摘要

目的研究子弹撞击下某丁羟三组元推进剂（Al/AP/HTPB）发生燃烧的弹速阈值,基于子弹撞击试验建立有限元模型,模拟并观察不同工况下推进剂燃烧的响应等级,明确此类推进剂燃烧响应阈值及规律,为安全评估提供技术支撑。方法开展针对目标推进剂的子弹撞击试验,观察不同弹速下推进剂的响应性质、测量空气超压。基于试验结果建立有限元模型,仿真模拟并观察推进剂的响应情况。结果试验结果表明,弹速超过258.2 m/s时,推进剂发生燃烧响应;弹速为191.8 m/s时,推进剂不反应。有限元模型与试验结果误差较小,仿真结果表明,弹速超过200 m/s时,推进剂发生燃烧响应,但燃烧速度缓慢。结论当弹速为191.8 m/s时,推进剂不发生反应;当弹速为200 m/s时,推进剂的燃烧速度十分缓慢;基于子弹撞击试验建立的有限元模型与试验中推进剂反应等级相同,可以为此类推进剂的现实应用和特性研究提供参考。

Abstract

The work aims to investigate the velocity threshold for combustion response of a ternary Al/AP/HTPB propellant under bullet impact and establish a finite element model based on bullet impact tests to simulate and observe the propellant's combustion response under different conditions, clarifying the combustion response thresholds and laws of such propellants and providing technical support for safety assessment. Bullet impact tests were carried out on the target propellant to observe its response characteristics at different velocities and measure air overpressure. A finite element model was established based on the test results for numerical simulation and observation of the propellant response. Test results demonstrated that combustion response occurred when the bullet velocity exceeded 258.2 m/s, but no reaction occurred at 191.8 m/s. The finite element model showed minimal discrepancies with test results, indicating that combustion initiated above 200 m/s with slow propagation rates. At 191.8 m/s, no reaction occurs, while at 200 m/s, combustion progresses slowly. The finite element model established based on bullet impact tests matches the propellant reaction level in the test, and can serve as a reference for the practical applications and characteristic studies of such propellants.
