Fracture Reason Analysis of Coal Compactor Roller Shaft

Abstract

The cause of the fatigue fracture of the coal compactor roller shaft is analyzed in this paper. By means of investigating the macro-fracture and micro-fracture analysis for the shaft roller, and use ANSYS software to simulate the fatigue stress to find out the reasons of the roller shaft fracture and thus provides theoretical support for further optimizing the design of the roller shaft structure.This lied a solid foundation for how to improve the designation of roller shaft and how to improve the lifespan of the roller shaft
