摘　　要：目的综述以木材、聚氨酯泡沫、蜂窝铝作为核乏燃料运输容器减震器填充材料的性能。方法通过对3种填充材料的减震器进行受载分析,然后对3种填充材料的力学性能进行验证。结果将3种材料作为核乏燃料减震器填充材料具有可行性,还列出了3种材料的不足之处。结论工业上对有着优秀能量吸收、限制过载、质轻且受环境变化影较小的核乏燃料运输容器减震器填充材料有着迫切需求。之后提出将2种材料(泡沫铝和双向瓦楞蜂窝铝)作为减震器的填充材料,并分析了2种材料的特点与吸能特性,证明了其作为减震器填充材料的合理性与可行性。The work aims to review the properties of wood,polyurethane foam,and honeycomb aluminum as filling materials for impact limiters of nuclear spent fuel transport cask.The impact limiters of the three filling materials were subject to load analysis,and then the mechanical properties of the three filling materials were verified.The three materials had the feasibility of being used as filling materials for impact limiters of nuclear spent fuel,and their shortcomings were also obtained.There is an urgent need in the industry for the filling materials of nuclear spent fuel transport cask impact limiters with excellent energy absorption,limited overload,light weight and less environmental impact.Later,it is proposed to use two materials(aluminum foam and bi-directional corrugated honeycomb aluminum)as impact limiter filling materials,and their characteristics and energy absorption are analyzed to prove the rationality and feasibility of these materials as impact limiter filling materials.
