为了研究含Mg基储氢材料、含Ti基储氢材料、含ZrH2储氢材料等三种混合炸药的能量输出特性，采用恒温式爆热量热仪和水下爆炸系统分别研究了3种含储氢材料混合炸药的爆热和水下能量特征。结果表明：在RDX/储氢材料/AP/others温压配方体系中，3种含储氢材料炸药爆热的关系为含Mg基＞含Ti基≫含ZrH2，爆热值分别为7587.0606，6416.4741，3950.6279 kJ·kg-1，表明含储氢材料炸药的爆热与储氢材料的化学潜能呈正相关。水下爆炸中，含储氢材料混合炸药的冲击波峰值压力、冲量、能流密度、冲击波能的大小关系保持一致，从大到小依次为含Mg基、含Ti基、含ZrH2储氢材料混合炸药，冲击波能依次分别为1.41倍、1.26倍、0.97倍TNT当量，表明活性高、潜能大的储氢材料对水下爆炸冲击波的推动作用更大。储氢材料在水下爆炸能量中主要贡献在气泡脉动上，含Mg基、含Ti基、含ZrH2储氢材料混合炸药的气泡能分别为2.17倍、1.78倍、0.86倍TNT当量，表明Mg基储氢材料在二次反应能量释放程度上最优，其次是Ti基储氢材料，ZrH2的反应程度最低。3种含储氢材料混合炸药的水下爆炸能量和爆热的大小趋势保持一致，总体能量水平依次是含Mg基＞含Ti基≫含ZrH2。含Mg储氢材料炸药的水下爆炸能量最大，达到2.02倍TNT当量。ZrH2在温压体系配方中的适用性不强，爆热和水下爆炸能量均低于TNT。“,”In order to study the energy output characteristics of three composite explosives containing Mg‑based hydrogen storage materials， Ti‑based hydrogen storage materials and ZrH2 hydrogen storage materials respectively， a constant temperature detonation heat calorimeter and an underwater explosion system were used to study the detonation heat and underwater energy characteristics of the explosives. The results illustrated an order of the detonation heat in terms of a thermobaric formulation of RDX/hydrogen storage material/AP/others， which was Mg‑based sample>Ti‑based sample≫ZrH2‑based sample. Accordingly， the detonation heat for the three explosives were 7587.0606 kJ·kg-1， 6416.4741 kJ·kg-1 and 3950.6279 kJ·kg-1. It was indicated that the detonation heat of the explosives containing hydrogen storage materials was positively correlated with the chemical potential of each hydrogen storage material. In underwater explosions， the explosion parameters including peak pressure， impulse， energy flow density and shock wave energy of the composite explosives presented a similar order， that the Mg‑based sample was the best and the ZrH2‑based sample was the worst. Accordingly， the shock wave energy was 1.41 times， 1.26 times and 0.97 times of TNT equivalent for each formula. It was showed that hydrogen storage materials with much higher activity and potential energy could be beneficial for the shock wave in underwater explosion. The contribution to the energy released in underwater explosion of hydrogen storage materials was mainly in the form of bubble pulsation. The bubble energy of the composite explosives containing Mg‑based， Ti‑based and ZrH2 hydrogen storage materials were 2.17 times， 1.78 times， and 0.86 times of TNT equivalent respectively， indicating that Mg‑based hydrogen storage material had the best energy releasing performance in the secondary reaction， followed by Ti‑based hydrogen storage material and ZrH2was the worst The trends of the explosion parameters of the composite explosives in detonation heat test and underwater explosion test were consistent. The overall energy level of the explosives was in the order of Mg‑based sample>Ti‑based sample>ZrH2‑based sample. The explosive containing Mg‑based hydrogen storage material had the largest energy in underwater explosion， reaching up to 2.02 times of TNT equivalent. The applicability of the ZrH2 in thermobaric formulation was not strong for both of the energy tested in detonation heat and underwater explosion was lower than TNT.
