This document provides details about optimizing and analyzing a flywheel for a major project. It includes an abstract, introduction, literature review, research methodology, advantages and disadvantages of flywheels, and applications. The introduction explains that a flywheel stores mechanical energy to smooth out torque and speed fluctuations. The research methodology section outlines modeling the flywheel in CATIA and analyzing it in ANSYS to determine stresses and deformation. The advantages include high energy storage and power output while being safe, reliable, and low maintenance. Applications include use in wind turbines, electric vehicles, locomotives, and electricity grids.
