摘　　要：目的以蜂窝铝夹芯板为研究对象,分析其对φ8 mm氧化锆陶瓷破片低附带毁伤元冲击响应特性。方法首先通过弹道枪试验,获得氧化锆陶瓷破片正侵彻和30°斜侵彻蜂窝铝夹芯板的弹道极限,然后使用有限元方法探究不同着角下蜂窝铝夹芯板的冲击响应特性与抗变形能力,对比分析破片直径对蜂窝铝夹芯结构冲击响应特性的影响。结果φ8 mm氧化锆陶瓷破片对铝蜂窝夹芯板正侵彻弹道极限速度为236.5 m/s,着角为30°的斜侵彻弹道极限速度为276.5 m/s。直径近似蜂窝单元跨度的破片,破片直径越大,斜侵彻角度对蜂窝铝夹芯板击穿比动能的影响越小。相同着角下,氧化锆陶瓷破片直径越大,击穿蜂窝铝夹芯板所需的比动能越小。结论得出了铝蜂窝夹芯板对陶瓷地附带毁伤元的冲击响应特性规律,研究结果可为反卫星和反航天目标战斗部的设计提供参考。The work aims to take honeycomb aluminum sandwich panel as the object to analyze its impact response characteristics to low collateral damage element ofφ8 mm zirconia ceramic fragments.Firstly,the ballistic limit of zirconia ceramic fragments penetrating into honeycomb aluminum sandwich panel at normal and 30°oblique angles was obtained by ballistic gun test.Then,the impact response characteristics and deformation resistance of honeycomb aluminum sandwich panel at different angles were explored by finite element method,and the effect of fragment diameter on the impact response characteristics of honeycomb aluminum sandwich structure was compared and analyzed.The vertical penetration ballistic limit velocity ofφ8 mm ceramic fragments into aluminum honeycomb sandwich panel was 236.5 m/s,and the oblique penetration ballistic limit velocity with an impact angle of 30°was 276.5 m/s.For the fragments with a diameter similar to the span of a honeycomb unit,the larger the diameter of the fragment,the smaller the impact of the oblique penetration angle on the specific kinetic energy of the honeycomb panel for breakdown.At the same oblique angle,the larger the diameter of ceramic fragments,the smaller the specific kinetic energy required to penetrate honeycomb aluminum sandwich panel. The impact response characteristics of aluminum honeycomb sandwich panel to ceramic low collateral damage element are obtained and the research results can provide reference for the design of anti-satellite and anti-space target warheads.
