| Abstract: |
| A large strain experimental loading platform was designed to solve the calibration problem of large strain FBG sensor encapsulated with steel tube. The proportional coefficientKbetween 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 then5000μεwas realized. |
