摘要:
通过对不同铝粉质量分数的炸药爆炸场温度、压力参数的测量，研究了在密闭条件下，炸药爆炸场温度、压力的响应特征及响应规律。结果表明，在密闭条件下，含铝炸药爆炸场温度高于理想单质炸药，铝粉质量分数的增加可提高爆炸场温度及延长温度持续时间。当铝粉质量分数为40%时，爆炸温度出现最大值，其值大约在850℃左右。相比之下，含铝炸药的爆炸场压力虽远不及理想单质炸药，但当铝粉质量分数为40%时，其超压存在一个较大值。
Abstract:
The temperature and pressure parameters of explosives at different aluminum contents in blast fields were measured, and the blast performance of explosive in terms of blast temperature,pressure response characteristic and response rules in confined condition was investigated. The results show that the blast temperature of aluminized explosive is much higher than that of ideal single explosive in confined condition, and the temperature is higher and the duration is longer when increasing the aluminum content. When the proportion of Al is 40%, the blasting temperature reaches a maximum value of about 850℃. On the other hand, the pressure of aluminized explosive is obviously low compared to the ideal single explosives, however,its overpressure can attain to a higher valuein the addition of 40% Al powder.
