| 摘 要： | 共振转换器是控制轴系纵向振动的重要装置。利用该装置内的工作流体改变轴系纵向刚度和阻尼,达到减振的目的。减振装置内的流体压强随轴系纵向载荷而改变,从而影响共振转换器的减振效果。对安装共振转换器的轴系纵向振动有限元模型,考察减振装置的等效减振参数与内部流体工作压强的非线性关系。基于Wilson-θ法在时域内求解推力轴承基座处的纵向加速度响应,通过傅里叶变换在频域内分析轴系纵向振动特性,研究减振装置内的流体压强变化对减振效果的影响,并讨论结构尺寸与减振效果之间的关系。

| Abstract: | Resonance changer is an effective equipment to control longitudinal vibration of marine shafting.Due to the working fluid in the damping device,the longitudinal stiffness and damping of the shafting system is changed and results in vibration attenuation.For the alternation longitudinal load of the marine shafting,the working pressure in the device changes and impacts on the vibration damping effect of resonance changer.The longitudinal vibration model of ship shafting system is established based on the fini... |
