Special Issue Information

Dear Colleagues,

The dynamics of railway vehicles play a crucial role in the overall safety, reliability, and competitiveness of railway systems. The new paradigms of virtual homologation and the recent trends in artificial intelligence techniques have thrusted works in the field, allowing us to explore a wide range of solutions with a significant reduction in testing times. At the same time, the relevance of experimental tests is still unmatched, as numerical models should always be experimentally validated.

The Applied Sciences journal has launched a new Special Issue entitled “Railway Vehicle Dynamics”, aiming to collect scientifically relevant contributions that can bring innovation to the field, addressing several topics including (but not limited to) running stability, safety, traction/braking operations, curving behavior, vibrations, comfort, and wheel–rail contact analysis. Papers should focus on the implementation of numerical/experimental techniques with the aim of optimizing the running dynamics of railway vehicles or improving the current knowledge on the complex relationship between vehicle dynamics and associated phenomena. The Special Issue welcomes papers dealing with different application frameworks, including the following:

  • Design of the main vehicle components;
  • Development of control logics for optimization of traction/braking or curving behavior;
  • Monitoring systems/algorithms for enhanced safety and stability.

The presented research is focused on a proposal to improve a tank container structure by introducing sandwich components in the bottom to reduce its load while transported by rail. This solution will help to reduce loads by means of the energy-absorbing material included in the sandwich components. The proposed improvement is substantiated with mathematical modeling of the dynamic load of the tank container. It is found that the use of sandwich components in its structure can reduce the dynamic load by 12 to 18%, depending on the characteristics of the energy-absorbing material. This study also includes computer modeling of the dynamic load on the tank container, which makes it possible to identify the acceleration distribution fields acting on the tank container, and to determine their numerical values. The mathematical model of the dynamic load of the tank container is verified. Fisher’s exact test was used. The coefficient of determination was 0.81. The calculation was performed within the confidence interval from −0.95 to +0.95. It is found that the hypothesis of the adequacy for the model is not rejected. The study also includes a modal analysis of the tank container. The results of the modal analysis revealed that the safe operation of the tank container during transportation is ensured, as the first eigenfrequency is 13.8 Hz. The achieved results can be used for developing modern tank container designs. Full article

In this paper, a model-based approach for the identification of the railway vertical track alignment from simulation data is presented. The proposed methodology is based on the application of the unknown input observer algorithm. The model of a conventional train is used to simulate the acceleration levels that vehicle-mounted sensors (e.g., on the bogies and carbody) would measure during operation. Simulations are carried out at a constant speed on both straight and curved tracks, including different types of track geometry components (namely longitudinal level, alignment, and cross-level) to assess the algorithm capability to identify the input irregularity. The primary focus is on the identification of mean vertical track alignment, a critical irregularity component for safety issues. In the analysed cases, the comparison between the measured and reconstructed signal histories are quite satisfactory, with maximum errors in the order of 15% and 29% along straight and curved tracks. Comparing the frequency content of the signals, a significantly higher degree of accuracy is observed (with maximum errors of 5–10% depending on the track layout), which demonstrates that the proposed methodology is suitable for track irregularity identification and monitoring purposes using an instrumented vehicle.
