Finite Element Analysis of a Rotor Supported with Hydrodynamic Journal Bearings

Ranjit Kumar, A (2015) Finite Element Analysis of a Rotor Supported with Hydrodynamic Journal Bearings. BTech thesis.



This work was aimed at studying and performing an analysis of a Rotor Bearing System with Journal Bearings by finite element analysis techniques. The Eigenvalue problems for equation of motions of Finite elements applied to rotors and bearings are stated. Design of a rotor bearing system is based upon calculation of various natural frequencies, critical speeds and stability analysis. The results for up to 80 element mesh were plotted. A computational procedure for finding natural frequencies of vibrating rotors with damping, gyroscopic and inertial effects is presented. The dynamic coefficients associated were computed by adopting perturbation scheme on governing equation for fluid film bearings. Rotating systems are widely studied under rotordynamics in industries for designing the systems below critical speeds and stability.
