Simulation Analysis of Ignition Reliability of Firearm Firing-ignition Systems
摘要
Abstract
To improve the ignition reliability of firearm firing-ignition systems,the Lagrangian-Eulerian fluid-structure coupling method(ALE)was used to establish the ignition model of the firing-ignition systems,and a parametric simulation platform was built.The pressure start time was used as the ignition output performance characteristic parameter to establish the ignition reliabil-ity proxy model of the firearm firing-ignition system.The reliability of the firing-ignition systems under the influence of changes in structure and assembly parameters was simulated and studied.At the same time,based on small-caliber rifle firing-ignition sys-tem,an ignition system simulation test device was designed,and experimental research on the ignition performance and reliabil-ity of the ignition system was carried out to verify the ignition model.The results show that the error between the calculation re-sults of the firearm firing-ignition reliability analysis model and the experimental results is 0.72%,indicating that the model has good accuracy.The influence rule of the average change of each factor on the system reliability is as follows:striking pin protru-sion>locking gap>fire table head diameter>primer shell thickness>primer loading depth>firing pin head diameter.The stan-dard deviation change has little impact on system reliability.This study provides theoretical and technical guidance for the reli-ability design of firearm firing-ignition systems.关键词
