Camshafts used in the engines provide the required motion for the inlet and exhaust valves. These mechanical components convert the rotary motion into the linear motion and vice versa. In the present work, the main objective is to evaluate the dynamic response of the camshaft of an automobile made by different materials. To meet the higher target of power, cam shaft have to run at higher speeds. Because of this reason the cam shaft will be subjected to torsional vibrations due to gyroscopic effect and centrifugal force of the rotating elements mounted along with the shaft. Thus an analysis has been performed to find the deflections and stresses at the resonance frequencies of various materials like Aluminum-silicon carbide (Al-SiC), AISI 1065 Carbon steel, spheroid graphite cast iron, chilled cast iron and forged steel. An angular velocity of 785 rad/sec is given about the shaft axial direction. Both end of the camshaft is fixed in all Degrees of freedom except rotation. Finally, the results obtained for different materials are compared to find out the best material among them as the camshaft.
