| 摘 要： | 水润滑尾轴承在低速重载的工况下常出现严重磨损的情况.为降低润滑不良造成的尾轴承磨损,本文中通过观察铁犁木表面结构,分析其自润滑机理,设计出仿生微胶囊复合水润滑轴承材料.复合材料以高密度聚乙烯为基底材料,含基础油的仿生微胶囊为添加剂,采用共混的方式加工成型.使用CBZ-1船舶轴系摩擦磨损试验机研究了仿生微胶囊复合材料在不同试验工况下的摩擦性能.通过分析复合材料的磨损量和表面形貌参数,得出复合材料的磨损机理.结果表明:试验工况条件下,仿生微胶囊复合材料能够提升材料的摩擦学性能,其中当仿生微胶囊质量分数为3%时提升效果最明显.该研究为仿生水润滑材料的结构设计以及性能提升等提供试验依据.

| Abstract: | The severe abrasion wear of water-lubricated stern bearing usually occurs under the low-speed and heavy-duty working conditions. In order to reduce abrasion wear caused by undesirable lubrication, the water-lubricated stern bearing composites modified with biomimetic microcapsules were designed and its microstructure and the self-lubricated property of Lignum Vitae were investigated. High Density Polyethylene (HDPE) composites were prepared by blending HDPE powder and biomimetic microcapsules sealing with base oil. The tribological properties of the materials modified with biomimetic microcapsules were investigated using a CBZ-1 tribo-meter under different running conditions. The wear mechanisms of composites were obtained by analyzing the wear properties and surface morphology parameters. The results show that the biomimetic microcapsules improved the tribological properties of composites. The best tribological property is obtained for composite when microcapsules are 3%. This study provides the experimental basis to structural design and performance enhancement of the water-lubricated bearings. |
