摘要:
提出一种基于多层缠绕光纤环的灵敏度增强方法以实现盘式光纤加速度计高灵敏度传感。通过分析单层光纤敏感盘盘片的应力应变状态,探讨光纤盘粘贴区域、弹性盘片尺寸、传感光纤类型3种因素对灵敏度的影响,采用多层光纤敏感盘对盘式光纤加速度传感器进行灵敏度增强的方案,并通过有限元软件仿真验证。采用多层光纤敏感盘制作的盘式光纤加速度计,其加速度灵敏度能够达到6 243.4 rad/g,有效地提高了盘式光纤加速度传感器的灵敏度。
Abstract:
A sensitivity enhancement method based on multilayer fiber sensing coils is proposed to achieve high sensitivity sensing of fiber optic disc accelerometer. Through analyzing the stress-strain state of the single-layer fiber sensing disc, the influence of fiber sensing coil’s paste area, elastic disc size and sensing fiber type on the acceleration sensitivity are discussed, an effective sensitivity enhancing method with the multilayer fiber sensing coils is proposed with its simulation model of finite element software. A fiber optic flexural disc accelerometer based on multilayer fiber sensing coils has been produced with a high sensitivity of 6243.4rad/g, and the results show that the sensitivity has been effectively enhanced.
