Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings.
[0030] Such as figure 1 , figure 2 and image 3 Shown, concrete flow process of the present invention is:
[0031] Step A: Select two sections on one side of the rotating shaft connected to the elastic coupling 3 as the measurement section, one of which is located close to the elastic coupling as the first measuring point 1, and the other measurement section is located away from the elastic coupling. The shaft joint is used as the second measuring point 2, and strain sensors and two sets of strain gauges perpendicular to each other are arranged on each measuring section, and the directions of the two sets of strain gauges are respectively marked as and direction.
[0032] Step B: Start the motor to turn the rotating shaft at low speed, use the strain sensor to measure and record the average strain of each measuring point in several cycles under the low-speed cr...
