The connecting rod is the intermediate member between the piston and the Crankshaft. Its primary function is to transmit the push and pull from the piston pin to the crank pin, thus converting the reciprocating motion of the piston into rotary motion of the crank. Existing connecting rod is manufactured by using Carbon steel. Composite materials are now a day widely used in the engineering field. The general characteristics possessed by the composite materials are found to be the reason for using it in the automotive applications. The objective of the project is to design and Static Thermal analysis of connecting rod using metal matrix composite (MMC) with different materials ( Al 6061-1.5%B4c-1.5%Sic MMC Material, Al 360 Material, 6092 Sic/25 P-T6 Al MMC Material, Steel C45) The connecting rods are commonly used in the internal combustion engines and are subjected to millions of varying stress impacted. While the Composite connecting rods are lighter and may offer better compressive strength, stiffness and fatigue resistance than conventional connecting rod their design still represents a major technical challenge. In this project both the standard material and composite connecting rods are modeled and analyzed using catia v5 and ANSYS WORKBENCH 16.2. software respectively. A comparative study was undertaken to predict the structural and thermal behavior of connecting rods using three dimensional finite element analysis model, and to determine the most cost effective modeling and analysis approach. The finite element results verify that the performance is same as that of standard steel connecting rod. The stress and static Thermal analysis of the composite connecting rods is found to be better than that of the standard connecting rod. Finally concluded the suitable material of connecting rod based on the stresses, strains, deformations, shear stress, temperature distribution, heat flux values.
