Blade tip timing (BTT) is the most effective technique for vibration monitoring of rotating
blades. The research of dynamic characteristics and forced responses of the blisk is crucial …

Synchronous vibration parameter identification is the key issue for the status monitoring and
health management of rotating blades. The traditional two-parameter plot (2PP) method is …

Abstract Blade Tip Timing (BTT) is one of the most effective technologies for blade vibration
measurement of turbomachinery. The blade vibration measurement indicates the …

Pre-swirl nozzle is an important cooling component that is located inside of aero-engine and
exposed to complex vibration excitation, and exploring its vibration characteristics and …

The conventional displacement-blade tip timing (D-BTT) measurements often rely on Once-
Per-Revolution (OPR) sensors to compute expected or theoretical time of arrival (TOA) …

Wake excitation is the main cause of synchronous vibration of large rotating machines'
blades, whose circumferential position reflects the distortion position of flow field. However …

Blisks extensively used in advanced aeroengines are vulnerable to vibration problems due
to the high sensitivity of the blisk's forced response to blade mistuning. This paper proposes …
