Development of Condition Monitoring of Industrial Machines using Strain Gauge Analysis and Locating Defects via Pulse Control

The paper reviews application of real-time strain gauge analysis for locating defects via pulse control. Various diagnostics and defect detection methods used for condition monitoring have advantages and disadvantages. In this study, we suggest pulse control and high-frequency data collection from strain gauge sensors. A pulse source located in space allows splitting a complex spectrum, produced by a number of defects, into a set of simple spectra for each defect. It gives a more efficient analysis. The paper presents the concept of locating defects using strain gauge control and pulse control together with an experimental study. According to the study, a sequence of hits was made on a surface of the experimental equipment assembly. Then location of a hit was calculated according to the proposed method using experimental electronics. The results show low error for position locating.
