摘要：

针对壳体泡沫铝模型在几何建模及仿真计算中存在的问题，基于Voronoi模型提出了具有随机壁厚的三维实体泡沫铝模型的建模方法及其实现流程。通过使用Python语言编写的ABAQUS泡沫铝建模插件建立了实体泡沫铝模型，进行了泡沫铝的准静态压缩有限元仿真分析。对实体模型和壳体模型在仿真中的力学行为、变形模式及计算所得的材料应力-应变曲线进行了对比分析。研究结果表明：实体模型的仿真结果和变形模式与实验更接近；实体模型计算得到的应力-应变曲线波动更小、更加平滑；实体模型较壳体模型在压缩过程中受力和内部结构的模式更加合理。

Abstract:

To solve the problems existing in geometric modeling and simulation calculation of shell aluminum foam model， based on the theory of Voronoi model， the modeling method and its implementation process of 3D solid aluminum foam model with random cell wall thickness are put forward. The model of solid aluminum foam is established by using ABAQUS foam aluminum modeling plug-in program written in Python language， and the quasi-static compression finite element simulation analysis of aluminum foam is carried out. The mechanical behavior， deformation mode and the calculated stress-strain curve of solid model and shell model in simulation are compared and analyzed. The results show that the simulation results and the deformation mode of the solid model are closer to the experiment， the stress-strain curve of the solid model is smoother and it has smaller fluctuations， the solid model is more reasonable than the model of the shell model in the compression process.

Key words: metallic material, closed-cell aluminum foam, Voronoi model, random cell wall thickness, solid model, quasi-static compression
