Abstract:

The application of load acting on a connecting rod during the combustion of fuel, often leads to the failure of the connecting rod and engine case. In this study, a connecting rod was designed based on selected dimensions and material in SOLIDWORKS tool. The connecting rod structural failure analysis under tension load has been carried out using SOLIDWORKS Finite Element Analysis (FEA) tool with aluminum alloy (AL2024) and grey cast iron material. The results show that with the selected design parameters and material, higher stresses are induced in the middle region (I-section) of the connecting rod if it is made of grey cast iron. The deformation of the model made of grey cast iron is also worse than the AL2024. The elongation of grey cast iron material is higher than the Al2024 by 0.1634 mm, and 0.14947 mm in Al2024 material. This study concluded that for better connecting rod design, the aluminum alloy Al2024 is a suitable material with very light weight and high tensile strength under 20kN load.
