Research on Model and Application of Elevator Safety Remaining Service Life
In view of the lack of maintenance of elevators in China, this paper builds a statistical model of elevators’ remaining service life based on elevator operation and maintenance management data, plots the remaining service life curve of elevators, and implements the prediction of preventive maintenance intervals from time to time and scrap time (i.e., the safety remaining service life) for elevators, and verifies the reliability of the model through empirical analysis.
