摘要

摘要: 利用ANSYS/LS-DYNA程序，对金属射流侵彻4层剪切运动等厚间隔靶板的过程进行了数值模拟研究。从射流破裂形态、能量损失幅值、后效靶板上的穿深形貌等3个角度，分析了运动靶板对射流的干扰特性，得到了靶板的运动速度、射流入射角度对4层剪切运动间隔靶板对射流破甲性能的影响规律。结果表明，在靶板运动速度从零提高至300 m/s的过程中，靶板对射流的干扰能力逐步提高，但运动靶板速度在从零提高到100 m/s时，对射流的干扰程度变化较快，速度再提高时，干扰程度变化较缓。运动靶板对射流的干扰能力随着射流入射角度的增大而呈递增趋势。

Abstract: Numerical simulation with ANSYS/LS-DYNA software was accomplished on metal jet being disturbed by shearing movement of four-layer equivalent spaced plates. Disturbing performance of moving plates was analyzed according to jet rupturing forms, energy losing values, and the penetrating depth in target plate. The effects of the plates-velocity and the impact angle on the disturbing performance were obtained. The obtained results are as follow: the increasing of the plate velocity can improve the disturbing ability on jet; the disturbing efficiency was greater with the plates velocity beneath 100 m/s than over 100 m/s; and the disturbing extent can increase with the increase of the impact angle. All those results are significant for mechanical armoring research.
