In this work, the mechanical behavior of a connecting rod of a two-stroke single-cylinder engine is studied by means of finite element analysis to reduce its weight. We investigated the static and dynamic stresses on the parts of the connecting rod, considering the boundary conditions of the Jovaj theory for the design of automotive conrods. Then, the maximum stresses of the models were compared to perform the optimization of the weight of the connecting rod, evaluating the sensitivity of the prototype, and geometry restrictions. For the study using finite element analysis, a connecting rod prototype designed at Universidad Industrial de Santander was used, within the project of reengineering the connecting rod of a two-stroke engine of small displacement for agricultural applications. The mechanical response of the designed conrod was evaluated, taking into account the mechanical stresses to which it is subjected during the operation of the engine. Finally, the design was revised to propose preliminary improvements in the geometry using topology optimization.
