摘要
研究了3.3 g立方体高速钢制破片对不同厚度的高强聚乙烯纤维模压层合板的侵彻。根据弹道试验结果和理论分析进一步确定了弹道极限速度vBL与面密度ρad的线性关系;又将剩余速度vr的经验关系式中的相关参数表示为ρad的函数,得到了vr与aρd的经验关系式。经验关系式的预测值都与试验结果有较好的吻合,可以将此经验公式用于对立方体破片侵彻高强聚乙烯纤维层合板剩余速度和弹道极限速度的预测。
The different thickness UHMWPE FRP（URP） laminates impacted by 3.3 g cubic high velocity fragments were studied.According to the ballistic experimental results and the theoretical analysis,the linear relation between ballistic limit vBL and area density ρad was confirmed;the versatile experiment relation between vr and ρad was found based on that relative parameters in the experiential relation of residual velocity were expressed by the function of ρad.The predicted values of vr and vBL of the cubic high velocity fragments impacting URP using the experiential relations are consistent with the experimental results.The two experiential relations can be used for predicting residual velocity and ballistic limit of the cubic high velocity fragments impacting URP.
