摘　　要：采用隔板试验方法对发射药冲击波感度进行了系统试验,其中包括单基、双基、三基和叠氮硝胺等不同结构的发射药,以及球形、6/7和17/19的不同药型的发射药。通过冲击波感度的试验,研究了发射药冲击波感度的响应特性,得到了发射药冲击波感度的影响因素和响应规律,主要表现为,添加黑索今(RDX)、硝化甘油(NG)、叠氮硝胺(DA)等高能组分后,发射药冲击波感度增加;随着高能组分含量的增加,其冲击波感度也增加。不同的含能组分对冲击波的影响程度不同。发射药药型尺寸变大,其装填密度降低,会显著降低发射药的冲击波感度,装填密度增加10%,冲击波感度隔板值大约增加1倍。提出了发射药组份对冲击波感度贡献的定量计算的概念,可以进行发射药冲击波感度的预估。The gun propellant shock wave sensitivity was investigated by the gap test,including single-base,double-base,triple-base and azide nitramine（DA） propellant with shape of globe,6/7 and 17/19.The gun shock wave response of propellant was studied.The effects of gun propellant shape the shock wave sensitivity was investigated.Results indicate that the more energy ingredients（RDX,NG,DA）,the higher the shock wave sensitivity of gun propellant is and the different kinds of energy ingredients affect the shock wave sensitivity differently.The bigger the gun propellant shape,the less the sample shock wave sensitivity is.On the base of these experiments,the concept of propellant ingredients shock wave sensitivity quantification count is putted forward,that can be used to study propellant shock wave sensitivity deep.
