摘　　要：运用LS-DYNA动力学分析软件,对具有不同橡胶夹层厚度的陶瓷/橡胶/钢复合靶在30°和60°倾角下的射流侵彻情况进行了数值模拟。采用聚能装药基准弹,进行了剩余穿深实验,研究了射流侵彻陶瓷/橡胶/钢复合靶后射流速度、靶板变形和剩余穿深,分析了倾角和橡胶夹层厚度对复合靶抗射流侵彻性能的影响机理。结果表明:射流侵彻陶瓷/橡胶/钢复合靶的性能受倾角的影响很大,尤其是在大倾角下影响更为显著;橡胶夹层对射流侵彻性能有一定的影响,但其厚度的变化对射流侵彻性能的影响很小。Numerical simulation and analysis of jet penetration in ceramic/rubber/steel composite armor with different rubber interlayer thicknesses at the impact angles of 30° and 60° were conducted by applying LS-DYNA dynamic analysis software. The jet velocity,target deformation and remaining penetration depth were obtained through the standard shaped charge experiment, and the effects of inclination angle and rubber interlayer thickness on the anti-jet penetration property of composite armor were analyzed. The results show that the inclination angle has a great influence on the defense property of ceramic/rubber/steel composite armor against shaped charge jet, especially large inclina- tion angle;the rubber interlayer has a certain impact on the penetration performance of jet, however the effect of its thickness is quite small.
