Development of a method for determining the wear of an artillery mount barrel under conditions of uncertain disturbances based on fuzzy logic and stochastic modeling

Abstract

The object of research is the processes of determining the wear of gun barrels and controlling the firing of artillery mounts under conditions of uncertain disturbances. This work addresses the problem of ensuring the adequacy of determining the current wear of the barrel and adaptive adjustment of the settings of the artillery mount when firing in short series from different positions. At the same time, the research considered the effect of random disturbing influences on the mount, including the failure of the projectile leading belt and the low quality of the powder charge. The research used fuzzy logic methods to calculate the current value of barrel wear based on the parameters of the ballistic wave of the shot and taking into account the total gun firing. Also, stochastic modeling methods, in particular, Markov chains, were used to simulate the processes of firing under conditions of random disturbances. A method for determining the current barrel wear based on fuzzy logic has been developed and investigated, which allows for adaptive adjustment of artillery mount settings when firing in short bursts under conditions of uncertain disturbances. To correctly determine wear, the proposed method uses three information channels, including the dominant frequency and depth of frequency modulation of the ballistic wave, as well as the total gun firing rate. The results of computational experiments were obtained, confirming the high efficiency of the developed method in comparison with other known methods. In particular, an increase in firing efficiency by 14.5% and a reduction in the time spent at firing positions by 3 min. were achieved when compared with the most effective method using measurements of the dominant frequency of the ballistic wave. The developed method can be used for diagnostics and control of modern artillery systems to increase firing efficiency and reduce the time spent at firing positions.
