| This paper intends to study an accelerated life test method for shipborne missile board computer under the multi-stress of land environment and ship environment, which can describe the environmental stress of products under the comprehensive environment more representatively and authentically , and thus lay a foundation for converting the environmental stress profile into the accelerated stress profile as accurately as possible. Through the accelerated life test, the product storage life is accelerated to the target lifetime to verify and evaluate the residual storage life of products. According to shipboard working environment, and starting from the sea state of the ship carrying the research object, the vibration stress of the ship is determined by the corresponding relationship between the sea state and the vibration magnitude of the ship. Considering other stresses under the comprehensive environment, an accelerated test method combining temperature-vibration-electrical stress and other environmental conditions is developed. Taking the shipborne missile board computers that have reached the designed storage life as the test objects to carry out a comprehensive accelerated life test of temperature-vibration-electrical stress. By using the accelerated life test method combining temperature-vibration-electric stress, it was verified and evaluated that the residual storage life of shipborne computers could be extended to target lifetime, and good test results were obtained.According to the influence of ship working environment on storage life, the study on vibration acceleration test of ship achieves a life evaluation result which is more suitable for the actual life, providing a reliable basis for the follow-up life extension research. |
