FEA Analysis of Weight Reduction of Flywheel

Flywheel is a device to smoothen the cyclic fluctuation of speed change when delivering constant output power from the engine. The main objective of the project is to reduce weight of automobile. If Engine flywheel has more weight than its need, then it will decrease fuel efficiency. If engine flywheel has less weight than its need, it will consequently enhance speed fluctuation, vibration and noise. Researcher has taken up one case study of Tata truck (LPT2521BS IV) for weight reduction without changing energy storage capacity. The author has reduced the weight by changing the geometry. The geometry has been changed in such a way that radius of gyration is changed, weight is reduced but mass moment of inertia remains unchanged. Different Researcher also used different hole pattern at different radius to take advantage of reducing weight. Modified flywheel has been manufactured by machining process on actual flywheel. It will be help in Verified “ANSYS� analysis result. So, the paper focuses on 1. Different Geometrical modeling with actual and modified flywheel 2. “ANSYS� analysis.
