摘要： 本文针对某型导弹由两级固体火箭发动机组成的联合动力装置进行九变量寻优计算.通过采用二维抛物线插值方法及合理组织迭代的技巧,解决了庞大的目标函数计算子程序耗时太多的问题;经大量调试,协调寻优步长、罚因子、收敛精度,最后成功地完成了本文的九维寻优计算,得到了能稳定收敛的最优解.所得最优方案比原参考方案的发动机总重减轻7.03kg(约占总重的2%).
关键词: 固体火箭发动机;最佳设计
Abstract: An approach was performed to develop a mathematical model for the parametric optimization of a two-stage solid rocket united motor. The objective function is the total motor weight.This model can be used in preliminary design.The optimization technique employed in this paper is SUMT-pattern search.There are 9 independent variables in the optimization process, and finally, an optimum result for a practical engineering problem is obtained.
Key words: Solid rocket engine;Optimum design
