摘要
针对PELE斜侵彻均质靶板问题,在AUTODYN-3D平台下用数值模拟方法研究了斜侵彻下着角和其它参数对PELE破片杀伤和穿甲双重终点效应的影响.结果表明,在PELE能够贯穿靶板前提下,着角越大,产生的横向效应越明显,且轴向速度呈下降趋势.得到了斜侵彻情况下靶板厚度、靶板材料和弹着速对PELE终点效应的影响规律,以及当着角改变时,靶板厚度、靶板材料和弹着速对PELE终点效应的敏感度变化规律.
The numerical simulation of penetrator with enhance lateral efficiency（PELE） penetration into oblique homogeneous target has been carried out to investigate the comprehensive terminal effects of PELE, including penetration and fragments damage. The results demonstrate that the lateral efficiency of PELE sharpens and the residual velocity declines when the angle of attack increases. It is observed that the PELE terminal effect is affected by parameters of target thickness, target material and impact velocities. In addition, when the angle of attack increases, the changing trend of the sensibility of PELE terminal effect can be estimated with the changes of parameters mentioned above.
