摘　　要：船舶螺旋桨的偏振对螺旋桨叶片的寿命和船体尾部的振动情况有着重要的影响,为了减少螺旋桨偏振、提高其抗冲击稳定性,运用理论分析和实验室模拟测试手段,研究了螺旋桨偏振发生的频段,提出了防范措施,具有广阔的推广应用前景。　Deflective vibration of ship propeller has an import impact on vibrating of the tail of ship and life-span of propeller.To diminish deflective vibration and improve stability of shock resistance,method of theory and simulation test were done,and frequency range of deflective vibration of propeller happening was studied.Finally,countermeasure was put forward,and the method illustrates a good prospect of application and extension.
