| Abstract | In order to measure the chamber pressure of small caliber artilleries, a miniature internal electronic pressure gauge is designed, which adopted low power technology and miniaturization technology and storage testing technology. The working principle and the hardware design process of the gauge are described. The gauge is an intelligent pressure sensor system. The gauge is powered by battery, low power consumption, easy handling, high precision, high accuracy, and high reliability and can be reused. The gauge is used to test weapon chamber pressure which caliber greater than 57mm Dynamic calibration method based on the testing environment is proposed, the chamber pressure generator is developed; it can simulate the environments of artillery firing. Dynamic calibration system is established, the whole structure and working principle of the system is introduced. The necessity of environmental factors calibration is analyzed. The test data show that the static sensitivity coefficients and dynamic sensitivity coefficients are different. The data of the pressure gauge that have been calibrated have better stability and high confidence level. Accurate and reliable test data provides the important basis for assessing artillery, charge structure and ballistic performance. |
