Design and Analysis of Connecting Rod with Used Various Aluminium Alloy Materials

Abstract

The aim of this work is to static analysis of connecting rod with used various type of aluminium alloy materials. The connecting rod is the transitional part between the piston and the crankshaft. Its essential capacity is to transmit the push and pull from the piston pin to the crank pin, in this way changing over the reciprocating motion of the cylinder into turning movement of the crank. The capacity of connecting rod is to transmit the push of the piston to the crank shaft, and as the outcome the reciprocating motion of the piston is interpreted into rotational movement of the wrench shaft. It comprises of a pin end, a shank section and a crank end. Pin end and crank end pin holes are machined to allow exact fitting of bearings. Consider SI engine (two-wheeler bike engine) connecting rod. As per calculation combustion pressure 8 MPa and other end fixed. Its length 124 mm and thickness 14 mm. Generally used connecting rod material is SEA8620. Its yield stress value 833 MPa and generated von mises stress 70 MPa as per ANSYS simulation. So, its safe criteria and factor of safety 16. When we are using connecting materials aluminium alloy like AL360, AL356, AL383, AL390 and AL413. Its respected yield stress value 170 MPa, 180 MPa, 172 MPa, 248 MPa and 180 MPa. Its ANSYS simulation von mises stress and deformation respected 70.418 MPa, 70.91 MPa, 70.91 MPa, 79.773 MPa and 79.77 MPa. Deformation value 0.052165 mm, 0.051518 mm, 0.052244 mm, 0.04742 mm and 0.058774 mm. as per simulation and calculation work AL390 is best materials assign for connection rod.
