| 摘 要： | 空间热环境严重影响航天电子元器件的失效率，针对这一重要可靠性指标的计算问题，提出一种基于模糊逻辑的分析计算方法。该方法分析了温度、应力的大小及温度、形变的相对变化率对失效率的影响，有效解决了从定性分析到定量计算的过渡以及传统数学模型数据缺失等问题。本文研究为航天卫星电子元器件的可靠性分析提供有效的计算基础。

| Abstract: | The space thermal environment seriously affects the failure rate of aerospace electronic components. Aiming at the calculation of this important reliability index, a analysis method based on fuzzy logic is proposed in this paper.The method analyzes the influence of the temperature, stress and the relative change rate of the temperature and deformation on the failure rate, and effectively solves the problems of the transition from the qualitative analysis to the quantitative calculation and the missing of the traditional mathematical model. It provides an effective basis for the reliability analysis of space satellite electronic components. |
