摘　　要：研究端羟基聚丁二烯(HTPB)推进剂的固体组分因素、燃速性能与其药浆及成品的撞击感度、摩擦感度和静电火花感度之间的关联性,对于固体推进剂的安全生产与性能优化具有重要意义。本研究基于灰色关联分析方法,计算了HTPB推进剂的固体组分因素(铝(Al)含量、高氯酸铵(AP)含量、黑索今(RDX)含量及总固体组分占总质量的比例(固含量,S))及燃速与推进剂药浆及成品不同感度之间的灰色关联度,并确定了各感度的主要影响因素。研究结果表明,AP含量是影响HTPB推进剂药浆撞击感度和静电火花感度的主要因素,而RDX含量对药浆摩擦感度的影响最为显著。在HTPB推进剂成品感度的关联性方面,Al含量是撞击感度的关键影响因素,燃速和固含量分别是HTPB推进剂成品摩擦感度和静电火花感度的主要影响因素。Understanding thecorrelations between solid propellant composition,burning rate characteristics,and safety parameters including the impact,friction,and electrostatic spark sensitivities for both HTPB(Hydroxyl⁃Terminated Polybutadiene)propellant slurry and its final cured product is crucial for optimizing both the safety profile and performance characteristics of solid composite propellants.This study systematically applies the grey relational analysis method to quantitatively evaluate the relationships between formulation parameters(aluminum content,ammonium perchlorate content,RDX proportion and the total solid loading in the overall mass)and burn rate with the safety parameters measured for both HTPB propellant slurry and its final prod⁃uct.The key influencing factors for each sensitivity parameter were identified.The results indicate that ammonium perchlorate content exhibits the strongest correlation with both impact and electrostatic spark sensitivities in HTPB propellant slurry,while RDX content displays the predominant influence on friction sensitivity.Regarding the sensitivity of the final cured product,aluminum content emerges as the dominant factor influencing impact sensitivity,whereas burning rate and solid content become the primary determinants affecting the friction and electrostatic spark sensitivity,respectively.
