Once the CAD model is obtained, modal analysis is performed on CAM SHAFT by applying Cast Iron material, Aluminium Alloy and Billet steel material.In this work, a camshaft is designed for multi cylinder engine and 3D-model of the camshaft is demonstrating using modeling software CATIA V5 R18. The model created in CATIA V5 R18 is transported in to ANSYS 14.5.
