Experimental investigation of dynamic impact of firearm with suppressor

Abstract

The internal ballistics processes occur in the tube during firearm firing. They cause tremendous vibratory shock forces and robust sound. The determination of these dynamic parameters is relevant in order to estimate reasonably the firearm ergonomic and noise reduction features. The objective of this study is to improve the reliability of results of measuring firearm suppressor’s dynamic parameters. The analysis of indicators stability is based on assessment of dynamic parameters and setting the correlation during experimental research.An examination of the spread of intensity of firearm with suppressor dynamic vibration and analysis of its signals upon applying the theory of covariance functions are carried out in this paper. The results of measuring the intensity of vibrations in fixed points of firearm and shooter were recorded on the time scale in a form of data arrays (matrixes). The estimates of covariance functions between the arrays of digital results in measuring the intensity of firearm vibrations and the estimates of covariance functions of single arrays were calculated upon changing the quantization interval on the time scale. Software Matlab 7 was applied in the calculation. Finally, basic conclusions are given.
