Issues and Commentary on Mechanical Reliability Theories, Methods and Models

Abstract

Abstract: The status quo of reliability theory, viewpoints on reliability analysis and modeling, reliability evaluation methods and models, failure rate and life distribution are briefly reviewed. Commentaries are focused on the shape of failure rate curves and the related mechanisms to yield different shapes, the form of life distribution and influencing factors, the consistency of life distribution form and failure rate shape, the relationship between system reliability and component reliabilities, the mathematical meaning of stress-strength interference model and engineering background of application, the definitions on “importance” and “load severity” in reliability allocation technique.

Key words: reliability;life distribution;failure rate;stress-strength interference;reliability allocation
