机构概念设计中功能自动分解的研究

THE STUDY OF FUNCTION DECOMPOSING FOR MECHANISM CONCEPTUAL DESIGN

设计模型的建立和功能分解理论是机构概念设计的关键。本文在用运动状态向量对机构模块进行程式化描述的基础上,提出了用基于矩阵初等变换的矩阵分解法进行机构功能的自动分解,由此建立了计算机能够识别的设计模型及功能分解的理论方法,为机构自动化概念设计提供了理论依据。

Building design model and a theory of function decomposing are the key for mechanism conceptual design. Based on formulation description mechanism module by motion state vector, the paper presents a method that motion function is decompose using matrix transformation. On the basis of that, a design model for presenting mechanical kinematic scheme and the method of function decomposing are established, which can be recognized by a computer. So theory foundation is built for mechanism automatization conceptual design.
