| Abstract | ||
| This paper is concerned with a stress analysis in a bearing under unbalanced forces of the journal Some aspects of mathematical modeling of rotating structures were considered. “Finite Element Method” is formulated for modeling rotating structures. As an application, a test rotor mounted on two-lobe hydrodynamic hearings is presented. Unbalance response calculations for various unbalance magnitudes are carried out in the bearing location. The bearing coefficients were found at rotational speed of 4OOO rpm. An accurate identification of bearing force parameters, i.e. stiffness and damping coefficients is presented by a classical linearized model. The bearing support forces in flexible rotor-bearing systems are presented as a function of unbalance response of the journal. The calculation of the bearing stress due to rotor unbalance are carried out using ANSYS. The ANSYS program gives a good aids in understanding the stress analysis in the bearing under the action of journal rotation. | ||
