摘　　要：为满足新型固体推进剂对于钝感、高能、低特征信号的综合要求,对其配方进行了理论优化计算.首先根据均匀设计表生成了试验方案,以确保用较少的试验次数完成复杂的配方设计;其次用Matlab编制的软件计算出了各个试验配方的能量参数和燃烧产物组成,并通过撞击感度因子建立了配方组成与推进剂撞击感度的定量关系;最后运用偏最小二乘法对不同配方的能量参数、燃烧产物组成和撞击感度因子进行了综合优化分析,获得了钝感、高能、低特征信号3种指标最优时的推进剂配方组成.计算结果与文献报道的结果相近,说明本文的配方优化设计方法和软件是可信的.In order to meet the requirements of novel solid propellant for insensitivity,high energy and low signature,theoretical optimal formulations were calculated.Firstly,a uniform design table was used to get testing formulations,insuring a complex formulation with lesser test times.Then,energetic parameters and combustion product composition of the formulations were calculated with a Matlab software.The relationship between formulation and impact sensitivity was established with impact sensitivity factor.Finally,comprehensive optimization was carried out by using partial least squaresregression analysis for different energetic parameters,combustion product composition and impact sensitivity factors,getting a solid propellant formulation with optimal insensitivity,high energy and low signature.The calculated result is close to the data reported in literature,showing the reliability of the method and the software.
