轴承异常的逐次模糊诊断

Sequential Fuzzy Diagnosis Method and the Application to Ball Bearing

采用逐次模糊诊断法时 ,首先找出能识别异常的特征参数 ,然后逐次进行模糊推论 ,诊断出正常或异常状况。以NU312轴承为例。介绍了诊断外圈、内圈和滚动体缺陷的方法。附图

When developing a fuzzy diagnosis system for machinery condition diagnosis, fuzzy relation between failure symptoms and failure categories must be defined for fuzzy interference. Sequential fuzzy diagnosis was proposed. As a application example, the diagnosis of inner ring,outer ring and rolling elements was introuduced.
