Rolling bearing tips are often the most susceptible to electro-mechanical system failure due
to high-speed and complex working conditions, and recent studies on diagnosing bearing …

Structural damage detection is a key part of structural health monitoring. The generalized
flexibility matrix approach is an effective method for damage detection. Compared with the …

Achieving complete data of measured mode shapes is costly during the process of structural
dynamic test. This results in a challenge for the damage detection. This paper concentrates …

An improved generalized flexibility matrix-based method using matrix partitioning technique
for structure damage identification is proposed. As an effective damage identification …

This study concerns damage detection in plate-type structures using fractal surface
singularities with noncontact laser measurement of structural dynamic responses. The fractal …

An effective method for identifying and diagnosing the concurrent fault combined by two or
more single faults is yet to be further developed because most existing approaches focus on …

为了利用倾角影响线进行损伤识别, 由结构位移计算推导了简支梁支座处倾角影响线的解析式,
提出加权倾角影响线的概念, 将加权倾角影响线曲率指标作为标识量建立损伤识别理论 …

As is well-known, fault samples are essential for the fault diagnosis and anomaly detection,
but in most cases, it is difficult to obtain them. The negative selection mechanism of immune …
