Abstract

The invention, which belongs to the technical field of mechanical equipment, relates to a method and device for predicting the fatigue failure of a drive shaft of a horizontal conveying device. According to the method, stress data of a drive shaft are collected periodically by a sensor based on the actual working condition of the drive shaft; whether the stress data collected in each period exceeda preset range is determined; if so, damge values are accumulated; and then when the accumulated damage value is determined to reach a threshold value, warning sent out. Therefore, on the basis of sensor information acquisition, big data modeling and data calculation, a fatigue failure prediction model of a drive shaft is established; and thus the service life is predicted based on the actual operating condition, so that the accuracy and convenience of the prediction are improved substantially. Moreover, the method and device for predicting the fatigue failure of a drive shaft of a horizontalconveying device have advantages of simple implementation, low cost, and wide application range.

Description

technical field

[0001] The present invention relates to the technical field of mechanical equipment, in particular to the technical field of data analysis of mechanical equipment, in particular to a method and device for predicting fatigue failure of drive shafts of horizontal conveying equipment. Background technique

[0002] At present, in the automobile manufacturing industry, the rolling bed is a common horizontal conveying equipment. When the drive shaft of the roller bed gradually wears out until it breaks under the action of fatigue load, it will not only cause the failure of a single piece of equipment, but also cause the production interruption of the production line. In a production system, the inability to accurately assess the damage state of a drive shaft often leads to huge losses. Therefore, the development of a fatigue failure prediction model for drive shafts can effectively avoid abnormal shutdown of equipment, reduce maintenance costs, and improve economi...
