Abstract

A flywheel is essentially a very heavy wheel that takes a lot of force to spin around .the shape of the flywheel plays an important role in storing capacity as well as to minimize the fluctuations of shaft .Flywheels are often used to provide continuous energy in system. And act as a reservoir by storing the energy. The parameters which affect the flywheel are material strength, geometry, and rotational speed .optimizing a flywheel means providing a framework for optimizing structures described by various possible physical or mechanical models .optimization helps to minimize the cost of the flywheel. Flywheel having efficient design maximizes the life and assures high reliability .This flywheel finds applications in punching press, sewing machine, I.C. engines ,pumps etc. the various shape for flywheel design are solid, rim, web and arm type flywheel in which stress variation is observed for various shape and size and optimizing the shape. Optimized design helps in reducing material failure occurrence due to high stresses, cost improvement. Geometry of the flywheel has a effect on specific energy.
