摘　　要：为了研究微小交叉凹槽图型表面对滑动摩擦性能的影响,采用销-盘摩擦副接触方式在石蜡油润滑下,对不同夹角的微小交叉凹槽图型表面进行摩擦试验,利用Stribeck曲线分析在不同试验条件下,不同夹角的微小交叉凹槽图型表面的摩擦特性,利用摩擦因数曲线图解析在不同载荷和滑动速度下,不同夹角的微小交叉凹槽图型表面的摩擦行为。结果表明,当试样表面微小交叉凹槽图型夹角为135°时,其减摩效果最佳,摩擦行为主要为混合及流体动力润滑状态下的摩擦。In order to study the influence of micro-crosshatch grooved surface pattern on the properties of sliding frictions, the tribologieal experiment was carried out on the surface of crosshatch groove pattern with different angles using pinon-disc lubricated by paraffin oil. The property of the surface of micro-crosshatch groove pattern with different angles was analyzed using stribeck curve under different testing conditions and the behavior of the surface of micro-crosshatch groove pattern with different angles using friction coefficient curve under different load and sliding velocity. The result shows the best effect of anti-friction occurs when crosshatch groove pattern with the angle of 135° and the friction behavior mainly is friction under mix and hydrodyniamic lubricating.
