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 …

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 …

This paper proposes numerical developments based on polynomial chaos (PC) expansions
to process stochastic eigenvalue problems efficiently. These developments are applied to …

Rotating machinery are present in many engineering applications. Such rotor systems often
subjected to high vibration loads that can be at the origin of noise or failure. For these …

This paper proposes a methodology to take into account uncertainties in non-symmetric
operators (matrices). It consists in randomly perturbing a non-symmetric matrix combining …

Rotating machinery produces vibrations depending upon the design of the rotor systems as
well as any faults or uncertainties in the machine that can increase the vibrations of such …

This paper focuses on extending an earlier investigation on the systematic and rational
consideration of uncertainty in reduced order models of rotordynamics systems. The current …

A proper orthogonal decomposition (POD)-based polynomial chaos expansion (PCE) is
utilized in this article for the uncertainty quantification (UQ) of an impact dynamic oscillator …

The response of a random dynamical system is totally characterized by its probability density
function (pdf). However, determining a pdf by a direct approach requires a high numerical …

To calculate the probability density function of the response of a random acoustic field, a
change-of-variable perturbation stochastic finite element method (CVPSFEM), which …
