Synchronous vibration parameters identification by tip timing measurements [PDF]
Mechanics Research Communications, 2017 Abstract The Blade Tip Timing (BTT) measurement system is a technique to measure vibration parameters of a rotating bladed disk. In particular for synchronous vibrations the BTT provides signals versus the rotation speed of the disk starting from the measurement of the time of arrival (TOA) of each blade under the tip timing probes.
