| 目的 提升水润滑轴承的摩擦学性能。方法 采用流固耦合的方法，对具有该复合型织构的水润滑轴承进行研究，将拥有仿生硅藻的多孔结构(矩形-半球型复合型织构)应用在轴承的高压区位置。分析具有矩形-半球型的复合织构的水润滑轴承在不同载荷、织构宽度以及间距的作用下，其摩擦学特性的变化。结果 通过与光滑轴承和单层织构轴承进行对比可知，随着载荷的增大，矩形-半球型复合型织构轴承的承载力随之增加，摩擦系数随之减小，并且有最大的轴承承载力和最小的摩擦系数。随着第一层及第二层织构宽度的增加，复合型织构轴承的承载力虽有复杂波动，但总体呈现上升趋势，摩擦系数呈现下降趋势。在间距较小时，复合型织构轴承的摩擦学性能更优，在间距一定的情况下，存在最优的织构个数，使得轴承的摩擦系数最小。结论 具有矩形-半球型复合织构的水润滑轴承适合在重载条件下工作，织构尺寸较大时，能产生较好的摩擦学性能;在间距较小时，复合型织构的摩擦学性能较为优异，且存在最优的织构个数。 |

| This paper is to improve the tribological properties of water lubricated bearings. In this paper, the fluid-structure coupling method is used to study the water-lubricated bearing with the compound dimple, and the porous structure with the bionic diatom (rectangular-hemispherical compound dimple) is applied to the high pressure region of the bearing. The tribological characteristics of water-lubricated bearings with the rectangular-hemispherical compound dimple under different loads, texture widths and spacing were analyzed. It can be seen from the experimental results by comparing with smooth bearing and single- layer textured bearing, it can be seen that with the increase of load, the bearing capacity of rectangular-hemispherical compound dimple bearing increases and the friction coefficient decreases, and it has the maximum bearing capacity and the minimum friction coefficient. With the increase of the width of the first layer and the second layer, the bearing capacity of the compound dimple bearing has a complex fluctuation, but generally presents a rising trend, the friction coefficient presents a declining trend. When the spacing is small, the tribological performance of compound dimple bearings is better. When the spacing is constant, there is an optimal number of dimples to minimize the friction coefficient of the bearing. Therefore, the water-lubricated bearings with the rectangular-hemispherical compound dimple are suitable for working under heavy load conditions. When the dimple size is large, it can produce better tribological properties. When the spacing is small, the tribological properties of compound dimple are better, and there is an optimal number of dimples. |
