Abstract

Background/Objectives: The present investigation guides through the design, analysis and material selection process of Subaru EJ25D gasoline engine flywheel to reduce the weight of the flywheel without compromising its performance. Methods/Statistical Analysis: The flywheel was modeled using 3D modeling software Solid works. The validation of the strength of the flywheel was done by calculating and applying the forces on the flywheel using ANSYS software. The Finite Element Analysis (FEA) was conducted by considering the centrifugal forces acting on the flywheel. Structural analysis of the flywheel was done to validate the use of the alternate materials for constructing the flywheel. A comparative analysis of the stresses, total deformation and safety factor of the flywheel made of cast iron, titanium alloy, E-glass and aluminium alloy was reported. Findings: Based on the analysis, Aluminium alloy was found to be the most suitable material for constructing the flywheel. Specific tensile strength was considered for selection of the alternate materials of the flywheel. This paper also demonstrated the feasibility of using non-conventional materials like composite for manufacturing flywheels. Applications/Improvements: Flywheels which are a commonly used part in automobiles are subjected to multiple varying stress cycles which ultimately can lead to its failure.

Abstract

The current situation of demonetization is a subject of discussion. The major area which is affected with this step of regime is consummately the sector which was working on the substratum of daily cash flow. The middle level and the higher income individual are not much affected with this situation because they have their own ways to tackle the issue but the major quandary and confusion aroused with the lower income group people.
In this study a comparison has been made between the current scenario, the current policy for demonetization and the one that happened in year 1978, with regard to both the advantages as well as the disadvantages of this to the national economic policy and the public at large. This study is focused on the areas which were unrevealed and left out where demonetization of higher bank notes leaves its print in illegal ink. It was understood that the biggest beneficiaries of demonetization move was the E-wallet companies, the startups like paytm, freecharge etc.
