Static structural and linear buckling analysis of diesel generator connecting rod

Abstract

Connecting rod is one of the major components in an internal combustion (IC) engine which provides reciprocating motion from the rotary motion to the piston. In an IC engine the high combustion gas will produce, due to which high loads will developed in the connecting rod. It is very important to study the behaviour of connecting rod in an IC engine for diesel generator due to high pressures on connecting rod. It is also important to study the buckling load of the connecting rod which may reduce the failure of connecting rod. Hence in the project the static structural and linear buckling analyses have been conducted on a connecting rod for a diesel generator, resembling an exact diesel generator connecting rod. Estimation like the maximum stresses, maximum deformation, buckling load factor and critical buckling load are determined for different materials like aluminum alloy 6061, titanium alloy, magnesium alloy and aluminum boron carbide and new modified design. CAD model of connecting rod has been generated by using industrial CAD tool solid works and analysis has been done by using industrial CAE tool Ansys Workbench. In this project the results of static and buckling analysis has been compared and presented the suitable design of connecting rod for better performance. Finally, the results are justified by suggesting why Al alloy holds better replacement that other mentioned alloys
