When analyzing the penetration of a rod-shaped projectile in semi-infinite target, the velocity gradient of the shaped charge jet is taken into account. The jet is divided into a series of segments, and the variations of the length and diameter of each jet segment are calculated at the moment of impacting on the target. Through the Bernoulli equation, linear approximations of velocity and diameter of the jet, and static method, the relationship between penetration depth and hole diameter in the target and impacting jet is obtained. Moreover, the simulated results are in quite good agreement with the experimental data.

理论分析高速杆式射流侵彻半无限靶过程时,考虑速度梯度对聚能射流的影响,将射流进行分段计算,得到了射流拉伸后实际碰靶时的微元长度和直径变化。采用伯努利方程和静力学方法,通过对射流形状和速度分布作线性近似,理论分析了高速杆式射流侵彻半无限靶的过程,得到了靶体中的侵彻深度和侵彻孔径与射流长度、速度及直径之间的关系。将模拟结果与实验结果进行对比,结果表明理论分析结果与侵彻实验结果符合较好。

理论分析高速杆式射流侵彻半无限靶过程时,考虑速度梯度对聚能射流的影响,将射流进行分段计算,得到了射流拉伸后实际碰靶时的微元长度和直径变化。采用伯努利方程和静力学方法,通过对射流形状和速度分布作线性近似,理论分析了高速杆式射流侵彻半无限靶的过程,得到了靶体中的侵彻深度和侵彻孔径与射流长度、速度及直径之间的关系。将模拟结果与实验结果进行对比,结果表明理论分析结果与侵彻实验结果符合较好。

杆式射流  /  侵彻  /  半无限靶  /  侵彻深度  /  侵彻孔径

When analyzing the penetration of a rod-shaped projectile in semi-infinite target, the velocity gradient of the shaped charge jet is taken into account. The jet is divided into a series of segments, and the variations of the length and diameter of each jet segment are calculated at the moment of impacting on the target. Through the Bernoulli equation, linear approximations of velocity and diameter of the jet, and static method, the relationship between penetration depth and hole diameter in the target and impacting jet is obtained. Moreover, the simulated results are in quite good agreement with the experimental data.
