温压炸药爆炸场参数的试验研究与数值模拟

摘要

The blast overpressure of thermobaric explosive (TBE) was studied based on experiment and numerical simulation with AUTODYN program. The precision of numerical simulation on blast overpressue was discussed. The characteristics of TBE overpressure can be showed roundly by numerical simulation. The peak overpressure simulated by AUTODYN is smaller than the result of experiment, while the impulse ofsimulation is in agreement with that of experiment.%对温压炸药爆炸场超压进行了试验研究与数值模拟,探讨用AUTODYN软件模拟温压炸药爆炸场超压的准确性.研究表明:用AUTODYN软件进行数值模拟可以较为准确与全面地反映温压炸药爆炸场超压分布的特点;计算得到的超压与试验结果相比偏小,比冲量的计算结果与试验结果吻合较好.
