摘　　要：研究了六硝基六氮杂异戊兹烷(CL-20)的含量和燃烧催化剂对含CL-20的改性双基(CL-20-CMDB)推进剂机械感度的影响,并将CL-20-CMDB推进剂的机械感度与含3,4-二硝基呋咱基氧化呋咱的改性双基(DNTF-CMDB)推进剂、含N-脒基脲二硝基酰胺的改性双基(FOX-12-CMDB)推进剂、几种定型的双基(DB)和含奥克托今的改性双基(HMX-CMDB)推进剂进行了比较。结果表明,CL-20-CMDB推进剂比有相似组成的DNTF-CMDB和FOX-12-CMDB推进剂的撞击感度高,比DNTF-CMDB推进剂的摩擦感度高,比FOX-12-CMDB推进剂的摩擦感度低。它比已定型的几种DB推进剂的撞击感度低(CL-20含量大于8%时)、摩擦感度高;比已定型的HMX-CMDB推进剂的撞击感度和摩擦感度都高(两种推进剂的氧化剂含量相当时)。The influence of the hexanitrohexaazaisowurtzitane （CL-20） content and combustion catalysts on the impact sensitivity and friction sensitivity of composite modified double base propellant containing CL-20 （CL-20-CMDB propellant） was investigated, and these sensitivities of CL-20-CMDB propellants were compared with those of composite modified double base propellant containing 3,4-dinitrofurazanfuroxan （DNTF-CMDB propellant）, composite modified double base propellant containing N-guanylureadlnitramide （FOX-12-CMDB propellant）, several double base （DB） propellants and composite modified double base propellants containing octogen （ HMX-CMDB propellant）. The results show that the impact sensitivity of CL- 20-CMDB propellant is greater than that of DNTF-CMDB propellant and FOX-12-CMDB propellant with similar composition and its friction sensitivity is greater than that of DNTF-CMDB propellant and less than that of FOX-12-CMDB propellant. The impact sensitivity of CL-20-CMDB propellant with over 8% CL-20 is less than that of several DB propellants whereas its friction sensitivity is greater than that of these DB propellants. The impact sensitivity and friction sensitivity of CL-20-CMDB propellant are greater than those of HMX-CMDB propellants when the content of oxidizer in the two propellants is equal.
