A literature review on the planning and analysis of accelerated degradation testing for mechanical products

High reliability and long life are typical requirements for mechanical products. The performance requirements of mechanical products are increasing as science and technology develop, and the environment and working stress they bear are becoming more diverse. This issue has become one of the bottlenecks for mechanical products in lifespan and reliability generally. The aim of this study is to categorize, examine, and review the most applicable accelerated testing methods for mechanical products. The research status of accelerated modeling methods, statistical analysis, and design optimization of accelerated degradation testing(ADT) technology are reviewed. On the basis of literature analysis, the deficiencies and possible development directions of ADT were summarized and prospected. This work is anticipated to serve as a reference and provide important insights into the reliability of mechanical products.
