The purpose of this paper is to study the dynamic behavior of a journal bearing sleeve center by using a transient approach. Unlike other papers presenting the motion of the shaft inside the bearing sleeve, in this paper the rotor is considered rigid having only a small unbalance and the motion of the sleeve center is analyzed. The sleeve is supported by elastic elements. In addition, the axial ends of the bearing are exposed at two different pressures. To the authors’ knowledge, this paper is the first study of such a bearing configuration. Moreover, the influence of the stiffness and damping properties of the elastic element on the sleeve dynamic behavior (trajectories, motion frequencies, etc.) is also analyzed. Relative and absolute trajectories of the sleeve center and FFT analysis of the motion are presented.
