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 gray relational analysis method was used to calculate the gray correlation degree of multiple sensitivities of solid propellant, such as impact sensitivity, friction sensitivity and flame sensitivity from the aspects of formulation and structure of NEPE propellant. Through the comparative analysis of the gray relational degree, the main influencing factors and the sequence of influencing factors are given. The results show that the plasticizer ratio is the most important factor affecting the friction sensitivity and local thermal sensitivity of high energy solid propellants. The HMX content is the most important factor affecting the shock wave sensitivity and the 5 second explosion point. The solid content is the impact impact sensitivity, Sensitivity and flame sensitivity. The results of structural study show that the particle size of aluminum powder is the most important factor that affects the friction sensitivity and flame sensitivity of the high-energy solid propellant at 5 s. AP particle size is the most important factor influencing the local thermal sensitivity and electrostatic spark sensitivity Of the factors; HMX granularity is the impact of impact sensitivity of the most important factor.
