Abstract

he stability of bearing-rotor system is a very important problem for design, manufacturing, and operation of rotating machinery. The instability of rotor system will result in the strong vibration and even disastrous accident of machinery. The researches for decades indicate that the strong-nonlinear exciting sources such as oil-film forces, sealing forces and non uniform steam forces etc. all are main reasons which can make unstable accidents in rotating machineries. The oil-film forces are the leading nonlinear exciting source which makes the bearing rotor system to be a self-exciting vibration system and results in fatal accidents. So solution of nonlinear oil-film forces in sliding bearings is always very important for dynamic analysis of rotor-bearing system.
