A survey on countermeasures of railway vehicle stability decrease caused by the evolution of hollow-worn wheels

Journal of Vibration and Control
With the problem that the lateral vibration acceleration of the frame of a certain type of Electric Multiple Units (EMU) gradually approaches the limit value as the running mileage increases, the tracking test was conducted on the whole vehicle’s wheel ...

Research on the mechanism of wheelset flutter in rail vehicles

Journal of Vibration and Control
To optimize the vibration phenomenon of rail vehicles, this paper refers to the “flutter theory” used in dynamic research of aircraft, bridges, and other fields to analyze vibration. This article first conducted eigenvalue correlation research on a two-

Research on the Experimental Control of Abnormal Vibration on High-Speed Lines

Transportation Research Record
With the continuous increase of operational mileage of high-speed trains in China, wheel–rail wear and various dynamics problems are gradually being exposed. Abnormal vibration in the carbody appeared during operation.

Analysis of carbody abnormal low-frequency vibration in high-speed EMU caused by thin-flange wheel profile

Journal of Vibration and Control
Carbody Abnormal Low-Frequency Lateral Vibration (CALFLV) represents a critical operational challenge for high-speed EMUs. This phenomenon was recently observed in a high-speed EMU when negotiating 2200 m-radius curves at approximately 180 km/h on a ...

Characterization of rail wear and wheel-rail contact compatibility in China’s high-speed railway network

Proceedings of the Institution of mechanical engineers. Part F, journal of rail and rapid transit
China’s high-speed railway (HSR) network, the largest globally in terms of operational mileage, faces significant challenges in maintaining rail quality and wheel-rail contact compatibility due to the demanding requirements for high operating speeds ...
