Wind turbine nacelles are complex machines that are designed to operate under extreme
loads and harsh environments. Extensive tests are performed throughout their development …

Wheelsets are important components of railway vehicles, and their health directly affects
running safety, operation efficiency, and passenger comfort, so it is particularly important to …

Failures of rotating mechanical components (eg, turbine, gear, wheelset) often cause
serious shocks to the mechanical system, and real-time detection of these shocks is of …

In machinery fault diagnosis, most of the entropy features used were proposed for time
series signals, while much key information of vibration signals, including fault information …

Here a comprehensive 3-D wheel-rail rolling contact finite element model was developed to
investigate the influence of wheel-rail material properties on the dynamic wheel-rail …

Railways are one of the most important means of transportation, allowing people and goods
to move quickly, environmentally beneficially, and efficiently over long distances. To ensure …

Wheel flats are amongst the most common local surface defect in railway wheels, which can
result in repetitive high wheel–rail contact forces and thus lead to rapid deterioration and …

Abnormal vibration monitoring of high-speed trains is usually performed by analysing the
vibration acceleration of specific structures to identify characteristic signals. However, due to …

The wear and rolling contact fatigue (RCF) testing approaches for wheels and rails have
been reviewed and evaluated in this study. The study points out the advantages and …

The wheel flat can cause train and rail system infrastructure damage and endanger the
running safety. To monitor the early wheel flat, it is urgent to carry out the theoretical basic …
