![]() The traditional position charge amplifier is placed on it, the signal is not easy to be interfered, and all high interference circuits are sealed, so that the signal can be transmitted for a long distance without affecting the signal quality, which is convenient to use. ![]() With the development of IC, a new sensor has been developed. The shortcomings of piezoelectric sensors are as follows: high output obstacles lead to increase of rise time low tuning frequency makes it impossible to achieve a good negative pressure curve signal conversion and processing are more complex, requiring high insulation of cables and joints electromagnetic waves generated in explosion environment are connected and debris and vibration of mounting bracket can easily cause signal deviation and affect test results. Even if the light film is attached to the back of the polished silicon chip to reduce light transmission, the strong light generated by the explosion can cause system failure and reduce the reliability of the system. The biggest disadvantage of piezoresistive sensor is that its silicon element is very sensitive to the light produced by explosion. At present, there are two kinds of shock wave sensors at home and abroad: piezoresistive sensor and piezoelectric sensor. ![]() The research on the overpressure and impulse of shock wave can provide an important reference for the comparison of the impact damage strength of weapon equipment. The shock wave storage test system is optimized when the parameters of the digital voltage circuit sensor are variable. Finally, experiments are carried out in different environments to verify the reliability, survivability, and flexibility. The influence of disk is 10% higher than that of pen, and the change rate of relative difference is increased by 1.5% with the increase of concave-convex value. The results show that, under the same inlet pressure, the larger the bulge or depression value, the greater the influence on the experimental results. Based on fluid dynamics simulation theory and numerical simulation method, the normal and concave-convex three-dimensional models of two pressure measuring devices are constructed by using the flow waveform of calculator, and then, the network is divided. This paper mainly studies the design of shock wave storage test system with variable parameters based on numerical piezoelectric circuit sensor. Shock wave data storage has the characteristics of large scale, complex structure, low cost efficiency, and strong timeliness. With the wide application of science and technology in the field of weapons, shock wave is an important breakthrough point in weapon research, and the storage and testing system of shock wave is a breakthrough point that people pay most attention to at present.
