摘　　要：采用销-盘式摩擦试验机,在常温、常压及石蜡油润滑条件下,对不同密度的微凹半圆和圆图形织构进行摩擦特性试验.利用Stribeck曲线分析接触压力、图形密度、几何形状、滑动方向以及图形间距对摩擦性能的影响.结果表明,不同密度的微凹半圆图形织构,在A、B两个滑动方向下,摩擦系数的变化有明显的不同,但其变化会随着密度的增加而降低;微凹半圆图形织构的摩擦特性好于微凹圆形织构,当摩擦为A方向、密度为15%、间距为162μm时,微凹半圆图形织构的摩擦系数最小.Tribological experiment on the micro patterned half-circle and circle shape of different density was carried out using pin-on-disc friction pair at normal pressure and temperature and liquid lubricating. The effects of contact force, density, geometry, sliding direction and shape spacing on tribological characteristics were analyzed by using stribeck curve. The result shows that different density of micro patterned half-circle shape on A and B sliding direction, the variation of friction coefficient was obvious differences, with the in- crease of the density, the variation of friction coefficient decreased. The density was 15 %, the friction coeffi- cient of A sliding direction was smallest, and the friction properties of micro patterned half-circle shape was better than micro patterned circle shape, the best spacing was 162μm.
