剩余速度与靶板厚度关系的研究

Research for the relations between residual speed and target thickness

采用改变靶板厚度的方法 ,测量了约在相同速度的条件下钨合金 10 5模拟穿甲弹侵彻不同厚度 4 5 # 钢板后的剩余速度。实验结果表明 ,随着靶板厚度的增加 ,穿过靶板弹体的剩余速度呈缓慢下降趋势 ;弹孔直径增加 ,随后保持不变 ;测量弹体剩余速度实验中得到的弹体最大穿深 。

By changing target board thickness,the residual speed was measured after the tungsten alloy 105 simulative penetrator penetrated 45 # steel with different thickness at the same speed.The test results show that the residual speed of the penetrator drilling through target tended to slow down as the target thickness increased;the crater diameter growed and then kept invariable;the ultimate penetrating depth got in measuring residual speed of penetrator,is larger than the ultimate penetrating depth in integral target in the same experiment.
