Research on nonlinear behavior of rotation vibration system

The rotation mechanical vibration system is a certainty complex nonlinear system, in this paper, we research this system based on chaotic theory, the nonlinear rotation system will be in chaotic state when the rotation speed changed, the dynamic behavior of the system at stable oscillation, according to the values of frequency and amplitude of the steer signal, we can get the basic character s of fault information, the numeric simulation results of chaotic behavior of mechanical vibration system and data analysis of the real mechanical vibration system show that the mechanical vibration systems chaotic character.
