摘要

目的研究可靠性强化试验技术在机载电子产品上的应用,为提升机载电子产品可靠性水平提供工程实践支撑。方法选取高故障机载电子产品,通过应用可靠性强化试验原理、基本实施流程及试验方法,开展远超设计要求和规范的低温步进、高温步进、快速温变、振动及综合应力试验,主动激发产品缺陷并迭代改进。结果通过低温、振动、快速温变及综合应力试验,发现选用的高故障率机载电子产品在器材选用、电路设计、强度设计及工艺可靠性方面均存在不足,通过制定整改措施,进一步改进设计,产品固有可靠性得到提升。结论通过对比改进前后可靠性强化试验结果,发现选用的高故障率机载电子产品可靠性水平提升约1.6倍,产品工作极限温度范围和抗振能力均得到显著提升,环境适应性显著增强。这也说明可靠性强化试验对于缺陷暴露和产品优化具有较强的工程应用价值。

Abstract

The work aims to study the application of reliability enhancement testing technology in airborne electronic products to provide engineering practice support for improving the reliability level of airborne electronic products. By selecting high-failure airborne electronic products, and through the brief introduction of the principle, the basic flow and test methods of reliability enhancement testing, low-temperature stepping, high-temperature stepping, rapid temperature change, vibration and comprehensive stress tests far exceeding design requirements and specifications were carried out to actively trigger product defects and iteratively improve them. Through experiments, it was found that high-failure airborne electronic products had deficiencies in terms of equipment selection, circuit design, strength design and process reliability. By formulating rectification measures and further improving the design, the products passed the tests without faults, and the inherent reliability of the products was enhanced. Through the comparison of test results, it is found that the reliability level of high-failure airborne electronic products is increased by approximately 160%, the working limit temperature, vibration resistance and environmental suitability of the products are improved and enhanced significantly. This further demonstrates that reliability enhancement testing has significant engineering value in defect identification and product optimization.
