摘　　要：如何建立具有合理受力性能的自由曲面空间结构是设计过程中需要重点考虑的关键问题。以结构形态学观点为指导,将曲面几何形状的建立与寻找曲面合理受力性能的方法相结合,这一过程称为曲面的形态创建。本文对结构形态学所涉及的若干概念进行了阐述,并对自由曲面空间结构形态创建过程中所存在的关键技术问题进行了探讨。这些关键问题包括:(1)自由曲面结构的生成方法;(2)结构合理受力性能的评价指标及指标之间的相互关系;(3)合理曲面的创建方法等。通过对这些问题的探讨试图为自由曲面的研究与应用提供若干建议。One of the most important problems in the design procedure of space structures is how to get rational shapes of freeform surfaces. Based on the concept of structural morphology, the fabrication of freeform surfaces can be combined to the method of pursuing optimal structures with rational mechanical performance, which can be defined as computational morphogenesis. In this paper,some concepts of structural morphology are introduced and some key problems are discussed simultaneously.The key problems can be abstracted as follows:Firstly,how to fabricate freeform surfaces?Secondly,what kind of generating methods are feasible for rational freeform structures. By discussing the questions above,some advices are proposed finally.
