摘要
为研究隔板存在对双层平行反应装甲各金属板运动情况的影响,采用Lagrange Autodyn-3D建立模型,并进行数值仿真,仿真结果发现:隔板存在对上层反应装甲面板的速度及位置影响不大;隔板紧贴上层反应装甲背板时,下层反应装甲面板的速度和位置均为最小,速度减小约59.7%,位置降低约37%。
To study the influence of spacer on double parallel explosive reactive armor（ ERA） metal plate movement, the Lagrange Autodyn-3D software is used for its modelling and numerical simulation. The result shows that the existence of spacer has little influ-ence on the speed and location of upper ERA front plate and the speed of the lower ERA front plate is minimal reduced by 59.7% or so its and position is lowest reduced 3 7 % or so when the spacer is close to the upper back plate.
