摘　　要：多面体空间结构是一种新型的空间结构类型,基于能够填充三维空间的多面体模型而构成。本文通过基于实体处理成型方法的分析,提出了一种基于数值计算的参数化成型方法,并且采用面向对象的高级计算机语言编程实现。该方法与通用的三维绘图软件或有限元分析软件相结合,能够用于不同基本单元和不同成型参数的多面体空间结构的成型建模,并且具有很高的成型效率。Polyhedron-base Structure, which consists of space-filling polyhedron models, is a new type of space structure. In this paper, on the basis of analyzing modeling method based on entity processing, a parameterized modeling method based on numerical computation is proposed, and developed by object-oriented programming. This method, combined with general 3D drawing software or finite element analysis software, is applicable for the modeling of Polyhedron-based Structures based on various fundamental units and having different parameters, and is of high efficiency to finish the modeling process.
