摘要
转子系统的许多非线性因素由于转子偏心的存在而得到放大 ,至使转子与静件容易出现碰磨现象。本文针对转子系统偏心所引起的离心力提出一种主动控制方法 ,使系统避免出现碰磨 ,同时使挤压油膜阻尼器所产生的非线性不稳定影响最小。本文引入磁轴承理论对转动圆盘进行主动控制 ,并进行了仿真计算。
Nonlinear element of a rotor system is amplified because of the rotor system's eccentricity. It easily causes rub impact between the rotors and the stator. This paper study the influence of the eccentricity of a rotor system on its rub impact characteristics and present an active control method to prevent rub impact of rotors and stator, and at the same time, the influence of SFD is reduced. The paper use the theory of magnetic bearing in active control for rotational pan. Simulation results show that our method is feasible and effective.
