摘要

目的探究枪械击发点火过程中关键结构参数对其点火性能的影响。方法通过LSDYNA与FLUENT联合仿真,对“击针撞击—底火发火—燃气流场发展”全过程开展数值模拟研究,通过对击发点火系统开展落锤冲击试验验证仿真模型的准确性,并系统分析闭锁间隙δ与击发药面高度H对弹壳内观测点压力特性的影响规律。结果研究结果显示,不同工况下的试验与仿真压力特征参数误差均小于15%。结论闭锁间隙对压力启动时间和峰值到达时间的影响表现为正效应,药面高度对压力启动时间和峰值到达时间的影响表现为负效应,闭锁间隙的变化对压力峰值无明显影响。本研究构建的联合仿真方法可为枪械点火系统结构设计与性能评估提供有效的分析手段。

Abstract

The work aims to investigate the effect of key structural parameters on the ignition performance of firearms during firing. A co-simulation approach integrating LSDYNA and FLUENT was employed to numerically simulate the entire process of "firing pin impact—primer ignition—combustion gas flow development". The accuracy of the simulation model was validated through drop hammer impact tests on the firing ignition system. The effects of locking clearance (δ) and primer surface height (H) on the pressure characteristics at observation points inside the cartridge case were systematically analyzed. Results showed that the error between experimental and simulated pressure characteristic parameters under various working conditions was less than 15%. The locking clearance exhibits a positive effect on pressure initiation time and peak arrival time, while the primer surface height shows a negative effect. Variations in locking clearance have no significant impact on the pressure peak value. The proposed coupled simulation method provides an effective analytical tool for the structural design and performance evaluation of firearm ignition systems.
