Near-Surface Characterization Using High-Speed Train Seismic Data Recorded by a Distributed Acoustic Sensing Array

IEEE Transactions on Geoscience and Remote Sensing, 2022
A high-speed train can be regarded as a moving seismic source when it travels along a railway. Seismic waves from such sources have strong energy and can be used for near-surface characterization, safety monitoring of high-speed railways, and detection ...

High-speed train wheel set bearing fault diagnosis and prognostics: A new prognostic model based on extendable useful life

, 2021
Diagnosis and prognostics of rolling element bearings have been widely studied in recent years, but very few researches were dealing with high-speed train wheel set bearings (HSTWSB).

High-Speed Train Positioning Using Deep Kalman Filter With 5G NR Signals

IEEE transactions on intelligent transportation systems (Print), 2022
Positioning is the most basic yet important process in a train control system. In practical train systems, the position of a train is determined with a track circuit, a radio frequency (RF) tag called a “balise”, or a tachometer.

The effects of the friction block shape on the tribological and dynamical behaviours of high-speed train brakes

, 2021
Drag brake experiments using hexagonal, pentagonal, and circular friction blocks are conducted using a self-designed small-scale brake dynamometer to investigate the influence of the friction block shape on the tribological and dynamical behaviours of ...

Distributed Velocity and Input Constrained Tracking Control of High-Speed Train Systems

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2021
This article investigates the velocity and input constrained tracking control problem of discrete-time high-speed train systems. A distributed cooperative tracking control algorithm is proposed for each train using the local information from its adjacent

Suspension parameters design for robust and adaptive lateral stability of high-speed train

Vehicle System Dynamics, 2022
An adequate hunting stability margin is required through the optimisation and matching of bogie suspension parameters for high-speed trains. Moreover, the dynamics design is particularly important for the robust lateral stability to adapt to wheel–rail ...

TCP Noordwijk for High-Speed Trains

2009 First International Conference on Advances in Satellite and Space Communications, 2009
In a scenario where people need to travel frequently for their business and leisure, spending a lot of time on high-speed trains, airplanes or ships, it is necessary to provide them a broadband Internet connection while moving. Broadband satellite systems, for their characteristics in terms of coverage and flexibility, can be the best solution for this

Aerodynamic effects of a high-speed train travelling through adjoining & separated tunnels

Tunnelling and Underground Space Technology, 2021
This investigation deals with numerical solution of complex aerodynamic interactions induced by a high-speed train (HST) entering and passing through tunnels with a closely adjacent gap and without in between.

An Adaptive Multisensor Fault Diagnosis Method for High-Speed Train Traction Converters

IEEE transactions on power electronics, 2021
Traction converters are safety-critical parts of traction drive systems on high-speed trains. Considering the complicated interconnections in the traction converter, it is imperative to utilize multisensors rather than single-sensor for fault diagnosis ...

Adaptive stepsize forward–backward pursuit and acoustic emission-based health state assessment of high-speed train bearings

Structural Health Monitoring
Compressed sensing (CS) is a promising tool for data compression reconstruction. However, fault diagnosis methods for high-speed train bearings based on CS and acoustic emission (AE) technologies have not been reported yet.
