Fatigue Life Reliability Analysis of Belt Conveyor Driving Drums Based on FEM
Conveyer system security and reliability are related to belt conveyor drum design level .This paper proposes a method of analyzing the belt conveyer drum fatigue life reliability based on FEM, and establishes a real-time dynamic loading model, which can reflect accurately the condition of drum actual work load. This method realize drums fatigue life reliability analysis by applying rain-flow count method for processing stress spectrum that are obtained from FEM, it combines material P-S-N curves and other performance parameters and adopts Miner ruler. By applying the method on a practical project, the results indicate that the method is correct and practical. It poses the ability of avoiding the blindness in the drum structure size design, and it has the vital significance of raising drum design level.
