| 摘 要： | 采用ANSYS/LS-DYNA软件对复合结构各层中的爆破能量的分布进行了系统的数值模拟研究；由计算得到的复合防护结构中能量的分布规律显示，泡沫混凝土的反射、吸能作用非常明显，改变了防护结构内的能量分布状态，各层的能量分布发生了很大的改变，能量的分布向上转移，其最下层能量仅为无吸能层结构的14％。

| Abstract: | The anti-blasting and absorbing energy mechanisms of composite protective structure under blasting loads were numerically simulated by applying ANSYS/LS-DYNA.The energy distribution regulation shows that the foam concrete has greater effects of the reflection and absorbing energy,and changes the energy distribution in the protective structure.The more energy is absorbed by top layers,the energy in the bottom layer is only 14% of that in the structure without absorbing energy layer. |
