   Sammanfattning : 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. LÄS MER

3. 2. Rotor Dynamic Analysis of RM12 Jet Engine Rotor using ANSYS

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Deepak Srikrishnanivas; [2012]
   Nyckelord :Rotordynamics; RM12; Jet engine; Gas turbines; Ansys; Dyrobes; Vibration; Rotor; Twin spool;

   Sammanfattning : Rotordynamics is a field under mechanics, mainly deals with the vibration of rotating structures. In recent days, the study about rotordynamics has gained more importance within Jet engine industries. The main reason is Jet engine consists of many rotating parts constitutes a complex dynamic system. LÄS MER

4. 3. Evaluation of COMSOL Multiphyscis for rotordynamical analysis

   Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

   Författare :Hessameddin Moradi Motlagh; [2012]
