Uncertainty handling and analysis of rotor systems have been active research areas during
the last two decades. This paper provides a state-of-the-art review on the research progress …

Damages in rotor systems have severe impact on their functionality, safety, running
durability and their industrial productivity, which usually leads to unavoidable economical …

This paper investigates the accelerating up transient vibrations of a rotor system under both
the random and uncertain-but-bounded parameters. The Polynomial Chaos Expansion …

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 provides new insights into the uncertainty quantification and reliability analysis of
a flexible rotor system undergoing rub-impact. A probabilistic nonlinear formulation is …

The non-intrusive uncertainty quantification methods and the transient dynamic balancing
method are proposed in this paper, which are combined for the first time to analyze the …

Recently, more attention has been focused on the surrogate model using deep learning
methods due to its powerful representational ability. However, it is usually challenging to …

Aeroengines are usually designed with a dual-rotor configuration for the rotating part. A dual-
rotor system has coupling characteristics introduced by an inter-shaft bearing, and the …

In this study the authors propose to take into account the nonlinear effects induced by the
presence of a transverse crack to carry out vibratory monitoring and detect transverse cracks …

Rotor unbalances failure due to various factors such as manufacturing defects, mounting
errors, and material inhomogeneity is inevitable, and will be aggravated by bearing pulse …
