Abstract

  At present, the FMEA (Failure Mode and Effect Analysis) for electromechanical products is cumbersome, time-consuming, and error-prone. The analysis objects of this method also cannot reflect the characteristics of “motion determines function” in electromechanical products. In order to address such problems, firstly, according to the decomposition idea of “function-motion-action”，the function of electromechanical products is decomposed into the most basic action (that is, meta-action); secondly, the characteristics of meta-action are analyzed, and the rationality of taking meta-action as the research object of electromechanical products FMEA is discussed; thirdly, based on those above, a M-FMEA (Meta-action Failure Mode and Effect Analysis) method for electromechanical products is proposed; finally, traditional methods and the proposed method are compared in rationality, applicability and simplicity, which highlights the advantages of the proposed method. A numerical control machine tool made in China is taken as an example, the applicability and effectiveness of the proposed method are verified, and the accuracy and efficiency of failure analysis for electromechanical products are also improved.
