炸药的爆轰性能是评价炸药综合毁伤能力的重要指标,是进行炸药装药设计、开发和优选工作的前提.为实现对炸药的综合爆轰性能进行合理评估,必须对炸药的5大爆轰参数(爆热、爆速、爆压、爆容、爆温)进行综合考虑和计算.尝试应用针对多元统计技术的主成分分析法,对TNT、RDX、HMX等常用单质炸药的所有爆轰参数开展了分析与评估.结果表明,炸药各爆轰参数的信息重叠度较大,主成分的贡献率可达到90.1％,在爆轰性能综合评估中可以只参考爆热和爆速.最后利用第一和第二主成分的贡献率为权数,构造了炸药爆轰性能综合评估函数；对常用炸药的强弱排序也与各自威力经验值相符,评估有效.%The detonation performance is not only an important indicator of the comprehensive evaluation for explosive damage ability, but also the premise for the explosive design, development and optimization work. To achieve a reasonable assessment of the explosive detonation performance, five detonation parameters, such as the heat of explosion, velocity of detonation, pressure of detonation, volume of explosion, temperature of explosion, require comprehensive consideration and calculation. Principal component analysis based on multivariate statistical techniques is attempted to apply to analyzing and evaluating detonation parameters of TNT, RDX, HMX and other ordinary explosives. The results showed that the overlap ratio of the detonation parameters is high with the contribution rate of the main ingredients to be up to 90. 1%. The explosion heat and the detonation velocity can only be referred in the comprehensive assessment of the detonation performance. Finally a comprehensive evaluation function with the contribution rate of the first and second principal components is constructed. It can be seen that the sorting of detonation performance of common explosives is consistent with their empirical power value, therefore, the assessment is valid, and worthy of promotion.
