Impact of Propeller Elasticity on Longitudinal Vibration Characteristics of Propulsion Shafting

  • 摘要: 针对当前研究中多数模型未考虑螺旋桨弹性的问题,建立梁-弹簧振子构成的简化螺旋桨模型,分析螺旋桨不同简化方式对轴系纵向振动计算结果的影响,并进一步研究螺旋桨伞状模态频率与轴系纵振模态频率的关系对轴系纵振的影响。结果表明:螺旋桨伞状模态在轴系纵向振动中有明显体现;螺旋桨一阶伞状模态主要影响轴系前两阶纵向振动频率处的振动峰值;螺旋桨二阶伞状模态主要影响轴系第二阶纵向振动频率处的振动峰值;螺旋桨二阶伞状模态频率与轴系反共振频率接近时,能有效降低推力轴承处的振动功率流。
