The effect of unbalance on the cyclic stresses of a flexible rotor mounted on oil-film bearings using finite elements technique (ANSYS)‎

الملخص EN

Eccentricity problem is considered as one of the most important and common repeated problems in rotary shafts in all machines.

This will lead to generation of vibration and extra loads on bearings.

Also a non-uniformity can occur in distribution of applied load on all the surface of the bearing which being concentrated on one or two sides of the bearing surface.

The purpose of this research is to investigate the effect of the unbalance on the values of stresses and deflections for a flexible rotor supported by oil film bearings.

Various rotational speeds and unbalance effects has been taken in to consideration.

A dynamical model of the system has been built.

The parameters of journal bearing have been determined using MATLAB/ simulink software.

ANSYS program has been used for the analysis of the stresses produced during rotation.
