| Abstract: | In allusion to the specific features of a nonlinear rolling element bearing-rotor system with bearing house's looseness at one support,the nonlinear vibration of the system is formulated based on rotor dynamics, Hertz theory and nonlinear dynamics.The complex motions including the period doubling and chaotic motions and the transformational laws are studied with the increase of the rotating speed and the augment of the clear- ance by means of numerical simulation.The analysis results in this paper provide some reference for diagnosing the fault of bearing house's looseness. |
