摘要: 利用紅寶石脈沖激光器建立了三維動態散光光彈性爆破模型實驗系統,首次對條形藥包在一端起爆、兩端同時起爆、藥柱中點起爆等條件下的爆破模型進行了研究,得到了在同一剖面的4個時刻的動態應力條紋圖;對3種爆破模型的動應力場進行了對比分析,并就其爆破效果提出了相應的結論.

Abstract: 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.
