Abstract
The drive shaft of the conveyor system of a car assembly shop is broken due to fatigue damage. The finite element theory and nCode fatigue life analysis software are used to analyze the fatigue life and fatigue damage of the drive shaft. Firstly, it uses Catia to build 3D models, imports the established drive axis model into ANSYS/Workbench, performs finite element static analysis, and then imports the analysis results into the fatigue analysis software of nCode. Fatigue life analysis is carried out, and the fatigue damage diagram and life diagram of the drive shaft of the conveyor system are obtained by the S-N analysis method of nCode Design-life. The most vulnerable position and life of the drive shaft of the conveyor system are found, and the method of improving service life of the conveyor system’s drive shaft is proposed.
