Vibration measurement of compressor blades with fiber Bragg grating

2018 International Conference on Electronics Technology (ICET), 2018
We reported the vibration measurement of compressor blades by using fiber Bragg gratings. The low order vibration modes were focused on and the corresponding distributions of FBGs were designed. The arrangement position of the fiber Bragg grating sensor was determined by analyzing the strain distribution of the blade model in the low order mode. It was

Turbine blade vibration measurement methods for turbocharges

2016
This paper presents and compares the most important and often used methods to measure turbine blade vibrations: use of strain gauges and telemetry system which is an intrusive method or, on the other site. The Blade Tip Timing (BTT) method known as Non-Intrusive Stress Measurement (System) NSMS.

On-Engine Measurement of Automotive Turbocharger Turbine Blade Vibration

SAE Technical Paper Series
<div class="section abstract"><div class="htmlview paragraph">Automotive turbochargers are carefully designed to avoid resonance of the turbine blades and backwall, which can result in High Cycle Fatigue failures. Blade Tip Timing is an established technique which utilizes fiber optic probes to measure turbine blade displacements in real ...

SLDV technology for measurement of mistuned bladed disc vibration

2008
Bladed discs are very sensitive structures and the amplitude vibration of each blade can vary significantly from blade to blade due to a series of factors such as geometrical inhomogeneity between blades or material properties. These factors lead to bladed disks mistuned thus the forced response amplitudes can be much higher than the level predicted ...
