摘要: 根据射流侵彻橡胶复合靶板后射流变形情况,将橡胶复合靶板抗射流侵彻过程分为4个阶段。基 于应力波传播理论和开尔文-亥姆霍兹不稳定性对橡胶复合靶板抗射流侵彻过程进行了理论分析,得到射流 失稳时射流的速度区间及橡胶复合靶板对射流的干扰频率,并分析了射流侵彻橡胶复合靶板后的剩余侵彻 能力。分析了橡胶夹层厚度变化和橡胶复合靶板倾角对橡胶复合靶板抗射流干扰的影响,得到最佳橡胶夹层 厚度和倾角,并通过实验对理论结果进行了验证。结果表明,开尔文-亥姆霍兹不稳定性能很好地分析橡胶复 合靶板对射流的干扰作用。橡胶复合靶板在倾角为60、橡胶夹层厚度为3~3.5mm 时具有最佳防护性能。Abstract: Theprocessofrubbercompositearmorantishapedchargejetpenetratedwasdividedfour partsbasedonthejetdeformationwhentheshapedchargejetpenetratedtherubbercompositearmor.
