待机库防弹性能数值模拟分析

Numerical simulation to resist projectile on shelter for mobile vehicles

为了确定新型待机库的防弹性能,根据待机库的结构特点,利用ANSYS/LS-DYNA有限元软件,对待机库结构和材料的抗弹性能进行了数值计算。结果表明,弹体对拱形结构的侵彻,可用弹体对平板结构的侵彻来模拟;由3层0.12m厚刚玉块石和C40混凝土构成的刚玉块石固结体,能有效抵抗MK83弹体的侵彻。

To confirm the protective capability the new type shelter of mobile vehicles,the performance of the structure and material against projectile was computed and analyzed by using the ANSYS/LS-DY-NA finite element software, based on its design feature.The results show that penetration of the projectile into arched structure can by simulated by that into plane plate,and the corundum-rubble induration made of C40 concrete and 0.36m thick corundum-rubble repeated addition 3 layers can resist the penetration of the MK83 bomb.
