概念结构设计过程中功能表面重构技术研究

在基于功能表面分解重构原理的生长型设计过程中，产品概念结构中功能表面的重构即功能表面的类型、数量及其相互炎系的选择与确定直接决定了零件的概念结构，并且从概念上基本确定了后续结构能否经济制造的空间约束。由于相关知识支持技术的缺乏，仍需要设计人员靠经验决定，降低了生长型设计的效率。文章分析了功能表面间的位置关系、联接方式的含义及其可制造性评价，与实际工艺技术知识相联系，提出了功能表面之间空间位置关系和联接方式的并行确定方法，开发了基于知识的设计支持模块，促进概念结构生长式设计效率的进一步提高。

Study on the Reconstitution of Function Surface in the Process of Growth Design

In the process of growth design based on the decomposition and reconstitution of function surface, the reconstitution of function surface, i. e. determining the number, the style and the relationship of function surface is the key of conceptual structure. It is the constraint of the manufacturability of the structures. It is the barrier to improving the efficiency of the growth design due to the lack of the related knowledge. The position relationship, the connection mode and manufacturability of function surface are analyzed comprehensively in this paper. And the methodology of determining the position relationship and connection mode concurrently according to the actual technical knowledge is proposed. A design module is developed based on knowledge, which can improve the efficiency of growth design process.
