| 泡沫铝作为一种新型的结构功能材料，具有较好的阻热、降噪和能量吸收性能。基于Matlab的Random函数，应用贪心算法和孔径无限迭代原理建立闭孔泡沫铝三维随机球模型，解决了当前泡沫铝三维建模中存在的孔隙率低、计算复杂、运算成本高、仿真模拟实现程度低等问题，得到了孔隙率达90%的泡沫铝模型，实现了模型与有限元软件的衔接，为泡沫铝模型优化及物理性能分析提供了一种有效的数值方法。将模型进行拓展应用，可得到泡沫铝夹层板模型和泡沫铝复合材料等，用于如汽车防撞梁、建筑材料、噪声屏障板等结构的计算机仿真模拟及相关研究工作。 |

| As a new type of structural and functional material, foamed aluminum has good heat resistance, noise reduction, and energy absorption. Based on the rand function of Matlab, a three-dimensional random ball model of closed cell aluminum foam was established by greedy algorithm and infinite iteration principle. The problems, including low porosity, complex calculation, high computational cost and low simulation level and so on, in the 3D modeling of foam aluminum were solved. A foam aluminum model with porosity of 90% was obtained, and the connection between the model and finite element software was realized, which provided an effective numerical method for the foam aluminum model optimization and physical performance analysis. The foam aluminum sandwich plate model and foam aluminum composite material can be obtained through the application of the model, which can be used for computer simulation and related research work, such as automotive anti-collision beam, building materials, noise barrier plate. |
