摘　　要：利用聚能射流对约束及非约束陶瓷靶开展抗侵彻性能系列实验研究,分别获取了约束陶瓷靶和非约束陶瓷靶抗射流侵彻过程的P-t曲线和在验证靶上剩余穿深,并同时与45#钢抗侵彻数据进行对比.基于实验结果分析了不同靶板抗射流侵彻规律.实验结果表明:约束和非约束陶瓷的质量防护系数均优于45#钢;约束陶瓷的抗射流侵彻能力大大优于非约束陶瓷.Anti-penetration experiments of confined AD95 ceramic targets by shaped charge jets have been carried out. The P-t curve and residual penetration depth on validated targets based on DOP （depth of penetration） was obtained, as well as corresponding experiment data of 45^# steel in order to contrast the protection ability of the ceramic targets. Anti-penetration ability of these targets to different velocity jets has been achieved based on experiment results. The experiment results showed that ceramic targets have higher protection ability than 45^# steel, and that confined ceramic targets have excellent protection ability compared to unconfined ceramic targets to jet penetration.
