Diagnostics of Industrial Equipment by Locating and Identification of Defects Via Remote Strain Gauge Analysis

The paper is dedicated to theoretical and instrumental basement for diagnostics of industrial equipment by locating and identification of defects via remote strain gauge analysis. Various methods of diagnostics of industrial equipment are analyzed from a view point of their objectivity, reliability and ability for automation. It is established that all observed methods in reality are indirect; hence, initial data for analysis has some bias. The solution of this problem is based on the idea to use a remote strain gauge analysis, that means to analyze dynamic force in detail. The equipment is usually made of steel, so the equipment may be considered as an absolutely rigid body. Hence, the dynamic force from oscillating defects and parts is completely and without loss transferred to equipment supports and strain gauges. According to the developed mathematical model is possible to identify the position of source of disturbing force, i.e. to get its real position. Also, instrumental basement is analyzed and prepared for implementing a methodology of locating and identifying defects of industrial equipment.
