The invention discloses an environmental stress screening test and forecasting repair comprehensive optimizing method, which comprises a planning stage and an executing stage; the planning stage includes three steps which are environmental stress screening test modeling for many times, repair element confirming module and environment stress screening test, and preventive repair planning comprehensive optimization; the executing stage includes the implementation of environmental stress screening test and the predicting repair planning and execution. The method comprehensively considers the environment stress screening effect and the screening cost before the product is put into use, and the influence of the selection of the repair time on the repair cost after the product is put into use; before the product is put into use, the environmental stress condition and the test frequency are comprehensively optimized and selected on the basis of the environmental stress screening test model and the forecasting repair planning model; after putting the product into use, the preventive repair time of is optimized according to the state monitoring data of every product in use after the productis put into use; the method can effectively reduce the total cost of screening and repair.

Environmental stress screening test and forecasting repair comprehensive optimizing method

The invention relates to a dynamic stress accelerated life test profile compilation method. The method comprises the following steps that 1, on the basis of a damage equivalent principle, dynamic stress is converted into static stress within a certain time interval; 2, on the basis of the step 1, an equivalent relation of a dynamic stress accelerated factor and a static stress accelerated factor is obtained; 3, the dynamic temperature stress is adopted as the dynamic stress, and on the basis of an Arrhenius model, dynamic temperature accelerated stress accelerated factor computational formulais obtained; 4, the dynamic temperature accelerated stress profile is compiled, and three parameters including a dynamic temperature accelerated stress mean value Tm*, a dynamic temperature accelerated stress amplitude Ta* and a dynamic temperature accelerated stress cycle period w* are determined. According to the method, the dynamic stress accelerated life test profile can be designed accordingto the dynamic change environment actually adopted by products, the reality degree simulated by the environment conditions in the accelerated test is improved, and it is ensured that the product failure mechanism in the test is consistent to that under the actual service condition.
