中文摘要：

在基于功能-行为-结构（FBS）的机械系统概念设计中，行为结构创新的计算机化推理具有重要意义．它在很大程度上决定了执行机构的数量和执行执行机构的输出运动．为了实现行为结构创新的计算机化推理，首先要定量化行为．从计算机辅助行为结构创新的角度，提出了行为结构创新假设，建立行为在行为集合内的表示方法、行为集合分组规则、行为分组法步骤、分组最优评价规则．并给出了实例分析．

英文摘要：

To serve the computer-aided conceptual design based on the function-behavior-structure （FBS） procedure, the computerized deduction of the behavior structure is studied in this paper. The behavior structure determines the quantity of the executive mechanisms, the output motions of and the relations among the executive mechanisms. For realizing the computerized deduction of the behavior structure innovation, behaviors has to be represented with quantity. Firstly, the presuppositions for the creative design of the behavior structure are presented. Secondly, the behavior representation within the behavior set, the rules for grouping the behavior set, the steps for the behavior grouping, and the evaluation of the behavior structures are studied. Finally, two examples are given to demonstrate the presented idea.
