Static, Fatigue and Modal Analysis of Connecting Rod under Different Loading Conditions

Connecting rod is a major link between piston and crankshaft. Its primary function is to convert reciprocating motion into rotary motion of crankshaft. Connecting rod is subjected to more stress than any other engine components. In this study static and modal analysis is performed .The S-N approach by modified Goodman criterion to the fatigue life prediction of the connecting rods is also presented. The model is developed using Solid Modelling software-Solidworks2013 .Further finite element analysis is done using Ansys14 Workbench to determine the von-mises stresses and strains, fatigue life and modal frequencies under different loading conditions.
