Analysis of the influence of track irregularity on high-speed train ride comfort
Vehicle System Dynamics, 2023 The vibration of high-speed trains induced by track irregularities is a main factor affecting ride comfort. Especially, the long-wavelength track irregularities can reduce the passengers’ ride comfort by increasing the vibration of the high-speed trains.

Using High-speed Train Induced Signal to Estimate High-Speed Train Acceleration
Journal of Physics: Conference Series, 2023 Abstract A moving high-speed train (HST) stimulates various seismic waves near a high-speed railroad (HSR). Thus, the HST has been treated as a combined and moving seismic source. Moreover, the speed and acceleration of HST are typical moving parameters for this HST seismic source. Certain devices, such as GPS, Doppler radar, and cameras,

Mechanism of high-speed train carbody shaking due to degradation of wheel-rail contact geometry
International Journal of Rail transportation, 2022 The carbody shaking phenomenon (CSP) can greatly reduce the ride comfort of high-speed trains. To investigate the abnormal vibration feature and causes of the CSP, extensive field measurements and numerical simulations were conducted. A three-dimensional

Seamless LTE connectivity in high‐speed trains [PDF]
Wireless Communications and Mobile Computing, 2015 AbstractHigh‐speed train (HST) is revitalizing the train as a preferred mid‐range transportation system. The provision of broadband Internet connectivity onboard trains is one of the key challenges in the competition among train operators. Unprecedented spectral efficiency and data rates (up to 100Mbps in high mobility) of the Universal Mobile ...
