摘要
为了提高防空火箭炮的射击密集度,该文利用近似模型方法对发射间隔进行优化分析。在建立精确防空火箭炮动力学模型的基础上,根据实验设计方法,采集动力学仿真结果的样本数据点,通过样本点构建近似模型模拟发射间隔和起始扰动中间偏差之间的非线性关系,对高精度近似模型函数进行多岛遗传算法优化分析,获得变发射间隔的满意解。结果表明:近似模型仿真技术可以显著减少优化计算成本,合理变发射间隔能够有效提高射击密集度,优化结果可以应用到该型火箭炮的实际射击中。
In order to improve the firing dispersion of the anti-aircraft rocket launcher, the variable firing interval is optimized and studied using the approximate model here. On the basis of the accurate parametric dynamic model of the antiaircraft rocket launcher, the database of dynamic simulation results is obtained by applying the design of experiments （ DOE ）. It is used to build an ap- proximation function for the non-linear dynamical relationship between firing interval variables and initial disturbance variables. The multi-island genetic algorithm method is used to obtain the optimal solution of the variable firing interval for this accurate approximation function. Optimized result shows that the approximation model can reduce the computational expense, reasonable variable firing intervals can effectively improve firing dispersion, and the optimized results can be directly applied to actual firing of the antiaircraft rocket launcher.
