摘要

多弹丸同时撞击目标时，弹靶相互作用过程及剩余速度与单弹丸撞击存在显著差异，单弹丸结论难以直接推广至多弹丸撞击场景，而现有关于多弹丸撞击的研究也多为定性分析。为揭示多弹丸撞击动态响应过程，以2024铝合金靶板为研究对象，基于试验验证的数值仿真模型，开展刚性多弹丸对铝合金靶同时多重撞击研究。结果表明，随撞击速度增加，靶板损伤由累积损伤过渡为叠加损伤，不同撞击速度对应的靶板累积损伤机制不同。撞击速度较高时，靶板损伤更易受弹丸个数的影响，随弹丸个数的增加，损伤由叠加损伤过渡为累积损伤。同时建立多弹丸平均剩余速度的理论公式，其平均相对误差为3.35%。研究成果可为多重撞击毁伤效应评估与防护结构优化设计提供理论依据。

Abstract

The interaction mechanics and residual velocities associated with simultaneous multi-projectile impact are profoundly disparate from the single-projectile case. As such

the single-projectile paradigm does not lend itself to direct extrapolation

while the existing body of literature on this multi-impact phenomenon remains largely qualitative.To elucidate the dynamic response process and damage evolution mechanisms under multi-projectile impact

a study was conducted on the simultaneous multiple impacts of rigid projectiles on 2024 aluminum alloy targets using a numerically simulated model validated by experiments.The results indicate that as impact velocity increases

target damage transitions from a cumulative damage effect to an additive damage effect. The mechanisms of cumulative damage effects vary under different impact velocities. At higher impact velocities

target damage becomes more susceptible to the number of projectiles; as the number of projectiles increases

the damage shifts from an additive damage effect to a cumulative damage effect. Additionally

a theoretical formula for the average residual velocity of multiple projectiles was established

with a mean relative error of 3.35%. The findings provide a theoretical basis forassessing damage effects under multiple impacts and for optimizing protective structure design.
