Abstract

Rotor vibrations and its control is an important subject in many industries such as power plants and gas stations. When lateral vibrations of rotors during operation exceeds allowable level, a huge damage will be occurred. SURGE and STALL may be some common reasons of these vibrations. This paper aims to present a simple model for SURGE and STALL and assumes that its effect as a concentrated force acting on a rotor- disk system. This is a basic and conceptual model for future investigations in this area. Therefore, the effect of a concentrated axial force exerted on an assembled disk on a rotating shaft is investigated theoretically. Equations of motion are derived using Timoshenko beam theory. This governing equations consist of four coupled partial differential equations. Since these equations are complex, coupled and have time- varying coefficients, they are solved using a combination of Galerkin and Newmark methods. Numerical examples are analyzed as well. The accuracy of these equations is verified for a simple beam. Results indicate that the AXIAL LOAD has a considerable effect on the lateral vibration amplitude of the rotor and this simple proposed model can be improved for next studies in this area.
