摘要
为了研究侵爆弹炸点深度与典型地下工事毁伤效应的关联性,采用True Grid建模软件建立不同侵彻深度混凝土内爆炸的有限元模型,应用LS-DYNA3D软件进行仿真计算,综合分析了装填14.7 kg炸药在不同深度对6 m厚混凝土工事毁伤破坏情况,得到最佳爆炸剩余厚度为0.8 m,为0.13~0.20倍混凝土靶板厚度,通过试验验证,试验结果与数值计算结果吻合,研究结果可为侵爆弹炸点设计及典型地下防御工事设计提供技术借鉴。
In order to study the correlation between the burst depth and the damage of typical underground constructions,True Grid modeling software was used to establish a finite element model of internal explosion in concrete with different burst depths.The LS-DYNA3 D software was used for calculation and analysis.14.7 kg of explosive at different depths were packed to damage 6 m thick concrete fortifications,the optimal remaining thickness of the explosion is 0.8 m,which is about 0.13~0.20 times the thickness of the concrete target plate.Through experimental verification,the test results agree with the numerical calculation results.The results provide technical reference for the design of earth-penetrating projectile and typical underground defenses.
