Characterization of Material Collapse and Energy Absorption in Aircraft Safety Zone Characteristics

机场道面安全区特性材料的溃缩吸能指标对保障飞机安全起降具有重要意义。为评价泡沫混凝土特性材料的溃缩吸能特征,通过对单轴压缩实验、侵彻实验、真机实验、单轮摆锤实验及单轮负载实验等表征方法进行分类总结,并探析不同表征技术的优缺点,提出特性材料溃缩吸能的表征技术研究方向,从而更准确地模拟被飞机压溃后的吸能效果。

The energy absorption index of the characteristic material of airport pavement safety zone is of great significance to ensure the safe take-off and landing of aircraft.In order to evaluate the collapsibility and energy absorption characteristics of foam concrete characteristic materials, the characterization methods such as uniaxial compression experiment, penetration experiment, real machine experiment, single wheel pendulum experiment and single wheel load experiment were classified and summarized, and the advantages and disadvantages of different characterization techniques were analyzed, and the research direction of collapsibility and energy absorption of characteristic materials was proposed, so as to more accurately simulate the energy absorption effect after being crushed by aircraft.
