恒能打击非致命武器内弹道仿真研究

Simulation of Constant Kinetic Energy Striking of Non-Lethal Weapons Interior Ballistics

结合变初速射击和定效非致命杀伤的恒能打击理论,在选用准两相流内弹道模型的基础上,运用四阶精度的Runge-Kutta算法和二阶精度的Lax-Wendroff差分法处理内弹道模型,在MATLAB环境下对模型进行仿真,分析发射过程中泄气孔、泄气室和气室孔的参数改变对弹丸初速的影响规律,得到恒能打击效果较为理想的一组参数值,并与实验结果进行比对,验证模型的准确性,为恒能打击非致命武器的进一步发展提供依据.

Based on the quasi two-phase flow of the interior ballistic model as well as the theories of variable velocity shooting and constant kinetic energy non-lethal antipersonnel strike, this paper applies the Runge-Kutta and Lax-Wendroff to handle the interior ballistic model. In the MATLAB environment, analysis is carried out on the law of initial velocity which is influenced by the parameter changes of the frustrated chamber hole, frustrated chamber as well as gas chamber hole. A satisfactory set of parameters is obtained on the constant kinetic energy strike effect. Compared to the result of the simulation, the accuracy of the model is verified and a basis for further development of using non-lethal weapons with the constant energy is provided.
