摘要
利用红宝石脉冲激光器建立了三维动态散光光弹性爆破模型实验系统，首次对条形药包在一端起爆、两端同时起爆、药柱中点起爆等条件下的爆破模型进行了研究，得到了在同一剖面的４个时刻的动态应力条纹图；对３种爆破模型的动应力场进行了对比分析，并就其爆破效果提出了相应的结论．
An experimental system of blast model of three-dimension dynamic astigmatic photo-elasticity is established by using the ruby pulse laser apparatus. By detonated the column and trip-shaped charge at one side, two sidesor or in the mid-point, four dynamic stress fringe patterns of the same section at four different second are got, then the dynamic stress field of three kind of blast model is constrasted and analyzed. Finally the corresponding conclusions of blast effect are got.
