Optimization of Flywheel Design for the Engine CT-195 to Reduce Weight & Minimized Cost

Abstract

A flywheel stores energy in the form of kinetic (rotational) energy. Whereas each energy storage system has its inherent advantages and disadvantages compared to the others, it is the overall system performance and simplicity of flywheels that make them especially attractive for a variety of applications. Flywheel is mechanical device which is used to store the kinetic energy. There are many causes of flywheel failure. But maximum tensile and bending stresses induced in the web and rim under the action of centrifugal forces are the main causes of flywheel Failure. By changing the dimensions and shape and the materials and use such materials which increases stored energy and maintain minimum stresses with reduce mass of flywheel. It shows that smart design of flywheel geometry could both have a significant effect on the Specific Energy performance and reduce the operational loads exerted on the shaft/bearings due to reduced mass at high rotational speeds. we will compare the theoretical values of moment of Inertia with the Creo-Mechanic values so that the clear objective of the project can be seen. Our Main object is to optimise the flywheel weight without changing other important parameter like moment of inertia and its kinetic energy storage capacity.

Introduction

I. INTRODUCTION

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 (reciprocating) engine, or when an intermittent load, such as a piston pump, is placed on it. Flywheels are typically made of steel and rotate on conventional bearings; these are generally limited to a revolution rate of a few thousand RPM. Some modern flywheels are made of carbon fiber materials and employ magnetic bearings, enabling them to revolve at speeds up to 60,000 RPM. Carbon- composite flywheel batteries have recently been manufactured and are proving to be viable in real-world tests on mainstream cars. Our aim is to increase the amount of rotational energy stored in the flywheel during the working cycle by using different materials. This will help in the improvement of efficiency of the engine and makes the vehicle movement faster.

Design and Analysis of Flywheel for Small Scale Energy Storage System using Different Structures and their Comparison -Energy can't be created nor be destroyed but it can also be stored for later use. Flywheels made of steel are already used in many applications which run at comparatively medium speeds and are quite heavy like UPS Flywheels but the objective of this research is designing a flywheel that should be lightweight and can rotate at high speeds which can store energy for long time. Design and analysis of flywheel in petrol engine -A flywheel is an energy storage device. It is used in machines serves as a reservoir which stores energy during the period when the supply of energy is more than the requirement and releases it during the period when the requirement of energy is more than supply. The modelling of flywheel is created in CATIA tool and is imported to ANSYS for analysis. Finite Element Analysis is used to calculate the stresses inside the flywheel. Design and Analysis of Various Shapes of Flywheel In present investigation, to counter the requirement of smoothing out the large oscillations in velocity during a cycle of a mechanism, a flywheel is designed, optimized and analysed. By using optimization approach to optimize various parameters like cost, stresses, energy etc. for flywheel and to apply an approach for modification of various working parameter like efficiency, output, energy storing capacity, the results compared with existing flywheel result. Based on the dynamic functions and specifications, of the system the main features of the flywheel is initially determined, the detail design study of flywheel is done and by using any one of the optimization techniques and approach for modification, structural analysis is done.

We got Approx.1.41 Kg weight reduction and It will not change its strength regards storage of energy and also All stresses and failure parameter found under permissible allowances.
