The vibration phenomena which occur in rotary machines, such as power plants, can result
in catastrophic consequences. Any failure in any power plant section can result in extended …

For the past several decades, significant efforts have been devoted to modeling and
analysis of rolling-element bearings to aid in their design and application. This paper …

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 …

Time-frequency analysis (TFA) technique is an effective approach to capture the changing
dynamic in a nonstationary signal. However, the commonly adopted TFA techniques are …

In order to improve energy efficiency and compact structure, the dual-rotor structure, with low-
pressure rotor and high-pressure rotor, has been widely used in aero-engines. In severe …

Induction motors are critical components for most industries. Induction motor failures may
yield an unexpected interruption at the industry plant. Several conventional vibration and …

The rotor misalignment fault, which occurs only second to imbalance, easily occurs in the
practical rotating machinery system. Rotor misalignment can be further divided into coupling …

In the field of aviation and navigation, the spline joint-flexible coupling-rotor system has
been widely used. However, the installation of the spline joint and the drive shaft is easy to …

The operation of mechanical systems generates vibrations with a certain range of
frequencies. Pipes conveying fluid have multiple natural frequencies. It is difficult to avoid …

The development of monitoring systems for rotating machines is the ability to accurately
detect different faults in an incipient state. The most popular rotating machine in industry is …
