Numerical analysis of engineered metabarrier effect on ground vibration induced by underground high-speed train

Shuai Qu et al.

Summary: This study investigates the impact of the underground section of the Chengdu-Zigong high-speed railway on vibration-sensitive equipment and explores the effectiveness of an engineered metabarrier in reducing ground vibration. The results show that horizontal vibrations cannot be ignored and the metabarrier can effectively attenuate ground vibration, with the attenuation rate stabilizing as the depth of the metabarrier increases.

Field measurement and evaluation of vibrations inside buildings above metro tunnels

Honggui Di et al.

Summary: The development of buildings above metro tunnels in China has been rapid in recent years due to the utilization of land resources. However, these buildings are more susceptible to train-induced vibrations, which adversely affect the living quality of occupants. This study investigated the response characteristics of train-induced vibrations at the basement and floor slabs of buildings based on field-measured vibration data. The results showed that the vertical acceleration was greater than the horizontal acceleration, with the main frequency band of vertical vibration being 50-70 Hz.

Parameter optimization of a new cone-oriented elastic side-supporting long sleeper damping track: Experiment and simulation

Yukui Wang et al.

Summary: In this paper, a novel cone-oriented elastic sidesupporting long sleeper damping track (COESSLSDT) is proposed to reduce train-induced vibration and noise. The mechanical performance of the COESSLSDT was obtained through finite element analysis and validated in the field. The effects of key structural parameters of the COESSLSDT were evaluated, and the influence of side and bottom supports on the dynamic responses of the track structure was studied.

Effect of longitudinally varying characteristics of soil on metro train-induced ground vibrations based on wave propagation analysis

Lihui Xu et al.

Summary: A new model based on wave propagation analysis was proposed to address the issue of longitudinally varying characteristics of soil layers around metro tunnels, improving prediction accuracy. Results showed that the amplification and reduction of transfer loss due to the variation in longitudinal soil characteristics occur at specific frequencies.

Resonance of railway vehicles induced by floating-slab tracks: mechanism and countermeasures

Peibin Jiang et al.

Summary: This paper investigates the resonance phenomenon of a metro vehicle induced by eccentric wheels travelling on FS tracks. The study reveals that resonance caused by eccentric wheels is the root cause for the reduction of ride comfort of metro vehicles. Field tests confirm that re-profiling eccentric wheels can significantly eliminate the resonance phenomenon and enhance vehicle dynamics performance.

Theoretical and experimental study on vibration reduction and frequency tuning of a new damped-sleeper track

Zhenxing He et al.

Summary: In this study, a new elastic side-supporting long sleeper damping track (ESSDT) is proposed, along with a novel vibration reduction and frequency modulation device (VRFMD), to improve the vibration damping performance and structural stability of the track system. The results show that by modifying the parameters of the VRFMD, the vibration of the track and the transmission of vibration to the foundation can be effectively reduced, and the natural frequency of the track can be adjusted to avoid wheel-rail contact resonance.

Impact vibration behavior of railway vehicles: a state-of-the-art overview

Lin Jing et al.

Summary: This paper provides a comprehensive overview of recent studies on the impact vibration behavior of railway vehicles, categorizing sources of impact excitations, introducing research approaches of vehicle impact vibration, and examining impact vibration response characteristics. The results show that excessive vibrations of railway vehicles induced by dynamic impact loadings have a significant impact on train operating safety and stability, which are difficult to eliminate due to the complexity and diversity of railway lines and service environment.
