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.

Non-Contact Vibration Measurements of Mistuned Coupled Blades

Volume 4: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; IGTI Scholar Award, 1997
Most of the turbomachine manufacturers are using a non-contact measurement system to measure blade vibration by two probes located in the casing radially outside a blade row. All blades of a row can be observed by this system, therefore it may be considered to be an ideal solution for measuring the vibration response of mistuned blades which have quite

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 ...

An integrated measurement method of blade tip clearance and blade vibration based on blade tip timing technology

Proceedings of Global Power & Propulsion Society
Structural parameters measurement of rotating blades is an important issue to ensure long-term safe operation of turbomachinery. Blade tip clearance (BTC) and blade tip vibration (BTV) are essential parameters of rotating blades. Typically, BTC and BTV are measured by two separate systems, which poses a challenge to the available space for the sensors.
