【摘要】 概念设计是产品设计前期的关键，是决定产品市场竞争力的重要因素之一。随着全球化的进展，概念设计日益受到人们的重视。而随着计算机技术的发展，计算机辅助概念设计也日益成为研究的热点。然而，在目前的概念设计研究中却仍然缺少易于与计算机相结合的数学模型，这一问题也一直制约着概念设计自动化的实现。针对这一问题，为了提高概念设计的自动化程度，提出了功能向量编码方法。基于所提出的功能向量编码方法，对概念设计中存在的不足进行了研究：(1)研究了概念设计的求解方法，提出了机构分解与组合的变换原则，在引入补偿矩阵的基础上实现了矩阵分解与机构分解的结合。(2)在机构概念设计中引入了编码方法的思想，对机构信息进行二进制编译，得到了便于计算机处理的数据。(3)将功能向量编码方法应用于机构方案概念设计，建立了机构方案概念设计模型，研究了机构方案概念设计流程。(4)建立了机构功能载体库，基于功能向量编码方法开发了机构方案概念设计系统，并将功能向量编码方法应用于机构功能的提取和操作。(5)根据课题研究的需要，运用功能向量编码方法对胶印机中的典型机构进行了概念设计，得到了符合设计要求的方案解，验证了所提出的功能向量编码方法应用于机构方案概念设计是可行的，提高了机构方案概念设计的自动化程度。更多还原

【Abstract】 The conceptual design is the key at the earlier stage of the products design and is one of the important factors which decide the competition of the products in the market. Along with the progress of globalization, the conceptual design is valued by people day by day. And with the development of the computer science, the study of computer-aid conceptual design also becomes the hot spot gradually. However, in the current research of the conceptual design, it is still in need of mathematics model which combines with the computer easily, this problem has been restricting the realization of the conceptual design automation. Aiming at this problem, a functional vector coding method is put forward in order to improve the automation of mechanism scheme conceptual design. The paper researched the shortages existing in the conceptual design, based on the functional vector coding method that had been put forward.(1) The solution of the conceptual design was studied, the mechanism decomposing and constituting principle were put forward, the combination between matrix decomposing and mechanism decomposing was realized by utilizing the compensatory matrix.(2) The thought of coding method was utilized in the conceptual design, the mechanism information was translated and edited by means of the binary coding method, and the data has been gained and processed easily by a computer.(3)The functional vector coding method was applied into the mechanism scheme conceptual design, the mechanism scheme conceptual design model was built, the mechanism scheme conceptual design process was studied.(4) The mechanism function carrier database was built up, the mechanism scheme conceptual design system based on the functional vector coding method was developed, and the functional vector coding method was applied into the extracting and operating of the mechanism functions.(5)According to the need of the project, the typical mechanism of the printing machine using the functional vector coding method was conceptually designed, the scheme solution satisfying the design requirements has been achieved, and the functional vector coding method applied to the mechanism scheme conceptual design is feasible that, improves the automation of mechanism scheme conceptual design.更多还原
