Based on the separation measurement theory of axial force,bending moment and torque in threaded pipe,the axial force,bending moment and torque of threaded pipe were measured by using Fiber Bragg Grating sensors.From the measured results,the axial force measured by fiber Bragg grating sensors is agreement with that by pressure sensor from driving motor,the error value is between -11.4 N and 15.5 N; the bending moment measured by Fiber Bragg Grating sensor is agreement with the theoretical value,the error value is between -0.54 N·m and 0.46 N·m; the torque measured by Fiber Bragg Grating sensor is agreement with that by torque sensor from driving motor,the error value is between -0.54 N·m and 0.87 N·m.The measured results verify the validity of measuring mechanical parameters for threaded pipe by Fiber Bragg Grating sensor. This technology provides a new method of mechanical parameters measurement for threaded pipe.
