为了实现对非致命防暴武器发射能量的调节并控制其终点效能,解决“近处不敢打,远处打不到”的问题,提出了恒量动能非致命打击武器系统这一全新理论,在选用了两相流内弹道模型的基础上,采用四阶龙格库塔法,利用MATLAB语言仿真技术进行编程测试,对改进型18.4mm防暴枪的内弹道进行数值仿真,并将模拟结果与实验结果进行分析比对,验证了内弹道模型和仿真结果的正确性,得到了发射过程中,膛内火药燃烧及燃气流动状态的变化规律,弄清了泄气孔位置、气室容积以及泄气孔半径对弹丸初速的影响规律,为非致命防暴武器的进一步发展打下了坚实的基础.%To adjust the transmitted energy, control the end effect, and adapt the needs of antiriot arm in the different situation are very difficult problem in non-lethal strike weapon domain. According to constant kinetic energy system theory and in the base of choosing two-phase flow model of interior ballistics, the Runge-Kutta scheme and MATLAB software were used to conduct numerical simulation of amelioration 18.4mm antiriot gun interior ballistics. And by comparing the numerical analysis result with experiment result, the model of interior ballistics and numerical simulation correctness were validated, and the laws of combustion and flow of powder were obtained. The influence regularities of the variation of ventage place, the gas vessel cubage and ventage radius on muzzle velocity of projectile were achieved, which provides theoretical foundation for further researches on the non-lethal strike weapon system.
