摘要 通过密闭爆发器试验考察了装填密度、点火强度和含水量对可燃药筒燃烧和能量释放性能的影响。结果表明,随着可燃药筒装填密度和点火强度的提高,药筒的燃烧速度加快,燃烧更为充分,且随点火强度的提高,装填密度对能量释放的影响逐渐减小;吸湿试验表明,可燃药筒的吸湿性较强,水分的存在对可燃药筒的火药力影响不大,但燃烧速度明显下降,同时燃烧结束时间大幅延长。 The effect of different charge density, different ignition pressure and different moisture on the combustion properties and energy release properties of combustible cartridge case was studied through closed-bomb test. The results show that as the charge density and the ignition pressure increase, the cartridges burning rate and the maximum pressure increase, the combustion stability is improved and energy of cartridges releases more sufficient. The effect of charge density on energy release decreases with increasing the ignition pressure. Strong hygroscopicity of combustible cartridges is verified through absorption experiment of moisture. When samples contain moisture, the burning rate and the combustion stability of low charge density decrease significantly, and the combustion duration extends, however,the influence on impetus is weak.
