Paper Abstract
The quasi-static method with application of half-sine pressure pulse is presented to calibrate the piezoelectric
sensor, which is used for the dynamic pressure measurement of weapons. A pressure generator based on the drop
hammer hydraulic system is manufactured to get the half-sine pressure pulse. The oil cylinder of the generator is
reconstructed to install four standard pressure sensors and two calibrated sensors simultaneously. With pressure taken
from four standard sensors as calibrating excitation, and response data obtained from calibrated sensors, the working
sensitivities of sensors are worked out through regression analysis. The experimental results obtained with sensor 6215 at
the national shooting range shows that it is effective to calibrate piezoelectric sensors using half-sine pressure pulse. The
residual standard deviation of the equation fitting is less than 0.7%; the linearity is less than 0.21%; and the relative
uncertainty of the four standard sensors is less than 0.7%, under the precision target of the calibration system acceptance.
