Buckling Analysis and Shape Optimization of Connecting Rod using FEA
Journal Title: REST Journal on Emerging trends in Modelling and Manufacturing - Year 2016, Vol 2, Issue 2
Abstract
In a reciprocating engine, the connecting rod is a one of the most dynamic component of a vehicle that are bear static and dynamic fluctuation of various loads. In operation, the connecting rod is subjected to various complex loads of periodic changes: power thrust from piston pin, high tensile load due to inertia and high compression load due to compression of fuel, whereas bending stress caused by the thrust and by centrifugal effects. In the present investigation, a buckling analysis of connecting rod made up of forged steel used in SUZUKI SPRINT1.0L engine is conducted. This connecting rod is available for import, domestic and vintage. After measuring all dimension of connecting rod, the geometric models were developed using CATIA V5 for buckling analysis and it was analyzed in ANSYS 15 workbench that provides a highly interactive and visual environment to analyze product design performance. Therefore, this study has dealt with gradually changing the cross-sectional area of the connecting rod to perform buckling analysis at varying load and stress conditions. For this analysis, drawing the conclusion that the stress induced at the bigger end of the connecting rod is greater than the smaller end. Therefore, the shifting the stress from the smaller cross sectional area to the middle of the connecting rod by gradually reducing the cross-sectional area of the shank. The topology is used to achieve the objective of optimization in order to improve the shape of the connecting rod.
