was selected as a representative for the study. All mass components of the train FE model were treated as rigid bodies. Symmetric vibrations of the train units were assumed with respect to the main longitudinal vertical plane of symmetry of the system. Nodal displacement and longitudinal normal stress in shell elements were registered during the FE analysis. The results were depicted in the form of time histories for selected velocities. In addition, extreme values of vertical deflections and normal stress were compiled and presented a function of train velocity. It allowed to assess the dynamic response of the bridge depending on its span length. Contours of resultant displacement for the RC platform was also presented.

Opis:: Based on the one-dimensional quasi-exact physical and mathematical modelling of a composite (steel-concrete) bridge/track structure/high-speed train system (BTT), developed in Part 2, advanced computer algorithms for the BTT numerical modelling and simulation as well as a computer programme to simulate vertical vibrations of BTT systems are developed. The exemplary bridge under numerical quasi-static and dynamic analysis, designed according to Polish standards, has a 15.00 m span length and belongs to the SCB series-of-types developed in Part 1. The bridge is loaded by a German ICE-3 high-speed train moving at the resonant and maximum operating speeds. A continuously welded ballasted track structure adapted to high operating velocities is applied. The output quantities include: time-histories of the vertical deflection of the main beams at the midspan, time-histories of the longitudinal normal stress in the bottom fibres of the main beams at the midspan, time-histories of the vertical acceleration of the bridge deck at the midspan, time-histories of the vertical accelerations of the suspension pivots in car-bodies, time-histories of the dynamic pressures of the wheel sets of moving rail-vehicles. The design quantities, understood as the extreme values of the output quantities, are used to verify the design conditions. The basic random factor, i.e. vertical track irregularities of the track, is taken into consideration. Basic statistics of the design quantities treated as random variables are calculated and taken into account in the design conditions.

Opis:: This paper presents the theory about generating the braking curve and the analysis of the influence of the braking controller parameters on the generation of the braking curve of the train. In this paper, computed examples of braking quality developed using generic quality factor are shown, and on the basis of the calculations, weight components of the factor and an additional criterion for assessing the quality of braking were proposed. It has been demonstrated that the developed algorithms can be used to verify the effectiveness of the braking controller and the adjustment of the terms, and the change of these algorithms affects the shape of the generated braking curve of the train. It has been shown that the analysis of a failure of the propulsion car revealed the existence of a safe braking area. The performed statistical analysis confirmed the normal distribution of the scatter of braking results, for which the regression model fitted.
