摘　　要：为满足某导弹弹射用燃气发生器的弹射出筒速度及低冲击要求,设计了一种导弹弹射用燃气发生器,对其作用过程进行分析和数学建模,采用Matlab软件对燃气发生器高压室/低压室及导弹运动过程进行数值仿真求解,并将仿真数据与试验数据进行对比。结果表明该仿真模型建立及仿真参数设计合理,能较准确地预示该类型弹射燃气发生器作用过程及导弹运动各项参数。In order to meet the ejection barrel speed and low shock requirements of gas generator for projectile ejection,a gas generator was designed,its action process was analyzed and mathematically modeled,and the Matlab software was used for simulated calculation of high/low pressure chamber and projectile motion.Comparing the simulation data and test data,it is found that the simulation model establishment and the simulation parameters are designed reasonably,which can more accurately predict the action process of the gas generator and motion parameters of the projectile body.
