THERMAL ANALYSIS OF THE PISTON USING COMPOSITE MATERIALS

Abstract

A piston is a component of reciprocating engines, reciprocating pumps, gas compressors and pneumatic cylinders, among other similar mechanisms. It is the moving component that is contained by a cylinder and is made gas-tight by piston rings. The piston transforms the energy of the expanding gasses into mechanical energy. The piston rides in the cylinder liner or sleeve. Pistons are commonly made of aluminum or cast iron alloys.  The main aim of the project is to design a piston for 1300cc diesel engine for two materials Cast Iron, Aluminum Alloy and composite materials and steel. The designs of the piston are modeled using CREO software. The designs are evaluated by structural and thermal analysis by applying pressures and temperatures respectively. The result is evaluated by checking the stress, displacement, thermal gradient and thermal flux to decide the best design of the piston. Structural and Thermal analysis are done in ANSYS software.
