DESIGN AND ANALYSIS OF FLYWHEEL IN PETROL ENGINE

Abstract

A flywheel used in machines which serves as a reservoir which stores energy all along the period when the supply of energy is more than the required energy and releases it during the period when the requirement of source is less than supply. For example, in Internal. Combustion (I.C). engines, the required energy is developed only in the power stroke which is lot more than engine load, and no energy is being produced during the suction process, compression and exhaust strokes in case of four stroke engines. The excess energy which is developed during power stroke is consumed by the flywheel and discharges it to the crank shaft at the time of other strokes in which no energy is produced, thus rotating the crank shaft at a constant speed.The flywheel is placed at one end of the crankshaft and delivers two objectives. First, through its inertia, it compensate vibration by smoothing out the power stroke as each cylinder fires. And the Second, one is the mounting surface used to nut the engine up to its load.The aim of the system is to model a flywheel for a multi cylinder petrol engine flywheel using the empirical formulas. A parametric model of the flywheel is designed using 3D modeling programable software called Creo. The forces assisting on the flywheel are also considered and calculated. The capacity of the flywheel is validated by applying forces on the flywheel in analysis software ANSYS. Structural study, model studys and fatigue study are done on the flywheel. Structural study is used to test whether flywheel withstands under working conditions are not. Fatigue study is done for knowing the life of the component.Model analysis is done to explain the number of mode shapes for flywheel.Analysis study is done for two materials Gray Cast Iron and S Glass Epoxy to compare the results.
