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 …

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 …

Turbine bladed disks or blisks, which constitute critical components of most modern
turbomachinery, are known for their complex vibratory behavior. The nonlinear dynamics …

A non-intrusive interval precise integration method (IPIM) is proposed in this paper to
analyze the transient unbalance response of uncertain rotor systems. The transfer matrix …

The non-intrusive Chebyshev surrogate coupled with the harmonic balance method is
developed to calculate harmonics and super-harmonic responses of an uncertain notched …

Abstract Uncertain‑but‑bounded (UBB) parameters are used to describe the non-
probabilistic uncertainties in rotor systems. A general non-intrusive polynomial surrogate is …

In order to investigate the natural vibration characteristics of ship propulsion shafting under
uncertainties, the random matrixes of mass, damping, and stiffness are constructed based …

This paper focuses on the vibration behaviors of a hollow-shaft rotor system in presence of
an open crack under inherent model uncertainties. Non-probabilistic interval variables are …

Parametric uncertainties are present in complex mechanical systems due to various reasons
such as material dispersion and wear. This paper investigates the effects of interval …

Rotor system is an important part in rotating machineries. As a matter of fact, rotors are
subject to uncertainties inevitably due to occasions such as assembling errors, material …
