摘要
为研究侵爆弹对框架类建筑物的毁伤效果,利用LS-DYNA有限元程序对单枚侵爆弹打击四层五跨建筑物进行了数值模拟。该程序利用流固耦合算法来模拟炸药对建筑物的毁伤,为了验证该算法的有效性,进行了房屋内爆炸试验和试验原型数值模拟,房屋内爆炸试验结果与数值模拟结果吻合,验证了该方法的合理性。利用该程序对侵爆弹打击四层五跨建筑物进行了数值模拟,结果表明炸点在第2层走廊中心时建筑物毁伤等级为中度毁伤,为目标毁伤效果评估工作提供了一定的参考。
In order to study the damage effect of the invading warhead on frame buildings,the LS-DYNA finite element program is used to simulate the single intrusion warhead striking the fourstory and five-span buildings.The program uses a stream solid-coupled algorithm to simulate the damage to the building,to verify the effectiveness of the algorithm.The numerical simulation of the explosion test and test prototype of the house are carried out.The explosion test results,compared with the numerical simulation results,verify the rationality of the method.Then the program is used to simulate the single intrusion warhead striking the four-story and five-span buildings,when the friction point is in the second layer corridor center,and damage level is moderate damage.It provides a certain reference for the target damage effect assessment work.
