Finally, the torsion vibration nature frequency and torque amplitude factor of a rolling mill are calculated by using finite element method.
最后使用有限元法计算了某钢厂冷轧机主传动轴系的扭振固有频率和转矩放大系数。

The notable torsion effects of the surface ground motion above the alluvial valley are illustrated and the torsion effects become stronger as the frequency of the incidence is higher.
沉积盆地地表运动有强烈的扭转效应，并且此扭转效应随盆地变软和入射波频率的增高而增强。

The simulation shows that the first mode frequency for performance is near 1000Hz, which is much lower than that of the second mode. The displacement of mirror is caused by the torsion of beam.
