Selection of Flywheel Material using Multicriteria Decision Making Fuzzy Topsis


Flywheel is used to store rotational energy and subjected to more stress and strain. The selection of material have a vital role in the fabrication of flywheel. In this paper we are using Multi Criteria Decision-Making Fuzzy Topsis tool for selecting the material for flywheel. As per the literature review best suitable 5 materials (Carbon steel 1065, Alloy steel AISI 4340, Maraging steel 18ni, Alloy steel AISI E9310 and Stainless steel) are taken into consideration for selection and with the help of decision makers 5 material properties (Density, hardness, young’s modulus, bulk modulus and poison’s ratio) are chosen for analysis. Weightages are provided by 3 decision makers and averaged for analysis. As per the analysis maraging steel 18ni chosen for the fabrication of flywheel and the least material will be carbon steel 1065. In future more suitable materials and properties will be chosen for analysis which will provide more accurate results and the same method can be applied for selection of materials for other applications.
