This work presents a review of rotordynamics and bearings (focusing in aerostatic bearings) based on Chiarelli (2014). During the chapters the analytical and numerical models are presented in order to teach to the reader how to approach problems involving static and dynamic characterization and prediction of rotor assemblies. The numerical models are implemented in common use software such as ANSYS(R) and MATLAB(R) and the programs are shown at the end of the work.
