初轧机主传动系统扭转自激振动的稳定性

The Stability of Self-excitation Vibration in the Main Gearing train of the First Rolling Mill

用变量摄动法对初轧机主传动系统扭转自激振动的稳定性进行了初步研究 ,讨论了稳定性条件 ,为初轧机打滑状态的诊断。

In this paper,an initial research on the stability of self excitation vibration which occur in the main gearing train of the first rolling mill is made by the method of variation and perturbation.The paper also discusses the condition of stability and provides a consult basis for the diagnosis and monitor of the state of the first rolling mill.
