| 摘 要： | 为减小轴承接触摩擦力及其对轴系振动的影响，本文基于磁力支承技术，设计一种全新的集成永磁支承力的复合式水润滑轴承，并对其摩擦学及动力学性能进行分析。研究发现：该设计能有效改善轴承润滑状态，最小液膜压力能提高79.6%，最大液膜压力减小幅度达75.7%，同时，艉轴稳定性保证在1-8之间，远大于其稳定性阈值0.02，该设计为未来船舶轴系振动控制提供一种新的思路。

| Abstract: | In order to reduce contact friction and its influence on shaft vibration, a new type of composite water lubricated bearing with permanent magnet supporting force is designed based on magnetic bearing technology, and its tribological and dynamic performances are analyzed. It is found that the design can effectively improve the lubrication state of the bearing. The minimum liquid film pressure is increased by 79.6% and the maximum liquid film pressure is reduced by 75.7%. At the same time, the stability of the stern shaft is still far greater than its threshold, and the value is between 1 and 8. This design provides a new idea for vibration control of ship shafting in the future. |
