摘　　要：静态参数的随机散布是影响电磁轨道炮初速精度的重要因素。基于MATLAB建立了电磁轨道炮内弹道模型,并采用蒙特卡罗法对电磁轨道炮的内弹道过程进行了随机模拟。就静态参数的随机散布对初速的影响开展定量分析,为初速误差的预测和控制提供参考。分析结果表明:放电电压和电容量对初速的影响最为明显。当要求初速精度为1%时,指标分配结果为:电容量精度为2‰,放电电压精度为3‰,系统电感精度为1.3%,系统电阻精度为1.3%,电枢质量精度为2‰。The random deviation of static parameters is a remarkable factor in muzzle velocity precision of railgun.Full circuit model of the electromagnetic railgun system was built based on MATLAB with the Monte-Carlo sampling method used to simulate the launching process of railgun in bore.The paper analyzed the effects of static parameters on muzzle velocity quantitatively for error evaluation and control.The analytical results show that discharge voltage and capacitance have the most obvious effect on muzzle velocity.When the precision of muzzle velocity is defined as 1%,reasonable distribution of indices is proposed as:capacitance precision being 2‰,discharge voltage precision being 3‰,system resistance precision being 1.3%,system inductance precision being 1.3%,and mass of armature precision being 2‰.
