Design Modification and Analysis of Flywheel Using in Thresher Machine

A flywheel is a mechanical device with a significant moment of inertia used as a storage device for rotational energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a piston-based engine, such as a piston pump, is placed on it. The flywheel are different types such as solid disk, Spoke type, rim type, tapered type. In solid disk flywheel type it is provided with hub and disk. Solid disk flywheels are less capable of storing energy. Then spoke type flywheel are capable of storing more energy with greater moment of inertia than any other type of flywheel. In this work solid disk, spoke type flywheel are designed by using CATIA software. The spoke type flywheel is modeled with 6 spokes and 5 spokes with and without taper. Structural analysis and Modal analysis by using ANSYS software is done to determine the stresses and frequencies respectively by considering the different materials Cast iron, Aluminum Alloy 6061 & S-glass materials. From the above analysis, the better material for the flywheel is determined.
