防雷靴防护性能的分析计算

Analys is and calculation of the protective performance of the mine boot

根据GGF110型防雷靴的基本参数和有关实验数据,采用三维动态非线性有限元分析软件穴ANSYS/LS-DYNA雪,对该防雷靴受58式防步兵地雷爆炸冲击作用下的破坏与变形过程进行了分析和计算。包括58式反步兵地雷在土中的爆炸过程、防雷靴靴底结构对爆炸冲击波的前期响应过程。结果表明:(1)防雷靴的整体设计合理;(2)双层″V″型板结构设计、“桁架”式缓冲减震的结构设计以及“门”型和倒“L”型结构设计,具有很好的阻挡、分离和缓冲爆轰冲击波的作用。

The study is based upon parameters of GGF110antipersonnel mine protective combat boots and the experiments involved.The ANSYS/LS-DYNA software is applied toanalyzing and calculating the destructive and distorting effects tothe boots by the detonation of58anti-infantry mine,which includes the explosive process of the mine and early-stage response of the protective boot soles tothe blast waves.It suggests that the overall design of the mine boots is reasonable and that a desirable outcome is guaranteed through double″V″plate and purlin-frame buffering damping structure with door-shaped and top-down″L″design in prevention,block and absorption of blast waves.
