Blades play a vital role in wind turbine system performances. However, they are susceptible
to damage arising from complex and irregular loading or even cause catastrophic collapse …

Pre-stressed bolted joints are widely used in civil structures and industries. The tightening
force of a bolt is crucial to the reliability of the joint connection. Loosening or over-tightening …

Vibration-based damage detection techniques receive wide attention of the research
community in recent years to overcome the limitations of conventional structural health …

Bolted connections are prone to losing their preloads with the increasing service life, thus
inducing engineering accidents and economic losses in industries. Therefore, it is important …

This article presents a novel second-order output spectrum–based method for detecting and
localizing multiple bolt loosening faults in complex structures with a sensor chain. This new …

The beam-like structures commonly exist in engineering systems and there are many critical
issues relevant to fault diagnosis of those structures. Noticeably, among all other existing …

In this paper, an adaptive trajectory tracking controller based on extended normalized radial
basis function network (ENRBFN) is proposed for 3-degree-of-freedom four rotor hover …

A novel nonlinear second-order output spectrum (SOOS) approach for feature
characterization and fault detection and location of bolt loosening in a satellite-like structure …

In the monitoring process of petrochemical equipment rotating machinery, the collected
large data easily lead to valuable data loss in the pre-processing process and affecting the …

This paper presents a novel second-order output spectrum (SOOS) based method with a
local tuning approach (LTA) for the precise localization of multiple bolt-loosening faults in …
