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 …

Blade–casing interaction/rubbing can occur under the small blade-tip clearance, which may
lead to the rubbing damage, excessive wear of the abradable coating, and efficiency loss …

Rotating blade is highly susceptible to cracking in harsh conditions, which seriously affects
the dynamic characteristics of the power equipment. Existing research focuses primarily on …

This study aims at revealing the coupling vibration mechanism of RSDB system. First, a
comprehensive coupling dynamic model of RSDB system including the shaft bending, shaft …

Abstract Blade Tip Timing (BTT) method is increasingly implemented for rotating blade
health monitoring for its non-contact property. However, the BTT data is usually highly …

Dynamic strain measurement is critical in blade vibration monitoring for evaluating the
residual life and health condition of rotating blades. Blade tip time (BTT) is recognized as a …

A dynamic model of a rotor-blade system is established considering the effect of nonlinear
supports at both ends. In the proposed model, the shaft is modeled as a rotating beam …

An improved rotor-blade dynamic model is developed based on our previous works (Ma et
al. in J Sound Vib, 337: 301–320, 2015; J Sound Vib 357: 168–194, 2015). In the proposed …

Abstract Blade Tip Timing (BTT) is a widely employed non-contact measurement technique
for monitoring turbomachinery blade vibrations. The conventional BTT method typically …

The dynamic modeling and bifurcation analysis are carried out for a blade-disk rotor system
supported by rolling bearing in this paper. Considering the nonlinearity of rolling bearings …
