为给空投装备提供理想的缓冲装置,在利用相关等效理论对不同缓冲装置进行合理等效的基础上,应用ABAQUS 软件建立了某空投装备的有限元模型,分析了该空投装备在不同缓冲装置下的着陆冲击响应。 根据破损边界理论,对比分析了不同缓冲装置的缓冲性能。 根据分析结果提出了组合式缓冲装置的构想,并对其进行了仿真分析。 仿真结果表明:组合式缓冲装置较其余 2 种缓冲装置具有较好的缓冲性能。

A model of the airdrop equipment was set up using ABAQUS based on equivalent theory. The process of landing impact was analyzed on different buffer device. The cushioning property of different buffer device was evaluated according to damage boundary theory. The idea of combination buffer device was put forward according to the analysis result. Simulation analysis was carried out on the combination buffer device. The simulation results showed that the combination buffer device's cushioning property is the best in the three buffer devices.
