In order to reveal the nonlinear vibration characteristics of an actual dual-rotor-aero-engine
with blade-casing rubbing, a dual-rotor-bearing-coupling misalignment system with blade …

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 …

Rotating blade is highly susceptible to cracking in harsh conditions, which seriously affects
the dynamic characteristics of the power equipment. Existing research focuses primarily on …

Many advanced aeroengines are typically designed with coaxial coupling dual-rotor
structures. As a result, the vibration responses of the rotor system are characterized by …

This paper focuses on the dynamic responses of whole aero-engine with blade-casing
rubbing. The vibration response of casing is simulated and the dynamic behaviors of casing …

In the literature of fault diagnosis for machinery, mechanical vibration signal analysis serves
one of the most important approaches. By extracting features of vibration signal, such as …
