torsional vibration frequency

The calculation result indicates that the torsional vibration frequency will avoid from power frequency and multiple frequency.

计算结果表明，机组扭振频率避开了工频与倍频，轴系不会因共振而破坏。

The continuous model is adopted in the torsional vibration frequency and resonance of shaft system, the lumped parameter equivalent applied in the sub-synchronous resonance.

轴系扭振频率和响应计算采用连续质量模型，次同步谐振特性分析采用集中质量模型。

Secondly, the relationship between rotary inertia coefficient, torsional stiffness, transmission gearbox and torsional vibration frequency is analyzed on the basis of the design model.

其次，在双质量飞轮设计模型的基础上，分析了双质量飞轮转动惯量系数、扭转刚度、变速器与系统扭振频率的关系。
