为得到2024-T3铝合金平板结构在爆炸冲击载荷下的动态响应情况,针对所设计的试验模型,分别进行了不同药量、爆距下的多个工况的爆炸冲击试验。通过对试验后各个平板的宏观变形对比,得到了固支约束条件对2024-T3铝合金平板发生剪切失效产生的影响以及使得2 mm的2024-T3铝合金平板发生失效的爆距和药量范围;通过对试验后不同工况下的平板最大挠度的对比,得到了不同药量、爆距对于2024-T3铝合金板挠度的影响规律。
In order to get the dynamic response of 2024-T3 aluminum alloy plate structure under the impact load, the impact test of several working conditions with different dosage and burst distance was carried out for the designed test model. Through the macroscopic deformation comparison of each plate after the test, the influence of the constraint of shearing support on the shear failure of 2024-T3 aluminum alloy flat plate and the burst distance and dosage of 2 mm 2024-T3 aluminum alloy flat plate were obtained The influence of different dosage and detonation on the deflection of 2024-T3 aluminum alloy sheet was obtained by comparing the maximum deflection of slab under different conditions.
