不同截面形式的柱状薄壁结构，其缓冲性能存在一定差异。基于ABAQUS/Explicit程序，对不同截面形式的柱状薄壁结构动态变形过程进行了有限元仿真，并在结构材料用量相同的条件下，简单比较了各种截面形式对动能吸收能力的差异。研究方法对缓冲包装设计等具有一定的参考价值。

Columnar thin walled structure with different cross sectional shape has different cushioning performance. Finite element simulation of dynamic deformation process of columnar thin walled structure with different cross sectional shape was carried out using ABAQUS/Explicit program. The energy absorption capability of columnar thin walled structure with different cross sectional shape under the same material consumption was compared. The purpose was to provide reference for design of cushioning package.
