Abstract

For centuries, the motion needs of vehicles have mostly been met by using reciprocating engines. The connecting rod also mediates to convert the movement of the piston in these engines into the rotational movement of the crankshaft. In this study, it was aimed to compare the connecting rod designs using titanium and aluminum materials and the designs using ultra high strength steel (UHSS) in the examination of vibration data in connecting rod design. Since connecting rods are exposed to a wide variety of loads during their operation, the durability, life, and cost of the material from which they are produced come to the fore as important factors. In this study, at first connecting rod design was made with the help of CAD (Computer Aided Design) program, then different material applications were analyzed with the finite element method (FEM). The ultra-high strength steel connecting rod design will also be analyzed under specified conditions through the modal analysis module. The obtained results will be compared with aluminum and titanium designs and presented as natural frequency, von Mises stress, and deformation distribution figures. The titanium connecting rod design has a lower natural frequency mode than other models, while the UHSS design follows immediately. The total deformation values of the UHSS connecting rod design are lower than the other two design values
