Thermal Analysis of Piston Using Convex and Concave Profile of Piston head

Abstract

The purpose of this investigation work is to optimize the stress variations on the upper face of the piston at actual engine condition. In this analysis pressure on the piston surface examined, thermal behavior investigation is performed. The functions used for the investigation is operating gas pressure, temperature and material functions of piston. The analysis performed that because of temperature whether the upper face of the piston may be damaged or broken through the working conditions, as damaged or not working parts are so costly to change and usually are not simply available. Concave and convex Profile of piston designed in Solid work 2016 used to design piston geometry and for FEM analysis on optimize thermal behavior of piston ANSYS 14.0 used. Aluminum alloy and grey cast iron material used for designing of piston. The stress and displacement are analyzed for the piston by applying pressure on it in Structural analysis. By observing the analysis results, we can decide whether our designed piston is safe or not under applied load conditions. The thermal flux, thermal temperature distribution is analyzed by applying temperatures on the piston surface in Thermal analysis.
