MOORA recommends Structural steel as the best material and Ti6242S as the worst option. The recommendations of MOORA are in confliction with COPRAS.
COPRAS recommend Ti6242S as the best material and Structural steel as the worst preference. The weights of the individual output responses are evaluated through CRITIC method and utilized for calculating the weighted normalized matrix. The analysis results are further taken as input for multi criteria decision making to identify the best and worst material options through COPRAS and MOORA. Structural steel, Aluminium Silicon composite, AISI 4140 alloy steel and Ti6242S are the materials considered for static structural analysis to evaluate total deformation, strain energy, equivalent von mises stress and equivalent elastic strain by varying the torque for a spur gear pair. The present work aims to conduct structural analysis of spur gear pair subjected to different torque values such as 132, 190 and 225 Nm.
The material selected for a product to serve a particular function need validation through certain analysis for the application desired. Structural analysis of components is an important task in design phase which ensures the success of the design before stepping for product manufacturing.
