Structural and Thermal Analysis of Diesel Engine Piston by Changing the Number of Ribs and Materials

Abstract

A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders 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. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod. The power produced by the engine & its efficiency depends on piston. In this paper both Structural & Thermal Analysis is carried out on Diesel engine piston considering three materials such as Aluminum Alloy (Al6061) & Forged Steel also by varying number of ribs. For this Analysis, Modeling of a piston is done using Catia V5 Software & then it is imported into Ansys Workbench. Stress, Strain & Deformation Values are decreased with the increase of Ribs in the Piston Design. The amount of heat flux is more for a piston provided with six ribs. Considering both Structural & Thermal Analysis it is observed that Aluminum Alloy with EIGHT Ribs has shown good results
