目的 改进中件空投平台结构设计及主体材料，以改善空投物资着陆缓冲效果，提高空投可靠性。方法 以中件空投平台结构、材料为研究对象，借助空投实验，完成缓冲包装材料的合理选择和空投平台结构的优化设计。结果 设计了上、中、下3层的缓冲结构，并合理确定了各层的材料选择，改进后的中件空投平台空投可靠性得到了大幅提高。结论 通过改进空投平台结构设计及平台缓冲材料，可满足中件物资空投的要求，确保了空投着陆后物资的完好和正常使用，提高了空投平台结构的稳定性和抗冲击力。

It aims to improve the airdrop structure design and the main materials, thus to improve airdrop landing buffering effect and upgrade the reliability of the drop. With airdrop platform structure and material as the research object, cushioning packing materials were selected reasonably and the design of airdrop platform structure was optimized by the airdrop experiment. The three-layer buffer structure (upper, middle and lower) was worked out and materials for each layer were properly determined. The improved airdrop platform had greatly upgraded reliability. In conclusion, the improvement of airdrop platform structure design and cushioning materials can meet the requirements on middle-sized pack airdrop, guarantee the intact and normal use of airdrop supplies and improve the stability and impact resistance of airdrop platform structure.
