【 摘 要 】

A shock tube-based calibration installation for dynamic pressure transducers was designed and manufactured. The hardware of the calibration installation contained a shock tube, two pressure transmitters, three transducers for velocity measurement, a temperature transmitter, two data sampling cards and a industrial personal computer, etc. The software of the calibration installation was a data sampling and data processing system. The functions of the software included test conditions monitoring,performance parameters computation, and calibration reports generation, etc. The performance of the calibration installation was tested. The test result showed that the range of the step pressure was 9.60 kPa–1.101 MPa, the maximum rise time of the step pressure was no more than 1μs, the minimum duration of the step pressure plateau was longer than 4 ms, the fluctuation of the step pressure plateau was better than ± 2%, and the maximum 2nd order expand uncertainty of the step pressure was less than 4%. Thus the calibration installation was qualified to be a shock tube-based dynamic pressure standard because that the performance of the calibration installation was verified to meet the requirements of ‘Verification Regulation of Dynamic Pressure transducers’ and ‘Verification Regulation of Dynamic Pressure standards’.
