Abstract

In this paper the dynamic behavior of a rotating system which includes rotor (shaft), ball bearing anddisk in stationary condition and different speeds is investigated. There are nonlinear characteristics inthese systems which make the linear modeling inaccurate. So, in this paper the nonlinear dynamicequations of the system are derived and solved. To derive the equations of the system, Hamiltonianmethod is used, and complex coordinate transform is employed to reduce the number of equations.After solving the equations, to investigate the vibrational properties of the system, time responsediagram, dynamic orbit, frequency response, and mode shape of the rotor is plotted. To validate theanalytical results, FINITE ELEMENT method by ANSYS (workbench) software is used. There is goodconformity between the analytical results and FINITE ELEMENT results in resonance frequencies of thesystem in the first three modes which indicates the sufficient accuracy in NONLINEAR MODELING. It can beconcluded from NONLINEAR MODELING that the decay rate is negative for the all modes, which indicates thestability of them. Also, the maximum vibration amplitude in the bearing and rotor occurs in third andsecond modes respectively. UNBALANCE PHASE DIFFERENCE of 90 degrees in two discs causes the excitationof all three frequency modes, whereas by UNBALANCE PHASE DIFFERENCE of 0 or 180 degrees in two discs, only the odd modes (first and third) and the even modes (second) are excited respectively
