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 …

Gear systems operating at high speeds and under heavy loads are susceptible to
continuous multiple tooth surface spalling. The time-varying meshing stiffness (TVMS) model …

To reveal the mechanism of gear meshing induced rubbing and investigate the nonlinear
dynamic response characteristics of a gear-dual-rotor system with multi-position rubbing, a …

Despite of wide applications of damping support structures in rotor vibration reduction, their
performance is generally unsatisfactory in the high-frequency range. A new method of oil …

The aero-engine spur gear system is often designed as thin rim structure due to lightweight
consideration, which leads to traveling wave resonance phenomenon when spur gear …

There exists a lot of research on the nonlinear vibration of the pipeline system with different
boundary conditions. To the best of our knowledge, little research on the actual constraint of …

A rotating pre-twisted graphene reinforced composite panel model is developed to
investigate resonance behaviors of the rotating blade under dangerous mode. Three types …

Considering the effects of blade rotation and casing flexibility, a new blade-casing rubbing
model is proposed. The blade is assumed to be clamped on a rigid disk and simulated by …

Rotor–stator rub is a common and high-risk fault in large rotating machines. As for the aero-
engine rotor system, bolted joints are widely adopted to fasten the multiple rotating parts into …

This paper aims to gain insight into the nonlinear modal characteristics and the possible
influence of the modes on the responses for the practical dual-rotor system with rub-impact …
