中文摘要：

在机电一体化系统概念设计过程中，功能结构的生成和功能求解是交替进行、互为因果的关系。基于这一实际，提出了一种基于功能→效应→作用原理→结构方案映射的机电一体化系统概念设计反馈循环求解模型。分析了单一功能与机电系统功能的各自求解进程，研究了接口匹配及功能求解等反馈循环求解的关键实现技术，开发了一个机电系统概念设计自动化原型系统，并以电脑绣花机的概念设计为例进行了验证。

英文摘要：

Due to the fact that function structure generation and function solving were alternative processes with mutual causality during conceptual design phase of mechatronic system, a conceptual design cyclic feedback solving model of mechatronic system was put forward based on mappings among function layer, effect layer, working principle layer and structure layer. The solving processes of single function and system function were analyzed respectively. Then key enabling technologies of interface matching and function solving were studied. Finally, a computer- aided conceptual design automatic software prototype system for mechatronic systems was developed and the conceptual design of computerized embroidery machine was given as an example.
