摘　　要：研究了不同倾角时,折状夹芯倾角为45°的复合靶板的抗射流侵彻性能。基于射流侵彻复合靶板过程中的能量损失、后效靶剩余穿深以及复合靶板质量防护系数,研究了无天然橡胶填充和有天然橡胶填充两种情况下的靶板性能,分析了具有橡胶填充靶板各组成部分的吸能特性。通过基准弹侵彻后效靶和射流以60°侵彻具有橡胶填充靶板的实验研究,验证了仿真结论的可靠性。研究表明,具有45°折状夹层结构的靶板有很好的抗射流侵彻能力,填充橡胶对提高靶板的防护性能是有利的,该结构复合靶板具有优异的防护性能,可以作为一种新型轻型防护装甲。The anti-penetration property of the corrugated sandwich composite armor with the corrugation angle of 45° in different penetration angles was studied. The performance of the armors filled with rubber and without rubber was studied, based on the energy loss,DOP and quality protection factor considerations. The energy absorption characteristics of the armor filled with rubber was analyzed. The reliability of the simulation results was validated by Ф56 mm stander shaped charge penetrating the steel at 0° dip angle and the composite armor at 60° dip angle. The results showed that the protection capability of the corrugated sandwich composite armor with beneficial to fill the corrugation gaps with rubber. This kind of capability and can be used as a new kind of light armor. corrugation angle of 45° was effective. It＇s composite armor has excellent protection
