DESIGN AND FATIGUE ANALYSIS ON METAL MATRIX COMPOSITE CONNECTING ROD USING FEA

COMPOSITE

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 fatigue analysis of metal matrix composite (MMC) connecting rod. The connecting rods are commonly used in the internal combustion engines and are subjected to millions of varying stress cycles leading to fatigue failure. While the Composite connecting rods are lighter and may offer better compressive strength, stiffness and fatigue resistance than conventional connecting rods and their design still represents a major technical challenge. In that project both the standard steel and composite connecting rods are modeled and analyzed using Pro-E Wildfire 2.0 and ANSYS 10.0 software respectively. A comparative study was undertaken to predict the structural behavior of connecting rods using three dimensional finite element stress and fatigue 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 fatigue analysis of the composite connecting rods is found to be better than that of the standard connecting rod. The connecting rod is modeled by using Pro-E and the part option is used to model this connecting rod. It is exported as IGES(.iges) file format to import into ANSYS software.
