Fatigue and Structural Analysis of Connecting Rod’s Material Due to (C.I) Using FEA
Journal Title: International Journal of Automotive Engineering and Technologies - Year 2015, Vol 4, Issue 4
Abstract
In this research connecting rod is one of the most important part in engine assembly which transfers energy from piston to crankshaft and convert the linear, reciprocating motion of a piston into the rotary motion of a crankshaft. The connecting rod primarily undergoes tensile and compressive loading under engine cyclic process. The forces acting on connecting rod are:- forces due to maximum combustion pressure and force due to inertia of connecting rod and reciprocating mass[1]. From the viewpoint of functionality, connecting rods must have the highest possible rigidity at the lowest weight. This research addresses the computation of the strength and distortion characteristics of a connecting rod. Finite element method is used to analyze the connecting rod’s stress and deformation using Ansys. For this case, a fatigue and structural analysis will be performed. The axial compressive load is greater than the axial tensile load. Therefore, the design is only analyzed for the axial compressive loads. This analysis shows the importance of the solution of the connecting rod big end distortions in view of the changes in the bearing clearance at the most important variants of the stress[9, 11]. This variant is frequently overlooked and primary importance is attached to the strength stress which however does not have to be limiting one and Fatigue analysis and determining if design of connecting rod is safe or not.
