Finite Element Method Simulation and Multifactor Failure Analysis of an Important Stepped Shaft Fracture Events



ABAQUS finite element method was used to simulate and analyze a fracture event of an important stepped shaft parts. The results show that the stress concentration is serious at the step where shaft fracture occurs. The maximum stress occurs at the R2 transition corner and the value under the most unfavorable condition is 319.9MPa, which exceeds the yield strength limit of the material. SEM and X-ray analysis, design analysis, machining quality analysis and Heat Treatment process quality analysis show that fracture of the shaft is a fatigue fracture initiated by multiple sources, and the initiation is mainly related to the small turning radius of the step. The rough surface with micro-defects may be the origin of fatigue crack initiation, and the improper control of the quenching and tempering process has a negative impact on the initiation of the crack.

Host city and venue

Vienna (Wien) is the federal capital and largest city of Austria, and one of the nine states of Austria. Vienna is Austria's primate city, with a population of about 1.9 million (2.6 million within the metropolitan area, nearly one third of Austria's population), and its cultural, economic, and political centre. It is the 7th-largest city by population within city limits in the European Union.  Read more...
