ABSTRACT

The connecting rod is the main moving parts and an important component of engine. If the reliability is not strong enough, fatigue failure of the connecting rod would occur, thereby leading to component fracture and engine failure. So much so that connecting rod fracture. It will way to engine fault as well as serious outcome. In this paper, stress distribution and fatigue life of connecting rod in heavy vehicle engine were parametric model of Connecting rod is modeled using CATIA V5 R20 software and to that model, analysis is carried out by using ANSYS 11.0 Software. Finite element analysis of connecting rod is done by considering the materials of carbon steel. The results showed that the medial surface of small end will be the critical surface whereby damage will initiate at the maximum stretch condition. The critical location is at the transition area between the big end and connecting shank at maximum compression condition. In this paper, stress distribution and fatigue life of connecting rod in heavy vehicle engine were analyzed using the commercial 3D finite element software ANSYS.
