摘要
对简单转子支承系统的油膜稳定区进行了计算研究。通过建立包含支承阻尼和转子外阻尼在内的弹性支承滑动轴承系统模型,计算了该转子系统的油膜稳定界限,并对稳定界限进行分析,讨论了提高转子系统稳定性的措施。分析结果表明:减小转子系统的刚度,是提高系统油膜稳定性的有效办法。
This paper studies the film stability of a simple rotor support system.Through establishing the model of the system containing both support damping and rotor external damping,the stability boundary of this rotor system is computed and analyzed,and the measurment of improving stability of the rotor system is discussed.This indicates that reducing the stiffness of the rotor system is an effective method to enhance the film stability.
