一种光纤光栅非接触机械振动传感器的研究
Study on Non-contact Mechanical Vibration Sensor with FBG
摘要
Abstract
This paper presented a novel non-contact radial vibration displacement measurement method based on FBG sensing technology.The structure of FBG vibration sensor was designed and theoretical analysis and numerical simulation were carried out using finite element software ANSYS.The static displacement calibration and dynamic test on the experimental device indentified the linear range of the sensor.The results indicate that the sensitivity of the sensor is as 1.14μm within the linear range,the linearity reaches 0.996 and the measurement method proposed herein can be applied to mechanical system structure damage and the distributed dynamic running state monitoring.关键词
