When other conditions are same, the great excitedforce frequency, the better isolation effect.
在其他条件相同时，激励频率越大，隔振效果越好。

According to coupling principle and excitedforce of shafting system, a model of coupled torsional-axial forced vibration can be constructed.
根据刚度耦合原理，并考虑轴系强迫激励进而建立了扭纵耦合强迫振动模型。

It is verified by means of model test that the ship vibration is caused by the propeller-excitedforce, which is generated by the propeller running in the non-uniform stern flow field.
