Abstract
Assessments of verification, validation and quantification of uncertainties are being increasingly used to certify that softwares are free of errors. The benefits imply greater relevance of the assessed softwares in the market and experimental tests can be dispensed from future projects, decreasing lead time for launching a product while keeping its reliability. This work focuses on a Rotor Dynamics software verification, validation, and uncertainty quantification, regarding the ASME V&V 10, 10.1, and 20. Since the ASME V&V 10 and 10.1 standards deal with the verification, validation and quantification of uncertainties in the field of solid mechanics, they will be used to evaluate the rotor shaft discretization. On the other hand, the ASME V&V 20 standard is related to fluid mechanics; therefore, it will be used to assess the discretization of the oil film mesh, present in the fluid film bearings. Firstly, the analytical and numerical models are briefly presented. Both are respectively used in the verification and validation assessments. The verification assessment is divided in three parts: the rotor static and dynamic behavior (without hydrodynamic bearings); the hydrodynamic bearings themselves; and the static and dynamic behavior of the rotor supported by hydrodynamic bearings. Then, the validation assessment is achieved using a set of experimental data, which contains unbalance response functions (URF) at bearings and disc positions. Finally, the conclusions and remarks are presented.
