Abstract
Piston is one of the critical components of an engine as combustion flame directly hits the piston surface. The aim of this research is to develop a methodology to select the material of piston for a new design of engine by using multi-criteria decision making (MCDM) method to solve the piston material selection problem. The Analytical Hierarchy Process (AHP) is designed to select material of the piston for a particular application. Open source data related to critical parameters of Caterpillar engine (viz. temperature and peak cylinder pressure) are considered, which directly affect the strength of piston material. To accurately predict the values of these parameters Ansys forte FEA simulation tool is used for combustion analysis. Simulation results are used as input to design material selection benchmark using AHP methodology. From the results obtained from Ansys forte simulation used as input to AHP based MCDM design methodology turned out to be fruitful for selecting Piston material for rapid decision making at the designer level.
