This research project has as main objectives the analysis of fatigue in lightweight crankshafts subjected to bending and torsion loading. This analysis will first be carried out numerically, through the development of a methodology for implementation of the finite element method. To perform the simulations, it will be used a commercial tool, Ansys Workbench. Subsequently, experimental fatigue tests will be performed. At this stage, an experimental test rig for dynamic tests of the crankshafts will be developed. Then, lightweight crankshafts prototypes will be manufactured by rapid prototyping and then assembled and properly instrumented. The experimental fatigue tests will then be carried out using the designed test rig and the results will be correlated with the results obtained numerically. This project is part of FAPESP "Centro de Pesquisas em Engenharia "Prof. Urbano Ernesto Stumpf" " process 13/50238-3. (AU)
