含双时滞紊流滑动轴承转子系统的动力学行为分析
Dynamic Behavior of Rotor System with Double Time Delays Supported on Turbulent Flow Sliding Bearing
摘要
Abstract
Based on the inevitable phenomenon of time delay in the active control,the dynamical model of turbulent flow sliding rotor system which has double time delays was established by using the model of infinitely short journal bearing.The dynamical equation was solved based on the precise integration method,and the model of infinitely short journal bearing was used to solve the oil film pressure,and the response of the bearing-rotor system was analyzed by using the orbit diagram and the time series.The results show that the small delay does not guarantee the stability of the system,and the stability of the bearing-rotor system can be obtained when the control gains match the time delays.关键词
