电动源发射过程弹丸运动状态分析研究

Analysis of Projectile Motion State during Firing Process of the Electric Power Launching System

提出了一种电动源发射系统的工作原理,基于赫兹接触理论,建立了发射过程中弹丸运动的数理模型。基于该模型进行了数值仿真研究,得到了发射过程中弹丸运动参数的变化规律以及弹丸单边过盈量对弹丸初速的影响规律。研究结果对电动源发射武器的研制具有理论指导意义。

The working principle of an electric power launching system was proposed.Based on the theories of Hertz contact,the mathematical and physical model of the projectile motion in the process of launching was established.By the aid of the MATLAB,the numerical simulation study was conducted. Based on this,the changing rules of the motion parameters of the proj ectile and the influence rules of the unilateral interference on the initial velocity of the proj ectile were obtained.The study results have great significance to guide the research and design work of the electric power launching system.
