Test evaluation method for influence of special environmental factors on firearm firing energy

Abstract

The invention relates to a method for testing and evaluating the influence of special environmental factors on firearm firing energy, and belongs to the technical field of firearm testing. According to the method, copper column deformation testing experiments under different firing energy are carried out, the corresponding relation between the copper column deformation and the firing energy is established, the firing energy is obtained through a firing pin imprint test by replacing primer with the copper column for a specific gun, and the current situation that the firing energy of the gun cannot be quantitatively evaluated is solved; the method comprises the following steps: respectively carrying out firing pin mark test experiments on a target test gun provided with a copper cylinder in different special environments, and determining a corresponding relation between different special environment factors and copper cylinder deformation; through the above two corresponding relations, quantitative evaluation of the influence of various special environmental factors on the target test firearm firing energy is realized, and the influence of different special environmental factors on the firearm firing energy is revealed.

Description

technical field [0001] The invention relates to the technical field of firearm testing, in particular to a test evaluation method for the influence of special environmental factors on the firing energy of firearms. Background technique [0002] Firearms are affected by various factors such as design and manufacture, assembly process, and damage accumulation during use. During the use of troops, especially in various special extreme combat environments such as severe cold, islands, deserts, high temperatures, high humidity, and plateaus, often occur Various firing failures can affect the automatic shooting process in the slightest, damage the key parts of the firearm, and cause casualties in the severest case. [0003] The parts and components in the firearm system that complete the action of firing the primer and igniting the propellant are collectively referred to as the firearm firing-ignition system. Whether the firearm's firing mechanism can reliably fire the primer and...

AI Technical Summary

Problems solved by technology

The severe cold, island, desert, high temperature and other special combat environments in which firearms are in actual combat will affect the material properties, collision and friction characteristics of the firing mechanism of the firearm, which will have a non-negligible impact on the firing energy of the firearm. Increased firing failure rate and decreased overall product reliability

At present, there is a lack of methods and means to quantitatively test the firing energy of firearms in engineering, and there is even a lack of methods and means to evaluate the impact of special environmental factors on the firing energy of firearms.
