This study experimentally investigates the influence of cavitation effect caused by surface texture on the lubrication performance of friction pairs. In order to verify and research the cavitation phenomenon induced by surface texture, cavitation images are collected by visual experimental apparatus. The results show that the surface texture will induce the cavitation of the lubricating oil under certain speed and load conditions, gas bubbles will be generated at the outlet of the dimples, and the cavitation will affect the lubrication performance of the friction pair. When the texture depth is close to the oil film thickness, it has the best effect in terms of inducing cavitation and promoting lubrication. And it is found in the experiments when area density of texture is 8% and the square dimples are arranged at inlet area of the sample, the best effect of the surface texture can be obtained.

摩擦副表面织构空化效应的观察与实验研究

本研究实验研究了表面纹理引起的气穴效应对摩擦副润滑性能的影响。为了验证和研究由表面纹理引起的空化现象，通过视觉实验设备收集空化图像。结果表明，在一定的速度和负载条件下，表面纹理会引起润滑油的气蚀现象，在凹坑的出口处会产生气泡，并且这种气蚀现象会影响摩擦副的润滑性能。当纹理深度接近油膜厚度时，在引起气蚀和促进润滑方面具有最佳效果。在实验中发现，当纹理的区域密度为8％，并且在样品的入口区域布置了方形凹痕时，
