Abstract: This paper presents static structural analysis of engine camshaft by FEA. The Camshaft is important parts in the IC engines. This camshaft rotates at high speeds causing stress and vibrations in the system. Camshafts are also subjected to varying contact fatigue loads due to the contact of the plunger on the cam. These exact values are needed to be determined to avoid failure in camshaft. The objective of the project is to perform stress analysis of camshaft. In this project the standard camshafts is modeled and analyzed using Pro-E Wildfire 4.0 and ANSYS WORKBENCH 11.0 software respectively. The model is created by the basic needs of an engine with the available background, such as forces acting over the cam by means of a valve while running at maximum speed. Here the approach becomes fully CAE based. CAE based approach enriches the Research and limits the time duration. A study has been undertaken to predict the structural behavior of camshafts of different materials using three dimensional finite element stresses. Four Materials namely aluminum, steel are taken into the consideration. The results of Stress and maximum displacement are calculated and compared for all the above materials. ANSYS values are compared with the theoretical values. The conclusion is to focus towards proper material for the camshaft to reduce maximum displacement and stress. The material steel comes out to be the best material for the manufacture of camshaft based on the analysis.
