摘要:

为分析靶体结构对其抗侵彻特性的影响,利用轻气炮进行平头杆弹正撞击单层板和等厚接触式三层板的实验, 获取相关的撞击过程图片．通过撞击实验,得到这两种结构靶体的初始-剩余速度曲线以及弹道极限,撞击速度为190～450 m／s．研究靶体结构对抗侵彻特性的影响,包括靶板的失效模式和抗侵彻性能．最后,采用ABAQUS／EXPLICIT软件对杆弹撞击金属板的过程进行数值模拟研究,通过对比数值模拟和实验结果,验证了数值模拟材料模型和参数的有效性．结果表明:多层板的弹道极限高于等厚单层板,并且多层板和单层板的主要失效模式之间存在差异．对于多层板,靶板失效模式与其在靶中位置相关．

Abstract:

In order to investigate the influence of configuration of target on the ballistic performance, monolithic and three-layered targets were normally impacted by blunt-nosed projectiles in the velocity range of 190～450 m／s with the help of a gas gun, and also the photos of the impact process were obtained. Based on the tests, the residual velocity versus the initial velocity curves of the projectiles were constructed, and also ballistic limit velocities were obtained. The influence of combination configuration of target on the ballistic characteristic, including the ballistic resistance and failure models were investigated. Moreover, the penetration process of metal plates impacted by rod projectiles had been studied with numerical simulation code ABAQUS／EXPLICIT, and also the validation of models and parameters of materials had been proved by comparing the experiment results with numerical simulations. The results indicated that the ballistic limit velocity of multi-layered target was higher than that of monolithic target, and also there were differences between failure models of multi-layered targets and monolithic target. Moreover, the failure models of plates of multi-layered targets were in relation to their order.
