Abstract

Connecting rod is one of the most important moving components in an internal combustion engine. It is the link between the piston and the crankshaft. Its primary function is to transmit power from the piston pin to the crankpin by so doing converting the reciprocating motion of the piston to rotary motion of the crankshaft. The connecting rod was modelled using Autodesk Inventor 2017 software. The modelled connecting rod was then imported into Ansys for further analysis. Static structural analysis was carried out on the connecting rod of the four different materials namely: structural steel, titanium alloy, grey cast iron and aluminium 7075 T6 alloy to determine the total deformation, equivalent elastic strain, equivalent Von Mises stress and the safety factor. When the deformations were compared it was found that Al 7075 T6 connecting rod yielded the highest deformation of 0.62979 mm representing 36% of the total deformation of all the four connecting rods. Structural steel connecting rod was found to have yielded the lowest deformation of 0.22733 mm representing 13%. When the stresses were compared it was found that, Titanium alloy and Al 7075 T6 connecting rods yielded the lowest Von Mise stresses of 372.51 MPa and 375.52 MPa respectively. This will boost the local automotive industry in Ghana since the Aluminium 7075 alloy can be obtained locally.
