Rub-impact between rotor and stator is a common mechanical fault for rotating machinery,
which will bring risks into the normal operation. Detecting the severity of the rub-impact fault …

Crack is one of the most common blade faults in the aero-engine blade, which may cause
serious accidents. The dynamic characteristics of cracked blades have been studied …

The shock and vibration response of a thin cylindrical shell is a complex fluid-structure
interaction (FSI) dynamic problem, which is very important to the monitoring of the shell …

Many factors like period stress or fatigue may lead to cracks in the rotating shaft which can
cause economic losses and accidental risk. Early crack faults will introduce very slight local …

This study presents a novel approach to real-time structural health monitoring employing
convolutional neural networks (CNN) to calculate a loss factor that measures energy …

Early crack faults will introduce subtle local changes in the whole rotor system, which may
bring difficulties to the fault detection process due to external disturbing factors. Meanwhile …

Fault detection is the characterization of a normal behavior of a system using a response
function or profile of interest and the identification of any deviation from such normal …

Vibratory power is defined as the rate of energy transmitted through a cross section of unit
width in a vibrating structure. It is known that the vibratory power is a function of the source …

With the expansion of urban construction, more earthen sites are continuously damaged by
environmental vibrations. The ancient city wall of Xi'an, which has a history of more than 600 …

In previous paper by the authors, the inner product vector (IPV) was proposed as a damage
detection algorithm which uses cross correlation functions between vibration responses …
