摘　　要：为了研究HMX基和TATB基高聚物粘结炸药(PBX)爆轰波的拐角性能,采用蘑菇(Mushroom)试验测试了HMX基炸药(含95%HMX的PBX-Ⅰ,含85%HMX和7%TATB的PBX-Ⅱ)和TATB基炸药(含95%TATB的PBX-Ⅲ)在起爆直径7mm和10mm条件下的出射角、熄爆角及延迟时间。结果表明,在起爆直径7mm的情况下,PBX-Ⅰ的出射角(75.5°)略大于PBX-Ⅱ的出射角(74.4°),PBX-Ⅰ和PBX-Ⅱ的熄爆角均为90°,都能够发展为类似球形,显示HMX基PBX均有较好的拐角性能。在起爆直径10mm的情况下,PBX-Ⅱ的出射角为78.6°,熄爆角为90°,PBX-Ⅲ的出射角为16.1°,熄爆角为60.4°。对于HMX基PBX,随着起爆直径的增大,出射角增大。在HMX基PBX中加入TATB,出射角减小。当HMX全部用TATB代替,出射角显著减小,三种炸药的拐角性能优劣顺序为:PBX-Ⅰ>PBX-Ⅱ>PBX-Ⅲ。To study the corner performance of detonation waves for HMX-based and TATB-based polymer bonded explosive（PBX）,the breakout angles,failure angles and delay time for PBX-Ⅰ containing 95%HMX,PBX-Ⅱ containing 85%HMX and 7%TATB,and PBX-Ⅲ containing 95%TATB with initiating diameter of 7 mm and 10 mm were studied by Mushroom test.Results show that with initiating diameter of 7 mm,the breakout angle of PBX-Ⅰ（75.5°）is slightly greater than that of PBX-Ⅱ（74.4°）,and the failure angles of PBX-Ⅰand PBX-Ⅱare 90°,and they are able to develop for similar spherical.It reveals that HMX-based PBX explosive has better corner performance.With initiating diameter of 10 mm,the breakout angles and failure angles are 78.6°and 90°for PBX-Ⅱand16.1°and 60.4°for PBX-Ⅲ,respectively.The breakout angles for HMX-based PBX increase with increasing the initiating diameter,and decreases when TATB is added in HMX-based explosive.The breakout angle decreases significantly as substituting all of HMX with TATB.The corner performance of detonation waves for the three kinds of explosive decreases in the order：PBX-ⅠPBX-ⅡPBX-Ⅲ.
