Fracture, Fatigue Growth Rate And Vibration Analysis Of Camshaft In Railways

  Praveen Kavuri,  Dara Ashok

The cam shaft is the device regulates the opening and closing of the two valves. The connected parts are push rods, rocker arms, valve springs and tappets. It had number of lobes protruding over a cylindrical shaft, one for each valve. The cam lobes force the valves to open by or on some intermediate mechanism as they rotate. Also, this same rotation of the shaft offers the drive to the ignition system. Camshafts are made from steel and sit below the cylinders and pistons in the engine block. At present, camshafts are being manufactured in railways by rolled steel bars and machined by turning and excessive removal of material. We are replaced with aluminum alloy 6061, forged steel & cast iron. For checking, 3D-model of the camshaft is created using modeling software CREO parametric software and analysis done in ANSYS with different materials aluminum alloy, forged steel & cast iron. In this paper, the static analysis and Modal analysis done to conclude the deformation, stresses, strains and the deformation with respect to frequencies at different mode shapes and fatigue analysis is to estimate the life of the component.
