Comparison between Two ANSYS Finite Element Modeling Methods of Multistage Centrifugal Pump Rotor

摘要：

In the last decades, many methods of ANSYS finite element modeling have been proposed. By comparing the two different methods of beam element modeling and entity unit modeling for multistage centrifugal pump rotor, we find that although both methods are insensitive to torsional vibration model, to some extent they affect other vibration models and result in certain deviation in calculation results. Using beam element modeling not only improves the calculation precision, but also saves computing resources. The Appropriate selection of the element type will reduce the amount of input data and computation time.
