Embodiment 1
[0033] Embodiment 1 A fiber grating motor torque real-time measurement system, such as figure 1 As shown, it mainly includes the following structures: fixed end 1, sensing shaft 2, torque test fiber grating 3, temperature compensation fiber grating 4, support pulley 5, friction wheel 6, transmission shaft 7, transmission shaft pulley 8, pressure adjustment spring 9 , belt 10, test motor 11, input shaft 12, input shaft pulley 13 and torque sensor 14.
[0034] One end of the sensing shaft 2 is fixed to the fixed end 1 , and the other end is connected to the transmission shaft 7 through the friction wheel 6 . The torque testing fiber grating 3 and the temperature compensating fiber grating 4 are fixed on the sensing axis 2 and distributed vertically to each other. The other end of transmission shaft 7 links to each other with pressure adjustment spring 9, and belt pulley 8 is installed on transmission shaft 7, and input shaft belt pulley 13 is installed on input shaft 12, and in...
Embodiment 2
[0062] Embodiment 2 A method for real-time measurement of fiber grating motor torque, the steps are as follows:
[0063] 1. Apply a known torque at one end of the input shaft 12 for calibration. The specific method is: control the test motor 11 to apply torque, obtain the actual torque value through the torque sensor 14, and compare it with the corresponding wavelength change;
[0064] Afterwards, change the applied torque value and fix it according to the above method. After each stabilization, measure the wavelength of the fiber grating after deformation, and compare it with the original wavelength, and record the average value of the difference between each group of fiber gratings. After multiple measurements, draw the relationship curve between the wavelength difference and the applied torque to obtain the corresponding relationship of the entire measurement range and complete the calibration process. The wavelength change of the fiber grating and the calibration of the ac...
