Abstract

Reliable condition monitoring (CM) highly relies on the correctness of fault-related features extraction from CM signals. The conventional EWT adopts default method to pre-define values for both mode number and mode boundaries in spectrum. It is not adaptive to the signals being inspected. As a consequence, it would lead to inaccurate feature extraction thus unreliable WT CM result sometimes. For this reason, an improved EWT method is investigated in this paper to precisely extract features. The main contribution of this paper focuses on the development of data-driven adaptive spectrum segment method to perform improved EWT. The experiments have shown that thanks to the use of optimization algorithm, the fault-related features buried in WT CM signals have been extracted out successfully.
