Journal Title: Вестник научного центра по безопасности работ в угольной промышленности - Year 2018, Vol 0, Issue 4
Abstract
This paper considers the results of work to provide the prerequisites for creating a group of common diagnostic criteria suitable for performing an assessment of the actual state and predicting the process of electric and diesel-hydraulic drilling rigs equipment degradation. The work aim was development of an algorithm for creating common evaluation criteria for analyzing the parameters of mechanical vibrations generated during operation of power-mechanical equipment of drilling rigs and also defects classification by types, causes and hazard levels and to formalize diagnostic features for convenience in their use when developing a code for an automated control algorithm for the technical condition of drilling equipment based on frequency types of diagnostic features. In addition, the study proves the expediency of using adaptive short-term models in the conditions of technological equipment operating at the coal industry enterprises planned repairs system.The paper substantiates a comprehensive approach to the vibration parameters analysis of the power-mechanical equipment of mining machines, including the results of spectral analysis, envelope analysis, wavelet transform, and run-out characteristics analysis. It is shown that only in condition of a comprehensive approach to diagnostics methods wide opportunities open for timely diagnosis of mining machine equipment defects, including those at the stage of origination. The results indicate the proposed approach effectiveness for solving the problem of developing common criteria for assessing the complex mechanical systems technical condition, with which you can predict changes in the actual state of drilling machines and drilling rigs equipment.
