Description
Summary:This paper introduced the good characteristic of rank-order morphological filter and its application in vibration signal de-noising. At first, the definition of rank-order morphological filter was introduced. Then, the combined filters were constructed by the rank-order opening and rank-order closing. At last, the interrupted vibration signal was de-noised by the combined rank-order morphological filters. Practical and simulation results show that this method has better de-noising effectiveness. It's suitable for on-line monitoring and diagnosis of rotating machinery.
