为探究两种防护装甲的防护能力,设计了4组四面简支板构件,其中1组进行静力加载试验、3组进行有防护装甲和无防护装甲的飞射物模型撞击试验。静力加载试验中量测并分析了构件的挠度,观测记录加载过程中的裂缝开展情况,最终得到构件的极限承载力。飞射物模型撞击试验中量测并分析了飞射物的加速度和构件破坏情况。通过分析对比,结果表明:剪切增稠液体装甲能明显吸收飞射物的动能、有效降低飞射物的峰值加速度,达到防护效果;波纹钢板-泡沫铝防护装甲对飞射物的峰值加速度降低基本无影响,但能够通过减小界面损坏和扩大撞击力作用面积降低板的破坏程度。
In order to explore the protective capability of two kinds of protective armor, four groups of four-sided simple support members were designed. One group was subjected to static loading test and the other three groups were tested by impact model of the projectile with protective armor and unprotected armor. In the static loading test, the deflection of the member is measured and analyzed, and the development of cracks in the loading process is observed and finally the ultimate bearing capacity of the member is obtained. In the impact test of the fly model, the accelerations of the flying objects and the damage of the components were measured and analyzed. Through the analysis and comparison, the results show that the shear thickening liquid armor can obviously absorb the kinetic energy of the flying object, effectively reduce the peak acceleration of the flying object and achieve the protective effect; the peak acceleration of the corrugated steel plate - the aluminum foam protective armor reduces the flying object Basically no effect, but can reduce the extent of damage to the board by reducing interface damage and expanding the area of impact force.
