Abstract:In order to solve the problems of complex product life prediction in multi-stress accelerated life test and the difficulty of establishing a composite acceleration model, a life prediction method under multi-environmental stress accelerated life test is proposed. According to the multi-stress acceleration model of the general logarithmic linear model, the distribution data of the multi-stress acceleration test is used to verify the distribution of the data. The failure data of the stress level is used to estimate the Weibull distribution parameters. Make predictions and verify the evaluation results. Evaluation results show that the method has high prediction accuracy and is a feasible method for product life prediction under multiple accelerated stress conditions.
