Journal of Failure Analysis and Prevention Aims and scope Submit manuscript

Abstract

To investigate the strength and fatigue life of a fracture-split connecting rod, this study combines experiments on connecting rod fracture splitting, three-dimensional reconstruction technology and the finite element technique. An actual fracture joint surface of a connecting rod is obtained by fracture-splitting experiment, and its mode is reconstructed by reverse engineering. Subsequently, the reconstructed fracture plane is imported into CAD to establish the actual three-dimensional model of the fracture-split connecting rod. The fatigue characteristics parameters of the fracture-split connecting rod material, namely C70S6, are obtained by a rotating bending fatigue test. Finally, by comparing to a traditional machining connecting rod, the inspection of the fatigue life of the fracture-splitting connecting rod is performed using the finite element method and the fatigue analysis theory. The results show that the fracture-split connecting rod meets the strength and fatigue life requirements.
