This paper introduces the inverse spectrum and its features ,and presents with some applied experimental examples in the rolling bearing analysis by using this method. The analysis indicates that the inverse spectrum has a noticeable feature to distinguish the influence of the side frequency as well as the transfer function in measuring test system. Based on the features of the test vibration signal of the rolling bearing in the different faults as well as the spectrum diagram,the position of the bearing fault in a complex disturbing sign can also be accurately located.
