Reliability Analysis of Meta-action Unit in Complex Products by GO Method

The stability and reliability of meta-action unit is the basis for ensuring the reliability of the whole machine. Based on the analysis of the structure of meta-action units, a fishbone diagram of influencing factors of meta-action unit reliability is established. Then, the GO method is used to analyze the reliability of the meta action unit, and the universal GO diagram model and probabilistic model of the unit action reliability are established. Taking the reliability analysis of spindle rotation element motion as an example, the application of the proposed method is verified.
