摘要(Abstract):

针对信息化条件下坑道头部结构战时生存面临的挑战,对爆炸冲击作用下坑道头部结构的毁伤情况进行了试验研究。通过动力有限元软件LS-DYNA模拟了爆炸冲击对坑道头部结构的作用过程,将得到的结构毁伤情况与试验结果进行对比分析,二者比较接近,可为坑道结构的设计及毁伤模式研究提供参考。
In view of the challenges to the wartime survival under the informationization condition,the sap depot head′s destruction pattern caused by explosion was tested and studied.LS-DYNA was used to simulate the blast effect process.The results were similar to the experimental ones,showing that the simulation can be used as a reference for the design of sap depot structure and the study of destruction pattern.
