Abstract: Abstract: The urgency of the discussed issue. This article attempts to summarize research results in the analysis of vibration parameters of jaw crushers and to create a reserve for the development of common diagnostic criteria suitable for assessing and implementing short-term forecasting of degradation of the technical condition of diagnosed technological equipment.
The main aim of the study: Create a classification of diagnostic signs of defects development in the diagnosed equipment suitable for improving the existing methodologies for normalizing vibration and creating algorithms for common diagnostic criteria for assessing the actual state of crushing equipment by vibration parameters.
The methods used in the study: As part of the work, the results of an integrated diagnostic approach were used, which included spectral analysis, envelope analysis, analysis of the acceleration / stick-out characteristics, and analysis of the temporal implementation of the signal. It is shown that the results of the integrated approach allow us to identify a clear associative relationship between the parameters of the vibration signal and the presence of damage in cases of implicit diagnostic results.
The results: The results obtained prove the fundamental effectiveness of the proposed methodological approach for analyzing the parameters of vibration generated during the operation of jaw crushers. The practical use of the developed common diagnostic criteria will open an innovative way for the introduction of a maintenance system for equipment at the coal enterprises of Kuzbass in accordance with its actual state.
