Abstract:- The net torque imparted to the crankshaft during one complete cycle of operation of engine fluctuates causing a change in the angular velocity of shaft. In order to achieve a uniform torque, an inertia mass in the form of a wheel is attached to the out shaft and the wheel is called the flywheel. The finite element model of flywheel is considered and the analysis is done with the help of ANSYS package. ANSYS is general purpose software, which can be used for almost any type of finite elements analysis virtually in any industry – automobiles, aerospace, railways machinery, electronics, sporting goods, power generation, power transmission and bio-mechanics. General purpose also refers to the fact that software can be used in all disciplines of engineering-structural, mechanical, electrical, electromagnetic, thermal, fluid and bio- medical. The project involves the design and analysis of flywheel to minimize the fluctuation in torque, the flywheel is subjected to a constant rpm. The objective of present work is to design and optimize the flywheel for the best material. The flywheel is modeled with solid 95 (3-D element), the modeled analyses using free mesh.The FEM mesh is refined subject to convergence criteria. Preconditioned conjugate gradient method is adopted during the solution and for deflections. Von-misses stress for both materials (mild steel and mild steel alloy) are compared, the best material is suggested for manufacture of flywheel
