摘要
抗冲击地砖具有超弹性大孔隙率蜂窝薄壁结构。建立抗冲击地砖的周期性薄壁结构单胞模型,进行冲击响应分析。结果表明,抗冲击地砖在压缩过程中具有明显的应变平台期,能够在一定载荷范围内提供足够的支撑刚度;在载荷强度达到一定值时,该结构能够被迅速压溃,产生瞬态大变形而吸收冲击能量。因此,抗冲击地砖是一种理想的舰员冲击防护手段。
Based on the analysis of the hyperelastic characteristics of the honeycomb structure of ground tiles for anti-shock protection of warship＇ s personnel, the single cell model for periodic cellular structure was established, and its deformation behavior in dynamic compression and shock conditions was studied. Simulation results show that the anti-shock ground tiles have enough strength and rigidity to bear the load from personnel＇ s activities of the warship, while they can be crushed rapidly under shock load so as to absorb large amount of shock energy due to their preferable strain plateau phase.
