| 摘 要： | 设计并进行了7.62mm穿甲子弹侵彻陶瓷/低碳钢复合靶板的弹道试验,得到了极限速度及陶瓷锥底部半径等数据。分析了锥底半径与入射速度、面板及背板厚度的关系,着重分析了偏心入射时靶板的抗弹机理。结果表明:陶瓷锥可分为破碎区和粉碎区,粉碎区半径约为面板厚度与弹丸半径之和;当弹着点距离陶瓷面板边缘大于5mm时,靶板的抗弹性能变化不大,而弹着点位于距陶瓷面板边缘小于5mm的板边区时,抗弹性能明显降低,靶板的有效防护面积应扣除板边区。

| Abstract: | Ballistic experiments of ceramic/mild steel composite target against 7.62mm armor-piercing projectile(APP) were designed and carried out.Limit velocities and the base radiuses of ceramic cone were obtained.The influence of projectiles initial velocity,the thickness of front and rear plate on the base radius of ceramic cone and the impact point to the resistant mechanism of target were analyzed.The results show that the ceramic cone can be separated into fragmentation and smash region,the base radius of which approximates the thickness of front plate plus projectile radius.The ballistic performance of composite target area is in a similar case except for an edge area(5mm to the edge of the target),in which the ballistic performance declines obviously. The edge area has to be discarded from the effective protective area. |
