摘 要:为得到接触爆炸下聚脲(polyisocyanate-oxazodone,POZD)涂覆钢筋混凝土梁的抗爆性能,对同一尺寸的钢筋混凝土梁开展了数值模拟研究。采用HyperMesh和LS-DYNA软件建立POZD涂覆钢筋混凝土梁模型,开展了接触爆炸下POZD涂覆钢筋混凝土梁的破坏模式和毁伤效应分析。对普通钢筋混凝土梁在接触爆炸下的破坏模式进行了模拟验证试验,研究了钢筋混凝土梁结构在不同POZD涂层位置和不同装药量条件下的破坏模式和毁伤情况,并对不同POZD涂覆位置的防护效果进行了评估,最后,将接触爆炸下POZD涂覆钢筋混凝土梁划分为3个局部毁伤等级。In order to obtain the anti-blast performance of polyisocyanate-oxazodone(POZD)coated reinforced concrete beams under contact explosion,numerical simulation studies were carried out on reinforced concrete beams of the same size.Hypemesh and LS-DYNA were used to establish the model of POZD-coated reinforced concrete beams,and the failure modes and damage effects of POZD-coated reinforced concrete beams under contact explosion were analyzed.The failure mode of ordinary reinforced concrete beams under contact explosion was simulated and verified,the failure modes and damage conditions of reinforced concrete beams under different POZD coating positions and different charge amounts were studied,and the protective effects of different POZD coating positions were evaluated.
