The rolling bearing rotor (RBR) system is the kernel of many rotating machines, which affects
the performance of the whole machine. Over the past decades, extensive research work has …

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 …

Similitude theory is widely used to predict the structural responses of the full-size prototype
through scaled models and is categorized into complete and partial similitude according to …

Pedestal looseness and rotor-stator rub are two common faults in rotating machines. To
increase the thrust-weight ratio and enhance fuel efficiency of aero engines, the structural …

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 presents a modified incremental harmonic balance (IHB) method to analyze the
nonlinear dynamic and thermal coupling characteristics of rotor-bearing systems after …

This paper focuses on the nonlinear dynamics and thermal bidirectional coupling
characteristics of a rotor-ball bearing system. The motion equations of the rotor system are …

In this study, a new rotor–ball-bearing–casing coupling dynamic model for a practical aero-
engine is established. In the coupling system, the rotor and casing systems are modelled …

This paper proposes a new theoretical method to investigate the thermal behaviors of the
inter-shaft bearing considering the nonlinear dynamic characteristics of a dual-rotor system …

The nonlinear thermo-mechanic coupling effect refers to the interaction between the
nonlinear dynamic characteristics of a dual-rotor system and the thermal effect of an …
