摘要:

针对目前强化试验剖面效率低、成本高的问题, 提出了某型弹类电子产品温度强化试验剖面设计框架。结合产品可靠性框图对试验对象进行失效逻辑分析, 基于元器件降额的步长设计方法(step design method based on component derating, CD-SDM)优化步长、缩短试验时间, 采用基于有限元仿真的确定性分析方法获得工作极限和破坏极限估值, 降低步长划分时极限间工作裕度的影响, 实现步长、试验时间和其他要素的优化。以某型弹类电子产品高温步进为例验证所提方法, 结果表明获得的温度强化试验剖面较传统方法在试验时间上最少可缩短13.33%左右, 与传统方法相比减少了1/4的检测次数, 优化了目前可靠性强化试验剖面设计对弹类电子产品试验效率低、成本高的问题。

Abstract:

Aiming at the problems of low efficiency and high cost of the enhanced test profile, a design framework for the temperature enhancement test profile of a certain missile electronics is proposed. Combined with the product reliability block diagram, the failure logic analysis of the test object is carried out. The step design method based on component derating (CD-SDM) optimizes the step size and shortens the test time, and the deterministic analysis method based on finite element simulation is used to obtain the working limit and the failure limit estimation, which reduce the influence of the working margin between the limits when the step size is divided and realize the optimization of step size, test time and other elements. Taking a high-temperature stepping test of a certain missile electronics as an example to verify the proposed method, the experimental results show that the temperature strengthening test profile obtained can be shortened by at least 13.33% in test time compared with the traditional methods, and the number of detection times is reduced by 1/4 compared with the traditional methods, which optimizes the problem of low efficiency and high cost of the current reliability enhancement test profile design for missile electronics.

Key words: reliability enhancement testing, derating design, test profile, thermal simulation, missile electronics
