中文摘要：

废旧零部件是否具有剩余使用寿命决定了其再利用的潜力。为了准确评估废旧零部件的剩余使用寿命,建立了一种废旧零部件剩余使用寿命评估模型。以零部件失效数据和历史服役工况数据为基础,联合威布尔分布和多元回归分析模型来实现剩余使用寿命的评估。以机床电机为例,验证了上述模型的可行性。

英文摘要：

Whether the used parts have remaining useful life determines the reuse potential.A remaining useful life estimation model for used parts was proposed in order to accurately assess the remaining useful life of used parts.Based on the failure data and history floor data of used parts,Weibull distribution and multiple regression analysis model were integrated to assess the remaining use-ful life.A machine tool motor was taken as an example to illustrate the feasibility of the decision model.
