摘要

Accelerated life testing can be operated in the designing process of a product to predict the lifetime of the product. The design of the product would be improved if the lifetime prediction value is not acceptable. This paper presents a method to predict lifetime of products based on proportional hazards-proportional odds model in accelerated life testing. Proportional hazards-proportional odds model makes proportional hazards model and proportional odds model special cases of it through transformation parameter. A testing system is established to process constant stress accelerated life testing for miniature bulbs under high stress levels and failure time data of the bulbs under each stress level are analyzed using proportional hazards-proportional odds model. Lifetime prediction of the miniature bulbs is presented finally.
