Aiming at the problem of performance degradation of the cut-off part of coal mining machine,a performance degradation detection method of the cut-off part of coal mining machine is introduced by taking MG300/720-AWD coal mining machine as an example.The method is mainly through the collection and pre-processing of coal mining machine electrical,temperature,efficiency,speed,pressure,vibration and other aspects of the indicators of the data collection and pre-processing,the use of benchmark Gaussian mixture model for calculation and analysis,in order to deduce the entropy value to measure the degree of degradation of the performance of the cutting part of the equipment,and then to determine the development trend of equipment degradation,to provide support for the cutting part of the maintenance and repair,to confirm that the method has a certain value of practical application.
