Özet

Connecting rods are one of the most used parts in internal combustion engines today, and they have the ability to convert linear motion to rotational motion and vice versa. Different forces acting on the connecting rod cause serious deformation, fatigue, and damage on the connecting rod. The automotive industry is also working on connecting rods with good durability, longer service life, and lighter weight. In this study, static and fatigue analyzes were carried out using the finite element method by applying C45 steel, AISI 4340 steel, and Titanium material to the connecting rod design. Connecting rod designs were designed with the CATIA program and analyzed by the Ansys program. The total deformation, equivalent elastic strain, equivalent stress, factor of safety, life, damage, and fatigue sensitivity parameters of the materials were inquired by analysis. When C45 steel is used instead of the titanium material used in the existing connecting rods, it has been observed that the deformation, stress, and life values close to the titanium material are obtained. With the results of the analysis, 2.07 times less deformation, 0.3% higher stress, and 10 times more cycle number are obtained with C45 steel material in comparison to titanium.
