In order to solve the contradiction between high load-carrying capacity and low natural frequency in designing ship water-lubricated stern bearing, an idea of independent design of load carrying and vibration reduction functions was proposed, and the squeeze film damper technology was innovatively introduced into a conventional water-lubricated stern bearing (CWSB) to form a water-lubricated damping stern bearing (WDSB). Harmonic responses of two bearings were calculated, and a dynamic characteristic experiment was carried out. The results show that the maximum displacement response (MDR) decreases with the increase in oil film clearance. With the increase in inner flange height, MDR increases first and then decreases. MDR decreases first and then increases with the increase in distribution angle. As rotation rate speeds, the difference between two bearings’ Root Mean Square (RMS) vibration amplitude remains unchanged. As load increases, relative reductions of two bearings’ maximum amplitude and RMS decrease. Amid a load of 0.2 MPa and a rotational speed of 200r/min, compared with CWSB, the maximum amplitude of WDSB in the vertical direction is reduced by about 71.8%, and the relative reduction in RMS is about 47.8%, which verifies the damping effect of WDSB is remarkable.

为解决船舶水润滑船尾轴承设计中高承载能力与低固有频率之间的矛盾，提出了独立设计承载和减振功能的思想，并创新性地引入了压膜减振器技术。传统的水润滑船尾轴承（CWSB），以形成水润滑阻尼船尾轴承（WDSB）。计算了两个轴承的谐波响应，并进行了动态特性实验。结果表明，最大位移响应（MDR）随着油膜间隙的增加而减小。随着内凸缘高度的增加，MDR首先增加，然后减少。MDR先下降，然后随着分布角的增加而增加。随着转速的加快，两个轴承的均方根（RMS）振动幅度之间的差异保持不变。随着负载的增加，两个轴承的最大振幅和RMS的相对减小量减小。与CWSB相比，在0.2 MPa的负载和200r / min的转速下，WDSB在垂直方向上的最大振幅降低了约71.8％，RMS的相对降低是约47.8％，这验证了阻尼WDSB的效果显着。
