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

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 ...

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

IEEE Transactions on Systems, Man & 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

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.

Brake squeal of a high-speed train for different friction block configurations

, 2021
In this work, the effect of friction block configuration on the brake squeal of a high-speed train is investigated. Three friction block configurations of simplified brake pads are used in the brake tests.

Noisiness of high speed trains

Journal of Sound and Vibration, 1977
The noise signatures of three types of French trains (Aerotrain I 80, fast train (Rhodanien) and turbotrain) were presented in the laboratory to 24 persons who gave annoyance scores to each of them. The aim of this study was to compare the resulting comfort indices with some acoustic characteristics.

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 ...
