摘　　要：为了研究电磁轨道炮的射弹初速误差源以及各误差源对初速的影响,基于MATLAB建立了电磁轨道炮内弹道模型,并采用蒙特卡洛法(Monte-Carlo)对电磁轨道炮的膛内运动过程进行了随机模拟,结果表明放电电压和电容量对初速的影响最大。进而结合仿真结果进行合理的误差分配,达到控制初速精度的目的。In order to study the initial velocity error source of the electromagnetic rail gun and the influence of each error source on the initial velocity, the interior trajectory model of the electromagnetic rail gun is established based on MATLAB. The Monte Carlo method is used to simulate the in-chamber motion of the electromagnetic rail gun. The results show that the discharge voltage and capacitance have the greatest influence on the initial velocity. Then the simulation results are combined with the reason-able error allocation to achieve the purpose of controlling the initial velocity accuracy.
