In large rotating machines, the rotor system involves multistage disks, where bolted joints
are the basic form to connect the adjacent disks. Those bolted joints, subjected 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 …

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 …

Nonlinear elements found in fluid film journal bearings and their surrounding structures are
known to induce sub-and super-synchronous, chaos and thermally induced instability …

This study aims to investigate the nonlinear vibration properties of a rotor-bearing system
carrying a multi-disk bolted joint with a fixed-point rubbing fault. For this purpose, a …

Modern industrial requirements are continuously demanding better performances and
higher rotational speeds from current aero-engines. Under this circumstance, mitigation of …

Wear usually occurs in the loaded part of hydrodynamic bearings and leads to bearing
geometry imperfections. This paper investigates the effects of wear-induced geometric …

Rubbing between rotor and stator may cause structural damage and lead to serious
accidents. Diagnosing early-stage faults and determining the severity of rub-impact is of …

This research article investigated the rotor-casing contact phenomena of a high-speed rotor-
bearing system under mass unbalance situation. Here, large deflection rotor-bearing model …

In order to enhance the stability of the turbocharger rotor system, the nonlinear dynamic
