摘要

在装甲车里的部队的安全是最重要的。对装甲车最严重的威胁是埋药爆炸或简易爆炸装置。在装甲车辆验证中使用数值方法可以最大限度地减少所需原型的数量并加快设计过程。本研究的重点是利用ConWep(代表常规武器)方法对ALM(代表反地雷)车辆中用于爆炸防护的STRENX装甲钢进行爆炸模拟。采用Johnson-Cook塑性模型将板建模为可变形实体。本文对装甲车辆上的防护板进行了检验,以确定何种几何形状能提供最佳的防护条件。对三种不同的几何形状进行了数值测试,其中两种代表组合几何形状。选取保护板中心节点的塑性应变最大值和垂直位移最大值作为参数来表示得到的结果。

FEM Analysis of Anti-Mining Protection of Armored Vehicles
: The safety of the troop in an armored vehicle is paramount. The most serious threat to armored vehicles is a buried charge explosion or an improvised explosive device. The use of numerical approaches in the validation of armored vehicles minimizes the number of prototypes needed and speeds up the design process. This research focuses on blast simulation utilizing the ConWep (which stands for conventional weapon) method for STRENX armor steel used for blast protection in ALM (which stands for anti-landmine) vehicles. The plate is modeled as a deformable solid with the Johnson-Cook plasticity model. In this paper protective plates were examined in order to determine which geometry gives the best protective conditions for the troop in an armored vehicle. Three different geometries were numerically tested, and two of them represent combined geometry. The maximal value of the plastic strain and maximal value of the vertical displacement of the central node on the protective plate was chosen as the parameters to represent the obtained results.
