隔板对双层平行反应装甲金属板运动影响

摘要

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 influence 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 37％ or so when the spacer is close to the upper back plate.%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％.
