Overpressure Comparison of Blasting in Air and Special-Made Hemispherical Structure

  • 摘要: 爆炸焊接过程会产生爆炸地震、冲击波、有毒气体和噪音等有害效应。设计并制作一个直径为36 m、入口和排烟口直径分别为8 m的半球形结构,用以降低爆炸焊接过程中产生的超压影响。为了研究实际超压降低效果,进行了裸爆和按1/6比例建立的半球形结构内爆炸的超压对比实验。实验结果表明:当超压的传播距离大于20 m时,这种半球形结构能有效降低爆炸焊接过程中产生的超压;对于相同的超压传播距离,切线方向(垂直于半球形结构入口方向)比径向方向(半球形结构入口方向)的超压降低效果好。结合冲击波的传播和反射特点,对超压降低的可能原因进行了分析。
