摘要: 蜂窝夹层结构因优异的耐撞性能和吸能能力,被广泛用于航空航天、汽车工业和船舶等领域。然而,蜂窝夹层结构在服役过程中很容易遭受到各种速度的冲击,这些冲击可能会导致蜂窝夹层结构性能的下降甚至损坏。因此对蜂窝夹层结构进行试验以及仿真分析,研究蜂窝夹层结构的抗冲击性能以及冲击过程十分重要。本文从蜂窝夹层结构冲击试验及仿真方面对国内外的研究成果进行了归纳和总结,在试验研究中总结了低速冲击和高速冲击的试验方案,包括摆锤冲击试验、落锤冲击试验以及空气炮试验。在仿真方面,从蜂窝夹层结构的建模、材料的损伤失效、冲击过程以及结构参数对冲击性能的影响等方面进行了汇总分析。最后对蜂窝夹层结构的冲击试验及仿真的研究趋势进行了展望。

Abstract: Honeycomb sandwich structures have been widely used in aeronautics, automotive and marine industry because of their excellent crashworthiness performance, fatigue resistance and energy absorption ability. The honeycomb sandwich structure is susceptible to various speed impacts during service, and these impacts would cause the performance of the honeycomb sandwich structure to decrease or even be damaged. Therefore, it is very important to test and simulate the honeycomb sandwich structure to study the impact resistance and impact process of the honeycomb sandwich structure. This article summarizes the impact test and numerical simulations of honeycomb sandwich structures at home and abroad. In the experimental study, the low-velocity impact and high-velocity impact test scheme are summarized, including Charpy impact test, drop impact test and gas gun test. At the same time, in the simulation research, the modeling of honeycomb sandwich structure, the damage and failure of composite materials, the impact process and the influence of structural parameters on the impact performance are summarized. Finally, a preliminary prospect on the future development direction of the honeycomb sandwich structure impact experiment and simulation is given.
