Paper Abstract

Based on vibration measuring principle of blade tip-timing, fiber bundle sensor used as blade tip-timing is designed. "5+2" scheme of double-rate sampling is adopt to solve the under-sampled problem of asynchronous blade vibration. By using frequency identification, blade's real vibration information can be obtained. The method is applied on a model of aerial equipment to do simulation experiment whose result is similar to theoretical model, and the frequency measured is in accord with the result of strain gauge in general. Validity of measuring scheme is verified through the contrast result which also declares high practicable value of this identifying technique.
