| 摘 要： | 根据耗损失效产品的渐发性故障模型,应用稳定磨损阶段的理论,提出了一种延拓试验方法。该方法将产品关键摩擦副的磨损寿命作为产品的使用寿命,在失效模式和机理不变的情况下,既不需要试验样品做到失效,又缩短了试验时间,延拓预测产品寿命特征值。

| Abstract: | Based on the gradually appeared failure model of wear-out failure,an extended test method is developed with the help of the stable wear stage theory.The method regards the wear life of main friction pair as the useful life of a product.On the condition of the failure mode and mechanism being unchanged,the method can be used to predict life characteristic value.Meanwhile,the samples are not needed to be tested until failure and the test time is reduced as well. |
