ANALYSIS OF PISTON AND CONNECTING ROD WITH DIFFERENT MATERIALS SUBJECTED TO STATIC AND DYNAMIC ANALYSIS

Abstract

piston is a disc which reciprocates within a cylinder. It is either moved by the fluid or it moves the fluid which enters the cylinder. The main function of the piston of an IC engine is to receive the impulse from the expanding gas and to transmit the energy to the crankshaft through the connecting rod. The piston must also disperse a large amount of heat from the combustion chamber to the cylinder walls. In this Project we describe the stress distribution of the piston by using FEA. The finite element analysis is performed by using computer aided design (CAD) software. The aim of our project is to design a piston for a two wheeler using Solid works software and analyses with Ansys, in this case we analyses our piston with existing material and different material and finally we conclude which material is more suitable for manufacturing of the piston. In this project we took steel as existing material and then analyzed model at high pressure values The piston investigate and analyzes with modified dimensions at the real engine condition during combustion process. The optimization is carried out to reduce the stress concentration on the upper end of the piston. With using computer aided design (CAD), Solid works software the structural model of a steel and Aluminum piston will be developed. Furthermore, the finite element analysis performed with using software ANSYS Connecting rod is replaced by aluminium based composite material reinforced with silicon carbide and fly ash. And it also describes the modelling and analysis of connecting rod. Fea analysis was carried out by considering two materials. The parameters like von misses stress, safety factor and displacement were obtained from ansys software. Compared to the former material the new material found to have less weight and better stiffness. It resulted in reduction of weight, reduction in displacement.
