Paper Abstract

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 vibrations. Also, strain sensors have been recently used for measuring vibration. However, strain is difficult to measure in thin structures and there are also limitations when applying multi-spot distributed measurement method. Based on the theory that the vibration of practical structure can be decoupled into multiple vibration modes, a new concept of curvature modal sensors with optical fiber is proposed to measure vibration modes.
