Concerning the theory of electromagnetic fields, the sensing mechanism of optical fiber curvature modal sensors by using finite element simulation and calculation is to study the optical power leaked from sensitive zone in the condition of different parameters of bending and sensitive zone. This paper provided the design and application of fiber optical sensors in structure vibration test with theoretical...
Thin structures have been applied widely in different areas of engineering. They are prone to elastic vibration when submit to external dynamic excitations or interference, which will not only lower system stability, but also threaten the people's lives .Thus, it is significant to research this topic in depth. Generally, many acceleration sensors are put on the cover of the structure to measure the...
