摘　　要：针对钢管封装的大应变光纤光栅布拉格传感器的标定问题,设计了大应变试验加载平台,通过光纤光栅布拉格传感器对试验平台标定,确定了平台载荷与应变的比例系数K,按照等比加载实现了对光纤光栅布拉格传感器大于5000με的大应变标定。A large strain experimental loading platform was designed to solve the calibration problem of large strain FBG sensor encapsulated with steel tube.The proportional coefficient K between platform loading and strain was determined through calibration of experimental platform equaling with the FBG sensor.According to geometric proportion loading,the calibration of large strain FBG sensor larger then 5000 με was realized.
