Title Research on Shockwave Pressure Sensing System’s Shock Tube Calibration Data Processing Method
Abstract
The pressure size and scope of shock wave is assessment of the main technical indexes of the ammunition weapon power, and how to accurately measure shock wave pressure, has an important significance in engineering. Since the effective bandwidth of the shock wave is relatively rich, in order to accurately measure the of data shock waves to achieve undistorted measurement, requires measuring system has a higher operating bandwidth, and has better dynamics. In this paper, a shock tube dynamic calibration test is carried out for a typical shock wave pressure sensing system, and based on the MATLAB software environment developed a shock wave measurement system dynamic calibration data.
First, this paper reviews the calibration methods of shockwave measuring system, especially the technology utilize the shock wave tube as the excitation source, and based on shock tube to carry out typical calibration tests of shock wave pressure measurement system.
Second, the shock tube calibration test data for a typical shock wave pressure measurement system was analyzed and processed. Access the transfer function, amplitude-frequency function, and phase-frequency function of typical shock wave pressure measurement system,
Last, based on the software MATLAB, the paper designs for the wave signal analysis and processing software environment processing a variety of different data intuitively and clear.
Keywords Shock pressure sensing system, Shock tube, Amplitude-frequency function，Phase-frequency function
