This dataset mainly includes data obtained from FMECA analysis during the reliability design process of the two-stage NGW planetary reducer system, results of reliability design requirement allocation, and results of optimal allocation of reliability improvement goals; data of gear pair fatigue damage models and life analysis under broadband non-Gaussian stochastic excitation; and data of reliability models for planetary reducer systems considering different failure correlations. Considering key critical components and their main failure modes, the top-down fault tree construction method is adopted to establish the fault tree of the planetary reducer system. Reliability models considering failure correlations are developed based on failure correlation mechanisms. Relevant simulation models are constructed based on the fatigue damage model and dynamic reliability of the reducer under broadband non-Gaussian stochastic loads. Following the US Military Standard "Environmental Engineering Considerations and Laboratory Tests", non-Gaussian stochastic loads are set as the input of the simulation models, and the measurement points specified in the standard are used as the data output points of the simulation models. Total data volume: 34.5 MB
