【摘要】：引入光纖光柵傳感器,并結(jié)合螺紋管壓彎扭分離測量理論,實(shí)現(xiàn)對螺紋管所受壓力、彎矩和扭矩的測量.由測量結(jié)果可知,光纖光柵傳感器測得壓力與驅(qū)動(dòng)電機(jī)上壓力傳感器測得壓力基本相符,兩者測得壓力的差值為-11.4~15.5N;光纖光柵傳感器測得彎矩與理論值基本一致,兩者之間的差值為-0.54~0.46N·m;光纖光柵傳感器測得扭矩與驅(qū)動(dòng)電機(jī)上扭矩傳感器測得扭矩基本相符,兩者測得扭矩的差值為-0.54~0.87N·m.測量結(jié)果驗(yàn)證了光纖光柵傳感器對螺紋管力學(xué)參數(shù)測量的可行性,為螺紋管的力學(xué)參數(shù)測量提供了一種新方法.
[Abstract]:In this paper, the fiber grating sensor is introduced to measure the pressure, bending moment and torque of the screw tube, which is combined with the theory of separation of compression, bending and torsion of the screw tube. According to the measured results, the measured pressure by fiber grating sensor is basically consistent with that measured by pressure sensor on drive motor, and the difference between the measured pressure and the pressure measured by the two sensors is-11.4 to 15.5N; The bending moment measured by fiber grating sensor is basically consistent with the theoretical value, and the difference between them is-0.54 ~ 0.46 N 路m; The torque measured by the fiber grating sensor is basically consistent with the torque measured by the torque sensor on the drive motor. The difference between the measured torque and the torque measured by the fiber grating sensor is-0.54 ~ 0.87N 路m. The measurement results verify the feasibility of measuring the mechanical parameters of threaded tubes by fiber grating sensors, and provide a new method for measuring mechanical parameters of threaded tubes.
