1. 1. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Simon Pääjärvi; [2022]
   Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

   Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE
