摘　　要：为了研究温压装药的装填比对战斗部毁伤威力的影响,开展了以65%的奥克托今和35%的高活性级配铝粉为主要组份30 g温压装药爆炸后生成产物及输出能量特性的试验研究。依据试验结果,建立了表征温压战斗部毁伤威力的总能量和总比冲量的数学模型。借助一枚装填70 kg温压炸药的200 kg战斗部距地面1.5 m处的静爆试验的结果,利用数学模型计算了该温压战斗部起爆后距爆心不同距离处的冲击波超压和比冲量。结果表明,计算结果与静爆试验测量结果符合较好,验证了所建数学模型的正确性。应用该模型计算了200 kg温压战斗部爆炸后距爆心不同距离处的总比冲量随装填比的变化情况。表明装填比为40%左右时,有最大的总比冲量和毁伤威力。To study the effect of loading ratio of thermobaric charge on the damage power of warhead, the experimental study on formation products and energy output characteristics after explosion of 30 kg thermobaric charge composed of 65% HMX and 35% high activity grading AI powder as main components was carried out. According to test results, the mathematical calculation model of characterizing the total energy and total specific impulse of thermobaric warhead damage power was set up, With the help of results obtained by static explosive test from the ground 1.5 m of a 200 kg thermobaric warhead with 70 kg thermobaric charge, the overpressure and specific impulse of shock wave at different distance to the explosion center were calculated using the obtained mathematical model. Results show that the calculated and the experimental results have good consistency, which proves correct- ness of the mathematical model. The changes in total specific impulse at different distance to the explosion center for the 200 kg thermobaric warhead with different loading ratio were calculated, indicating that the specific total impulse and damage power has a maximum value when the Ioading ratio is 40%.
