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 …

The present review article addresses the vibration behavior of bladed disks encountered eg
in aircraft engines as well as industrial gas and steam turbines. The utilization of the …

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 …

In this paper, the proper orthogonal decomposition (POD) method is first time apply to the
dimension reduction of dual rotor-bearing experiment rig which is similar to an aero-engine …

The rotor–stator rubbing in rotating machinery generated as a consequence of rotor
imbalance, shaft misalignment, and casing deformation is a potential threat to the machinery …

The main aim of this paper is to propose a numerical procedure for capturing the nonlinear
dynamic characteristics of a two-spool aero-engine rotor system undergoing multi-disk rub …

Inter-shaft rub-impact, ie, the rub-impact between two rotors, may occur in an aeroengine
dual-rotor system. This paper represents the first attempt to investigate the nonlinear …

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 …

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 …

Pedestal looseness and supporting stiffness nonlinearities usually occur in rotating
machines. To enhance the robustness and accurately forecast the nonlinear behaviors of …
