Mixed uncertainty analysis for dynamic reliability of mechanical structures considering residual strength
Reliability Engineering & System Safety(2021)
Abstract
•A mixed uncertain model is established based on fuzzy, random and interval parameters.•A dynamic reliability model with mixed uncertain parameters is proposed.•Based on entropy equality information, random and fuzzy variables are transformed.•Probability and interval analysis are adopted to evaluate dynamic reliability index.
