通过恒定应力环境下的继电器加速贮存寿命试验,采集关键参数,引入移动标准差的概念,结合最小二乘多项式拟合,建立了单个继电器贮存寿命预测模型。通过实例分析,验证了预测模型的有效性,提供了一种快速预估产品贮存寿命的方案。
The key parameters are gathered through the accelerated life testing( ALT) under constant stress.Mobile standard deviation is applied to the storage life prediction model of a single relay using the least squares polynomial fitting. The example analysis verified its validity and it provides a new route for efficient life estimation.
