Research on the reliability of the drive motor of the scraper conveyor

Based on Weibull Distribution and gray prediction model, the reliability analysis of the drive motor of the power part of the scraper conveyor is carried out. Firstly, the Weibull Distribution position parameter is introduced to determine the time when the drive motor enters the loss period, and then the gray prediction model is used to solve the parameter estimation problem of the three parameters of Weibull Distribution, and finally the average life of the motor is obtained through simulation analysis, and it is proved that the accuracy of the prediction results can be guaranteed when there liability analysis is carried out by using this method.
