Research on meta‐action decomposition and meta‐action unit modeling technology for electromechanical product

Abstract

AbstractThe current decomposition methods are not suitable for electromechanical product; the smallest decomposition units obtained by these methods are static parts or components, which cannot reflect the characteristics of electromechanical product that ‘action determines motion, and motion determines function'. Meta‐action is the smallest action to realize the function of electromechanical product, and it is reasonable to regard meta‐action as the smallest decomposition unit of electromechanical product. Meta‐action unit is the smallest structural unit to ensure the normal operation of meta‐action, and it is also the smallest carrier of electromechanical product quality characteristics. Meta‐action unit modeling technology is the basis of other subsequent research, so it is necessary to study it. In this paper, detailed criteria for meta‐action decomposition and meta‐action unit separation are formulated, and the standardized structural model, symbolized conceptual model, and assembly model of meta‐action unit are also studied, which provide a basis for mechanical, kinematic, and failure mechanism research of electromechanical product. A CNC (computer numerical control) machine tool made in China is taken as an example for meta‐motion decomposition and meta‐action unit modeling, and the results verify the applicability and correctness of the method proposed in this paper. The proposed method is also applicable to other types of electromechanical product.
