ABSTRACT
A flywheel is an energy storage device. It is used in machines serves as a reservoir which stores energy during the period when the supply of energy is more than the requirement and releases it during the period when the requirement of energy is more than supply. The modelling of flywheel is created in CATIA tool and is imported to ANSYS for analysis. Finite Element Analysis is used to calculate the stresses inside the flywheel. The analysis on various geometric forms of Flywheel such as solid type, rim type, web type & spoke type of flywheel has been carried out and appropriate results have been extracted & moreover analysis has been carried out on the specific rotation of flywheel. For example, in I.C. engines, the energy is developed only in the power stroke which is much more than engine load, and no energy is being developed during the suction, compression and exhaust strokes in case of four stroke engines. The excess energy is developed during power stroke is absorbed by the flywheel and releases it’s to the crank shaft during the other strokes in which no energy is developed, thus rotating the crankshaft at a uniform speed.
