摘要:
为研究导气式枪械射击精度,提出了射击精度仿真分析方案,在分析内弹道随机变量的基础上,建立内弹道方程并计算得到弹丸初速及其误差量; 通过仿真获取弹丸出枪口时的枪口跳动量及其误差量,同时考虑弹形系数及其误差量,建立随机外弹道方程,获得100 m射程处的立靶散布情况。经试验验证,枪口跳动量,立靶散布R50、R100的仿真计算结果与试验结果基本一致,误差小于15%。该方法可用于分析步枪的单发射击精度,在一定程度上能够支撑和指导枪械设计。
Abstract:
To study the shooting accuracy of air-guided rifle,the simulation analysis method was proposed. The internal ballistic random variables were analyzed. On this basis,the internal ballistic equation was established,and the initial velocity and error of the bullet were calculated. The muzzle bounce value and error were obtained based on the simulation while the bullet coming out of the muzzle. Considering the shape coefficient and error,the above parameters were input into the random external ballistic equations,and the vertical target dispersion at 100 m range was finally obtained. The simulation results of muzzle bounce value,vertical target dispersion R50 and R100 are basically consistent with the test results,and the error is less than 15%. This method can be used to analyze the single shooting accuracy of firearms,and it can support and guide the design of firearms.
