采用灰色关联分析方法,从NEPE推进剂的配方组成、结构角度计算了固体推进剂撞击感度、摩擦感度及火焰感度等多项感度的灰色关联度.通过灰色关联度的对比分析,给出了各感度的主要影响因素及影响因素顺序.配方组成研究结果表明增塑比是影响高能固体推进剂摩擦感度、局部热感度的最主要因素,HMX含量是影响冲击波感度、5 s爆发点最主要的因素,固体含量是影响撞击感度、静电火花感度、火焰感度的最主要因素;结构研究结果表明铝粉粒度是影响高能固体推进剂摩擦感度、火焰感度、5 s爆发点的最主要因素;AP粒度是影响局部热感度、静电火花感度最主要的因素;HMX粒度是影响撞击感度的最主要因素.%The Grey relationship degree of NEPE solid propellant sensitivities was calculated by numerical method, including impact sensitivities, friction sensitivities, flame sensitivities and other sensitivities from composing and granularities. The results indict that plasticization ratio is the main influence factors of friction sensitiity and regional thermal sensitiity. The contants of HMX is the main influence factors of Shock sensitivity and 5 s explosion temperature, S is the main influence factors of impact sensitivity electrostatic spark sensitivity and flame sensitivity. Granularities result indict that particle size of Al is the main influence factors of friction sensitiity, 5 s explosion temperature and flame sensitivity. The particle size of AP is the main influence factors of regional thermal sensitiity and electrostatic spark sensitivity, particle size of HMX is the main influence factors of impact sensitivity.
