电磁轴承-转子系统的非线性动力学行为分析
Research on the Nonlinear Dynamic Behavior of Electromagnetic Bearing-Rotor System
摘要
Abstract
On the basis of considering the nonlinear rubbing force,and based on the dynamics model of electromagnetic bearing-rotor system,the model has been made dimensionless.For nonlinear dynamic behavior of the system,which is caused by unsteady oil film force and nonlinear rubbing force coupling,numerical simulation with Runge-kutta method has been adopted.The chaotic characteristics such as the friction factor,system stiffness ratio,quality of eccentricity ratio and so on,caused by parameter changes,are obtained.In the system running,we find that rich nonlinear phenomena like periodic motion,periodic and chaotic exist in the system.关键词
