【摘要】 为了研究某TATB基高聚物粘剂炸药在高温下的爆轰适应性,对该高聚物粘剂炸药在高温下的冲击波感度、爆速、爆压及做功能力等爆轰性能进行了测试,并采用数值模拟技术对该高聚物粘结炸药的高温恒温时间及高温爆轰性能响应时的温度进行了数值模拟。研究结果表明,该高聚物粘结炸药在高温状态下的爆轰性能与室温状态相比,主要表现为:冲击波感度偏高、爆速偏低、比动能增大。更多还原

【Abstract】 In order to study the detonation performances of TATB based polymer bonded explosive at high temperature,the sensitivity of shock wave,detonation velocity,detonation pressure and power were tested at high temperature 75℃.And the technology of numericals simulation adopted to estimate the time that explosives stayed in constant temperature box and its temperature when reacted.The results show that except the detonation pressure hadn’t changed,the sensitivity of shock wave and specific kinetic energy increased while the detonation velocity decreased at high temperature.更多还原
