摘要
将条形药包分为起爆端、过渡区、中部和非起爆端几个部分 ,根据等效和相似律原理 ,结合条形药包冲击波压力场特性 ,对这几部分爆炸产生的冲击波的衰减特性进行了研究。对照实验结果 ,并引入修正系数 ,得到了各部分简化计算模型 ,可以推广应用到水中条形药包爆炸。本文提出的简化模型 ,可为实际工程中条形药包水中爆炸冲击波峰值超压的计算提供参考。
A linear charge is divided into a few parts such as priming end,transition section,central section and non priming end On the basis of the principles of explosion equivalence and similitude and in the light of the characteristics of shock wave pressure from a linear charge,the attenuation of shock waves from the explosion of these parts is studied Compared with test results and introduced corrected factors,simplified calculation models for the explosion of these parts in the air are obtained and can be spread to underwater explosion of linear charges The simplified models presented in this paper can be used as a reference for the calculation of peak shockwave pressure from the explosion of underwater linear charges in practical projects
