This paper reviews recent advances in sensor technologies for non-destructive testing
(NDT) and structural health monitoring (SHM) of civil structures. The article is motivated by …

A complete surveillance strategy for wind turbines requires both the condition monitoring
(CM) of their mechanical components and the structural health monitoring (SHM) of their …

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

Deep learning methods have become popular among researchers in the field of fault
detection. However, their performance depends on the availability of big datasets. To …

From a kinematic point of view, rolling elements should continuously roll on the raceways of
rolling element bearings. When the dynamic behaviour is also considered, pure rolling …

Maintenance of wind turbines is recognized as one of the most important issues in wind
energy sector. Bearing cracks are a dominant cause of wind-turbine gearbox failures, and …

Critical mechanical faults in wind turbine systems lead to considerable downtime and repair
costs. Improving the detection and diagnosis of such faults thus brings about significant cost …

The order tracking method based on time-frequency representation is regarded as an
effective tool for fault detection of bearings with varying rotating speeds. In the traditional …

As an renewable and clean energy of the world, wind energy has gained more and more
attention and its fault diagnosis becomes more and more important. The gearbox, as the …

Wind turbines usually operate under nonstationary conditions, such as wide-range speed
fluctuation and time-varying load. Its critical component, the planetary gearbox, is prone to …
