摘要
本文把发电机轴系扭振的分析扩展到非线性领域,并对轴系扭振中的Hopf分歧现象进行了研究.利用时域仿真结果对从描述轴系扭振的近似非线性微分方程分析所得结果进行了验证.本文的研究表明,由于存在Hopf分歧现象,轴系扭振的不稳定范围明显小于应用特征根分析法所预测的范围.
This paper extends the analysis of torsional oscillations into the nonlineer range and in vestigates the Hopf bifurcation phenomenon of the torsional dynamies. It results from a set of approximate nonlinear differen equations which explain the fundamentals of nonlinaar torsional dynamies are verified by time-domain Simulation studies. The studies indicate that the range of instability of torsional is noticeably narrower than the one which is predicted by an ei-gin analysis method because of the Hopf bifurcation phenomenon.
