Mode shape analysis of a diesel engine CAM shaft
A CAM shaft is a shaft to which CAMs are fitted or an integral form parts. Eigen frequency analysis has performed on a CAM Shaft design to predict various mode shapes. In internal combustion engines with pistons, the camshaft is used to operate poppet valves. It then consists of a cylindrical rod running the length of the cylinder bank with a number of oblong lobes protruding from it, one for each valve. The cam lobes force the valves open by pressing on the valve, or on some intermediate mechanism as they rotate. A three-dimensional model of CAM shaft is designed and numerically simulated for various mode shapes while in rotation.
