摘　　要：基于光纤(Bragg)光栅传感技术的优点,提出了往复式压缩机的光纤光栅振动监测方法。设计了一种"L"型结构的FBG振动传感器,并对传感器及其系统进行了实(试)验研究。结果表明,该传感器的工作频率范围为3～60Hz,灵敏度为86pm/(m.s-2),加速度测量范围大于25m/s2,其系统具有抗电磁干扰和本质安全防爆的特点,长期稳定性好,易于实现远程、在线测量,很好地满足了往复式压缩机振动监测的需要。A new measuring method for vibration of reciprocate compressor based on fiber Bragg grating（FBG） sensing technology is brought forward for the first time. The author has schemed out FBG vibration sensor with ＂L＂design struc- ture and done some experiments to test the properties of the sensor and its system. The results show that the sensor＇s operating frequency range is 3~60 Hz, sensitivity is 86 pm/（m · s-2）, acceleration measuring range is greater than 25 m/s2 ,and its system has such advantages as EMI, intrinsic security, good long-term stability, easy to be used for re- mote and on-line monitoring. So the system is capable of meeting the demand for vibration monitoring of reciprocate com- pressor.
