带防弹钢板的钢纤维混凝土靶抗侵爆性能分析

Anti-penetration and Anti-explosion Performance Analysis ofSteel Fiber Reinforced Concrete Target with Bulletproof Steel Plate

为使防护工程具有更好的抗侵彻抗爆性能,对不同钢纤维混凝土靶板的抗侵彻抗爆性能进行研究。分别对侵彻后的靶板和带有普通钢板的钢纤维混凝土靶板进行静爆试验,根据靶板破坏情况、侵彻深度和防弹钢板的裂纹长度,结合应变测量,分析爆炸后靶板钢筋上的应变数据,得出最优的防护靶板参数。试验结果表明:15 mm厚的防弹钢板可提高钢纤维混凝土靶板的抗侵彻性能,450 mm厚的钢纤维混凝土靶板拥有最优的抗侵彻抗爆性能。

In order to make the protection project have better anti-penetration and anti-explosion performance,studies the anti-penetration and anti-explosion performance of different steel fiber concrete target plates.The static explosion test is carried out on the target plate after penetration and the steel fiber concrete target plate with ordinary steel plates.According to the destruction of the target plate,the penetration depth and the crack length of the bulletproof steel plate,combined with the strain measurement,the strain data on the steel bar of the target plate after the explosion is analyzed to obtain the optimal protective target plate parameters.The test results show that the 15 mm thick bulletproof steel plate can improve the penetration resistance of the steel fiber reinforced concrete target plate,and the 450 mm thick steel fiber reinforced concrete target plate has the best penetration resistance and anti-knock performance.
