Natural frequency analysis of Automotive flywheel

A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have an inertia called the moment of inertia and thus resist changes in rotational speed. The amount of energy stored in a flywheel is proportional to the square of its rotational speed. Energy is transferred to a flywheel by the application of a torque to it, thereby increasing its rotational speed, and hence its stored energy. Conversely, a flywheel releases stored energy by applying torque to a mechanical load, thereby decreasing the flywheel's rotational speed. This experiment deals with finding the natural frequency and mode shapes of a automotive crankshaft flywheel. A cad model of flywheel is developed and eigen frequency has performed using finite element analysis. The above CAE image shows displacement contour plots under certain frequency level.
