复杂仿生结构设计中的CAD/CAE技术应用

The Application of Advanced CAD/CAE Technologies in the Design of Complex Biomimetic Constructions

大型复杂仿生建筑的结构设计相当复杂,先进CAD/CAE技术逐步应用到建筑工程领域,对于复杂仿生结构设计中难题的解决方案具有独特的优势。本文在上海喜玛拉雅项目当代艺术中心的结构设计中广泛采用虚拟仿真技术,利用CATIA建立三维复杂曲面模型,使用HYPERMESH进行网格离散,然后导入到ANSYS/SAP/ABAQUS中进行不同需求的结构分析,较好地完成了结构设计,对类似的复杂仿生结构设计具有重要的参考意义。

Large and complex biomimetic structures are very difficult to design.Advance CAD/CAE technologies are gradually applied to the construction field and provide a useful solution for the structural design of biomimetic constructions.The technologies of virtual simulation were extensively used in the project of Himalayan Art Center in Shanghai,which is very complex biomimetic structure.CATIA was used to accurately build up the complex curved surfaces.The grid model was generated by HYPERMESH and inputed into ANSYS/SAP/ABAQUS to carry out the different analysis for different purposes.The structural design was completed very well.The solution could be the reference for the same kinds of biomimetic construction.
