Abstract
The pre-pressure water shock tube dynamic calibration method is put forward.The quasi-δ pulse calibration theory is used to calibrate the high pressure measurement and testing system
and the dynamic character of this system is obtained by adding several static pressures on the multiband frequency pulse signal produced by the water shock tube.It is used to do all tests
data of response of three high pressure transducers are acquired
dynamic character mathematic model is established respectively
and its spectrum is analyzed
so that the frequency response of calibrated transducer is known.
