基于全关联矩阵的可变功能机械功能耦合分析

o assist design analysis of the adaptable-function machines, this paper first proposed a few concepts including direct association, indirect association and complete association between function and components, and built the direct incidence matrix between functions and components. It then quantitatively described the indirect coupling value using the propagation of design change possibility about the parts; thereby the complete incidence matrix was generated. Based on this, it proposed the concept of function coupling degree, built the function coupling matrix, and then used comprehensive coupling degree to evaluate the structural compactness of the adaptable-function machines. And analyzed the influence from the components to functions, in order to provide the quantitative foundation for the design analysis of those machines. Finally a case study of the multi-function pliers explained the feasibility of the proposed methods and their meaning. ???
