Vibration analysis of electromechanical equipment of mining shovels

Abstract

Some results of the scientific study into methodological approaches to development of a group of common diagnostic criteria suitable for the assessment of actual state of electromechanical equipment of electric mining shovels are presented. One of the objectives of this scientific research is to prove feasibility of implementing short-term degradation models in the framework of the preventative maintenance system. The second target is to develop a methodology for creating an algorithm of a common diagnostic criterion suitable for identifying and assessing risk of defects in equipment of mining machines. It is shown that the comprehensive approach to diagnostics based on vibration parameters opens wide opportunities for timely detection of defects in equipment of mining machines, including those at the stage of initiation. Implementation of this study results and the use of the developed criteria will improve management efficiency of maintenance of mining equipment and minimize probability of failure of electric shovel equipment.
