摘要 为研究沟槽型织构角度及排布形式对接触表面摩擦学性能的影响,通过有限元分析软件对不同角度及排布形式的沟槽型织构进行数值模拟,利用YLP-20型激光加工系统在不锈钢圆盘表面加工沟槽型织构,并利用UMT-2摩擦磨损仪在旋转条件下进行摩擦实验。结果表明:沟槽型织构的数值模拟结果与实验结果基本吻合,加工有织构的摩擦副其摩擦学性能得到改善,且不同角度及排布形式的沟槽型织构对摩擦副的摩擦学性能影响不同,即当摩擦速率小于300r/min时0°平行织构的摩擦因数较小;摩擦速率大于300r/min时90°平行织构有更好的减摩能力,故应用中要根据不同工况条件选择不同排布形式的沟槽型织构。

Abstract:In order to study the influence of the angle and arrangement forms of micro-grooves on the tribological performance of the contact surface, the finite element analysis software was used to simulate the grooved textures with different angles and arrangements. The YLP-20 laser processing system was used to process grooved texture on stainless steel disk surfaces, and the Tribometer (UMT-2) was also used to conduct tribological test under the condition of rotation. The results show that the numerical simulation values are basically consistent with experimental results of grooved textures, and the tribological performance of the friction pairs with textures is also improved. The grooved textures with different angles and arrangement forms have different influence on tribological performance of friction pairs. When the friction velocity is less than 300r/min, the parallel texture with 0° has smaller friction coefficients. While the friction velocity is larger than 300r/min, the parallel texture with 90° has a better ability of reducing friction. Therefore, different grooved textures should be chosen according to operation conditions.
