Tolerance design plays an important role in reliability design for electronic circuits. The traditional method only focuses on the consistency of output response. It is not able to meet the needs of increasing development of electronic products. This paper researches the state of related fields and proposes a method of multi-objective reliability tolerance design. The characteristics of output response and operating stresses on critical components are both defined as design objectives. Critical components and their operating stresses are determined by failure mode and effect analysis （FMEA） and fault tree analysis （FTA）. Sensitivity analysis is carried out to determine sensitive parameters that affect the design objectives significantly. Monte Carlo and worst-case analysis are utilized to explore the tolerance levels of sensitive parameters. Design of experiment and regression analysis are applied in this method. The optimal tolerance levels are selected in accord with a quality-cost model to improve consistency of output response and reduce failure rates of critical components synchronously. The application in light-emitting diode （LED） drivers indicates details and potential. It shows that the proposed method provides a more effective way to improve performance and reliability of electronic circuits.

As for aerospace electromagnetic relay （AEMR） which is of small batches and having difficulty in automatic production, the uncertainty phenomenon is remarkable due to excessive manual work involved in the assembly and adjustment processes. This kind of uncertainty may increase the coil voltage difference （CVD） caused by hesitate phenomenon in the pick up process of AEMR. Taking a certain type of AEMR for example, the CVD problem in the actual producing process has been studied in this paper. The primary cause of this issue, two-steps of armature motion （namely hesitate phenomenon） in the pick up process, has been found by analyzing the matching characteristics of electromagnetic and mechanical torques of AEMR. Through the optimization of the matching characteristics, the two-steps of armature motion problem is solved by robust design of the return reed which is a key part of AEMR. The validity of this research has been proved by the comparison of characteristics of AMER before and after the optimization.

以往性能可靠性的研究主要针对元器件或系统整体单独开展,缺乏将两者有效结合的研究方法,元器件厂家和用户的大量性能退化数据无法在系统早期设计中得到充分应用。为此,提出基于性能退化和电路仿真相结合的电子产品性能可靠性评估方法。首先根据电子系统原理建立电路仿真模型,再通过灵敏度分析确定导致系统性能参数变化的敏感元器件;之后,根据退化数据建立敏感元器件的性能参数退化模型,利用Monte-Carlo抽样和电路仿真获取系统性能参数的退化数据,进而实现性能可靠性评估。最后,以某型装备上的恒流电源为例具体说明实现过程,以验证该方法的有效性。

航天继电器作为一种密封的电器元件,其贮存可靠性对于导弹等武器装备至关重要。如何测试评价航天继电器在贮存过程中性能及可靠性的衰退,是继电器用户和厂家非常关心的问题。利用开发的实验系统对某型号航天继电器进行了贮存加速实验,得到了吸合时间的变化规律。分析并验证了贮存过程中吸合时间变化的主要原因是簧片应力松弛所导致的反力变化。通过仿真与实验均证实了吸合时间与簧片初力存在近似的线性关系,进而提出可采用吸合时间来表征簧片的应力松弛退化特性。建立了高温条件下继电器吸合时间的贮存退化模型,为进一步研究继电器贮存可靠性及贮存寿命预测奠定了基础。

电磁继电器触点的碰撞接触及所引起的回跳是影响继电器可靠性与电寿命的重要因素。传统的动态特性计算中,大多对此回避或仅作简化处理。本文提出了具有回跳特征的继电器动态反力计算模型。它通过分别建立衔铁与各触簧的动力学方程,将簧片结构等效为弹簧?振子模型,采用弹簧?阻尼模型计算连续接触力等方法得到动态反力特性。得到的动态反力特性包括触点间接触力、推杆接触力和各部件的运动速度及位移。经仿真与实验验证,使用该计算模型得到的结果是正确的。计算结果还表明,控制触点闭合速度、减小簧片刚度可以减小触点回跳、控制衔铁速度、增大动合超程及空程可以避免触点二次回跳。
