Numerical calculation of wing-bending moment with real-time strain monitoring by FBG modulation
This paper presents an application of Structural Health Monitoring System based on Fiber Bragg Grating sensors (FBGs) dedicated to wing-bending moment.A numerical calculation of bending moment is proposed to the application of real-time wing-bending moment monitoring.With the advantage of anti-electromagnetic interference, small size and light weight, Fiber Bragg grating (FBG) sensors have been applied in structural health monitoring system (SHMS).An experiment was performed in full-scale fatigue test of an aircraft, and the wings of aircraft were subjected to specific loading conditions, and the strain data was collected by FBGs demodulation.The relationship matrix K between the strain and the wing-bending moment was established.It is a new approach for the wing-bending moment real-time monitoring with the simple FBG strain collection modulation.
