“…Slab track performance was compared to a ballasted track using 2D FEM analysis in Ref. [85], and the results showed that the slab track reduced train-induced vibrations and track level displacements by almost 50% when compared to the ballasted track. The performance of the slab track was studied with a prototype fatigue test considering cycling load, temperature variation, and water erosion in Ref.…”

Higher train speeds and heavier axle loads trigger elevated stresses and vibrations in the track, potentially increasing track deterioration rates and maintenance costs. Alternative track forms made of combinations of reinforced concrete and asphalt layers have been developed. A thorough understanding of the slab and asphalt tracks is needed to investigate track performance. Thus, analytical and numerical models have been developed and validated by many researchers. This paper reviews numerical models developed to investigate railway track performance. The synthesis of major finite element models is described in detail, highlighting the main components and their outputs. For slab track models, the use of a structural asphalt layer within the railway track remains an active research topic and firm conclusions on its efficacy are not yet available. It can be expected that slab track structures will also be affected by train-induced ground vibrations. There is thus a gap in the literature regarding the measurement of dynamic effects on high-speed railway lines, and further research is needed to investigate the dynamic behaviour of slab–asphalt track systems. In this review, novel solutions for mitigating the vibrations in high-speed rail are discussed and compared. The use of asphalt material in railways appears to have beneficial effects, such as increasing the bearing capacity and stiffness of the structure and improving its dynamic performance and responses, particularly under high-speed train loads.

“…This developmental trend requires a new strategy to improve vibration protection inside and outside moving trains, especially in the infra-low-frequency range, f ¼ 1À40 Hz, which is the most harmful for human health and work activity [15]. The rail transport generates complex vibrations [15][16][17][18], some of which are increased at higher speeds of a moving train. Figure 1.3 shows the data measured on the ground within a radius of 7.5 m from ballasted track when a train passed at speeds of 70 and 200 kph [18].…”

Design and deploy advanced vibration protection systems based on elastic composites under post-buckling, with this essential reference. Methods for designing vibration protection systems with negative and quasi-zero stiffness are formulated, explained, and demonstrated in practice. All key steps of the system design are covered, including the type and number synthesis, modelling and studying of stress-strain state under post-buckling of elastic composite designs, chaotic dynamics and stability conditions, real-time dimensioning, and active motion control. In addition to coverage of underlying theory, the use in helicopters, buses, railroad vehicles, construction equipment and agricultural machinery are included. An excellent reference for researchers and practicing engineers, as well as a tutorial for university students and professors with an interest in study, development and application of alternative methods of vibration protection anywhere.
