| 中文摘要: |
| 针对惯性器件贮存寿命评估方法，总结了自然贮存试验评估方法其贮存数据应具备的特点、寿命分布，分析了加速贮存试验评估方法通过预实验确定加速应力类型与范围的必要性，介绍了建立惯性器件寿命分布模型、加速寿命模型、性能退化模型的常用方法，总结探讨了现阶段贮存寿命评估的失效判据、试验时间、测试周期等具体试验方案。调研结果表明，惯性传感器贮存寿命评估多采用加速贮存试验评估，其寿命多符合威布尔分布，采用温度作为加速应力时多采用阿伦尼斯模型作为加速模型，开展试验时多采用步加温度应力、定时截尾方式，对开展惯性器件贮存寿命试验具有一定参考意义。 |
| 英文摘要: |
| The characteristics and lifespan distribution of storage data that should be possessed by natural storage test evaluation methods were summarized. The necessity of determining the type and range of accelerated stress by pre-experiment and the common methods of establishing the life distribution model, accelerated life model and performance degradation model of inertial devices was analyzed. Specific experimental schemes such as failure criteria, test time, and test cycle for current storage life evaluation were summarized and discussed. The results indicated that the evaluation of the storage life of inertial sensors was usually carried out through accelerated storage testing, which usually followed a Weibull distribution. When using temperature as the acceleration stress, the Arrhenius model was usually used as the acceleration model. When conducting experiments, the stepwise temperature stress and timed truncation method were usually used, which had certain reference significance for conducting storage life tests of inertial devices. |
