摘　　要：为提升改性双基推进剂配方的设计能力,利用智能算法实现配方燃速性能设计与优化,通过对比几类典型智能算法,包括遗传算法、差分进化算法、粒子群优化算法和鲸鱼优化算法,对含RDX的改性双基推进剂进行了燃速性能的智能化配方优化与设计。结果表明,智能优化算法相对于统计优化而言操作简单、运行快速,而差分进化算法拟合出的14个最优配方其燃速性能最好且更稳定。在相同的压强条件下,14个优化配方的燃速显著大于已做配方的实验值。最后利用差分算法与支持向量回归模型进一步耦合形成了一套适用于含RDX的改性双基推进剂燃速性能预测的智能算法软件,基于该智能算法软件可推演得到燃速性能优越的新配方。In order to improve the design ability of modified double base(MDB)propellant formulations,different intelligent algorithms were used for the formulation design and optimization of the burning rate property.By comparing several typical intelligent algorithms,including genetic algorithm(GA),differential evolution algorithm(DE),particle swarm optimization algorithm(PSO)and whale optimization algorithm(WOA),the intelligent formulation design and optimization of MDB propellants containing RDX were carried out.The results reveal that compared to the statistical optimization method,the intelligent optimization algorithm is simple to be operated and runs more quickly,while the 14 optimal formulations fitted by differential evolution algorithm have the best and more stable burning rate performance.Under the same pressures,the predicted burning rates of these 14 optimized formulations are significantly higher than the experimental values of the prepared formulations.Finally,a set of intelligent algorithm software for predicting the burning rate of modified double base propellants containing RDX is formed by coupling the difference algorithm with the support vector regression model.Based on the intelligent algorithm software,new formulations with the superior burning rate property could be deduced.
