Recent trend in condition monitoring for equipment fault diagnosis

摘要

This article intends to unveil the recent trend of research work with proper justification and surveying in the field of condition monitoring and fault diagnosis. For attaining such results, a total of 177 articles from 57 journals are reviewed in this article. Condition monitoring is a procedure in predictive maintenance which deals with preventing an impending failure. This provides the manufacturing unit with the capability for improved production rate by obviating the downtime and in reducing maintenance and operation cost. Many types of errors or defects can occur in different equipments while the plant is in operation. Therefore, it is essential to track continuously the pattern of errors or changes in certain parameters like voltage, current, pressure, flow, strain, vibration, temperature, etc. The greatest advantage of fault diagnosing or condition monitoring is that it alerts the operator about the impending failure after detecting the changes in the respective parameters. Fault patterns and diagnosis of several equipments and machineries have been reported in the literature and this review systematically presents their classification under multiple categories.
