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

The 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.
