针对爆炸载荷作用下外层结构防护能力加强问题，对四边固定的具有不同加强筋类型的平板在爆炸冲击载荷作用下的动态响应问题进行了数值仿真研究。利用ABAQUS软件建立了4种平板的有限元模型，仿真计算了平板在爆炸载荷作用下的响应，比较分析了平板的能量分布、平板中心点处的最大挠度值及应力分布等特性。结果表明，单纯地在平板背面添加加强筋数量对于抗爆性能的提高意义不大；所设计的4类平板中，由加强筋耦合成三角形的平板抗爆性能最佳。
For enhancing the explosion resisting performance of the outer structure, the dynamic response of plates with different stiffeners under the explosion loading is numerically simulated. The plates are with their four sides fixed. Finite element models for four kinds of plates are built using the ABAQUS software, to simulate the dynamic response. The energy distribution, the maximum deflection at the plate center and the stress distribution are analyzed and compared. To resist the explosion loading, the increased number of stiffeners does not mean a better performance. Among the four plates with different stiffeners, the triangle stiffener coupled plates are the best one for the anti-explosion performance.
