航天产品加速寿命试验一般都采用高温应力,加速模型应用阿伦尼斯模型。但除了受高温影响之外,星上产品在轨还长期受到温度循环应力的作用。目前国内航天产品开展温度循环应力加速寿命试验缺乏相关理论模型支持,本文针对温度循环加速寿命模型和试验设计开展了研究,可为星上产品开展温度循环加速寿命试验提供理论支持。 Accelerated life tests of aerospace products generally use high temperature stress, accelerated model application Arrhenius model. But in addition to being affected by high temperatures, on-orbit products are also subject to long-term temperature cycling stress. At present, the research on temperature cycle accelerated life model and experimental design is carried out in this paper, which can provide theoretical support for the temperature cycle accelerated life test of products on the satellite.
