Embodiment 1
[0059] Step 1: Calibrate the pressure sensor, apply a force P of 0~180KN to the pressure sensor through the tensile test machine pressure fixture 0 , and record the voltage U of the force sensor 7 under different forces through the software of the tensile testing machine, the data of the force and voltage obtained are shown in Table 1, and the force-voltage curve is drawn as attached image 3As shown, according to the formula (1), the pressure-voltage relationship is obtained.
[0060] U=kF+b (1)
[0061] U——the voltage displayed by the pressure sensor, in V;
[0062] F——the force exerted by the tensile testing machine, in N;
[0063] k—coefficient, unit V / N;
[0064] b——the initial voltage displayed by the pressure sensor when the force is 0, in V.
[0065] The pressure-voltage relationship in this embodiment is: U=0.028 P0+0.0254.
