Simulación numérica de contacto entre superficies con movimiento relativo para predicción de desgaste en cojinetes de fricción de aleación de aluminio

Abstract

In the present technical study, a numerical simulation of contact of surfaces with relative motion for the prediction of wear in journal bearings was carried out. Firstly, a literature review of the wear of this type of bearings and a study of the finite element method in ANSYS Workbench was carried out. In order to reduce the computational cost, 2D Pin on disc and Pin on block configurations were considered. The numerical simulation of contact was made in the Transient Structural module where a coupled thermo-mechanical analysis can be carried out. For the determination of the wear in the aluminum, pressure and temperatures distributions were obtained in stable state and transient state at different loads. The results were compared with the results found in specialized documentation and through a comparison the error corresponding to each type of analysis was determined. Finally, with the temperatures and pressures, the linear wear of the Al-6061 journal bearings was established. In the end, it is stated that this document presents practicality both in the industry and in the field of research.
