摘　　要：滚动轴承是大多数机械设备中工作条件最为恶劣的部件,它们在设备运行中起着承受载荷、传递载荷的作用,因而其运行状态直接影响到整台机器的性能。基于可拓学中的物元理论和可拓集合理论,首先建立了滚动轴承故障诊断的物元模型,然后通过引入关联函数,确切计算了待评轴承针对指定故障发生的程度,提出了一种诊断滚动轴承故障的新方法。Rolling bearing are always used in the worst condition in most mechanical machine. The matter element theory and the extenics theory were introduced.According to two theories, the matter model of rolling bearing fault diagnosis were established. The dependent degree of some lab samples were calculated based on the diagnosis rules of the trial rolling bearing. This model method can be used to describe the rolling fault condition into quantitative and can be a new method to diagnosis the fault of bearing and other equipment.
