In this paper, a multi-disciplinary analysis method is proposed for evaluating the fatigue life
of railway vehicle car body structure under random dynamic loads. Firstly, the hybrid fatigue …

This paper discusses some key problems faced in high-speed train operation. These
problems include: wheel tread concave wear causing the lateral oscillation of the train in …

The resonance vibration of flexible car-bodies greatly affects the dynamics performances of
high-speed trains. In this paper, we report a three-dimensional train–track model to capture …

Many issues of concern in the railway industry are fundamentally caused by dynamic wheel-
rail interaction. To deal with these issues, the characteristics of the interaction must be …

Hollow wear is a common type of wheel profile evolution in high-speed railway, causing
special contact characteristics in turnouts. Taking into account the flexibility of wheelsets and …

In this paper, a clustering method for KMedoids based on dynamic time warping (DTW-
KMedoids) is designed to analyze multi-channel signals, and a lightweight network …

Derailments on bridges, although not frequent, when occurs due to a complex dynamic
interaction of the train–track–bridge structural system, are very severe. Furthermore, the …

The running safety of high-speed trains has become a major concern of the current railway
research with the rapid development of high-speed railways around the world. The basic …
