A torsional-axial vibration measurement system using the combination of fiber-optic bundle sensor and encoding disk is intorduced.The principle
system structure
the impacts of sampling time on measurement precision
as well as systematic errors are discussed.The system was installed on the real aviation equipment for simulation.The results prove the system has advantage of high precision
easy to install and strong ability of anti-interference.The system has practical value on the detection of torsional vibration and fault diagnosis on rotating machinery.
