摘要
开发了具有数据采集、导出及处理功能的加速退化机理一致性判别试验测试系统。针对某型电阻器,以试验经费为限制条件、以提高加速退化模型参数估计准确度为目的,对加速退化机理一致性判别试验的样品量、试验时长进行优化,进而给出试验方案。根据所需测试的参数,设计实现了试验测试系统的软件和硬件部分。该系统具有测试精度高、自动化程度高、可测样品数量大、可测器件种类多等特点,为失效机理一致性分析及可靠性评估提供了数据基础。
An accelerated degradation mechanism consistency discriminant test system with data acquisition,derivation and manage functions was developed.For a certain type of resistor,firstly,the test cost is used as a limiting condition to improve the accuracy of accelerated degradation model parameter estimation.The sample amount and test time of the accelerated degradation mechanism consistency discriminant test are optimized,and then the test plan is given.According to the parameters of the required test,the software and hardware parts of the test measurement system are designed and developed.The system has the characteristics of high test accuracy,high degree of automation,large number of measurable samples,and many kinds of measurable devices,so that it provides a data foundation for failure mechanism consistency analysis and reliability assessment.
