A full-size test rig of water-lubricated stern bearing (WSB) with an elevation adjustment device was built. High-precision wireless telemetry device obtained four film pressure signals. Six eddy current sensors were adopted to measure the axis orbit. The effect of bias load, rotational speed, and hull deformation on bearing lubrication characteristics are systematically studied. Experimental results showed the distribution lubrication characteristic of WSB at the axial direction. The WSB lubrication region can be divided into the three sub-regions in the middle and both ends of the bearing. Three lubrication sub-regions have different take-off speeds. Under the bias load, the negative pressure was found in the film pressure distribution. The hull deformation affects the position and area of each lubrication sub-region, changing the loads carried by the water film and asperity contact. Research results have a great contribution to WSB optimization structure design.

建造了带有高度调节装置的全尺寸水润滑艉轴轴承（WSB）试验台。高精度无线遥测装置获得了四个胶片压力信号。采用六个涡流传感器测量轴轨道。系统地研究了偏置载荷、转速和船体变形对轴承润滑特性的影响。实验结果表明WSB在轴向上具有分布润滑特性。WSB润滑区域可分为轴承中部和两端三个子区域。三个润滑子区域具有不同的起飞速度。在偏置负载下，薄膜压力分布出现负压。船体变形影响各润滑子区域的位置和面积，改变水膜和粗糙接触面所承载的载荷。研究成果对WSB优化结构设计有很大贡献。
