Research on Fiber Bragg Grating Acoustic Emission Technology Applied in Helicopter Bearing Detection

摘要：

　　Fiber bragg grating acoustic emission technology can be applied in bearing detection against on the issue of existing nondestructive testing for helicopter structural components mostly not realizing in-situ on-line monitoring.Description of Fiber grating acoustic emission detection principle,with the strengths and weaknesses of fiber bragg grating sensor; detailed analysis of fault mechanism and frequency of helicopter bearing,and study of the resonance demodulation algorithm for signal post-processing; proposing a case of bearing on-line detection compared with other detection technologies against consistent analysis result.
