Contact behaviour and vibrational response of a high-speed train brake friction block

Tribology International, 2020
Brake experiments were conducted on a typical kind of friction blocks of a high-speed train. The friction and wear, interfacial temperature, vibration, and noise generated at or by the brake interface were investigated, and the interrelationship between ...

Stability of high speed trains

Physics in Technology, 1973
Recent developments in the understanding of the lateral dynamics of railway vehicles are reviewed with particular reference to the problems of dynamic stability, guidance and response to track features. The emphasis is placed on the physical models used and the broad conclusions they lead to, rather than the engineering design that represents the ...

Fault Diagnosis of High-Speed Train Bogie Based on Capsule Network

IEEE Transactions on Instrumentation and Measurement, 2020
Intelligent fault diagnosis of bogie is fundamental for the reliability, stability, and security of a high-speed train (HST). However, thorny issues, including complicated structure of bogie and complex motion states of HST, aggravate the difficulty of ...

Multiple Convolutional Recurrent Neural Networks for Fault Identification and Performance Degradation Evaluation of High-Speed Train Bogie

IEEE Transactions on Neural Networks and Learning Systems, 2020
As an important part of high-speed train (HST), the mechanical performance of bogies imposes a direct impact on the safety and reliability of HST. It is a fact that, regardless of the potential mechanical performance degradation status, most existing ...

The braking behaviors of Cu-Based powder metallurgy brake pads mated with C/C–SiC disk for high-speed train

, 2020
The improvement of braking systems for the high-speed train is driven by the demand for high & stable coefficient of friction (COF) as well as low wear at high speed. Given to the fading COF and severe wear of powder metallurgy (P/M) pad mated steel disk

High-power High-speed Road Train System

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">This paper presents the design and development of a high-power, high-speed “road train” (with both on- and off-road applications). The system looks to optimize both high-speed operation and low-speed, close-quarters driving with the introduction of autonomous power modules. Each trailer in the road train has it own
