摘要

The objective of study is performed on a cast iron connecting rod of a compressor for the static and dynamic analysis. Literature survey suggests cyclic loads comprised of static tensile and compressive loads are often used for design and analysis of connecting rods. The S-N approach by Modified Goodman criterion to fatigue life prediction of the connecting rods is presented. The possibility failure of the connecting rod approach by Failure Index is the ratio of Maximum Principal Stress to yield strength of material. The three-dimensional finite element model is constructed in PRO-E and used for Analysis. The model is meshed in ANSYS workbench and used for Analysis.
