摘要: 为了在外圆工件表面上研磨出具有随行波结构特征的鱼鳞表面结构,首先基于对自然界中鱼鳞表面形貌的特征分析,建立起外圆工件沿轴向排布的鱼鳞结构化表面数学模型;其次依据外圆研磨原理以及拓扑学理论,设计出用于研磨外圆鱼鳞表面的结构化拓扑油石;然后依据外圆研磨的磨粒运动轨迹,讨论实现外圆鱼鳞结构化表面研磨的边界条件;并对外圆研磨过程进行仿真模拟,获得了具有随行波结构的鱼鳞结构化表面。研究结果表明,利用所设计的结构化拓扑油石可以实现外圆鱼鳞结构化表面的研磨;改变研磨的振幅和频率,鱼鳞结构化表面的形状参数也会变化,但其表面拓扑属性不变。

Abstract: In order to lapping the structured fish scale surface with traveling wave structure on the surface of the cylindrical workpiece,firstly,based on the characteristic analysis of the surface morphology of fish scales in nature,the mathematical model of the structured fish scale surface of cylindrical workpieces arranged along axial direction was established. Secondly,according to the principle of lapping and topological theory,a structured topological whetstone for lapping fish scales on cylindrical surfaces was designed. Then,according to the abrasive grain movement trajectory for the cylindrical lapping,the boundary conditions for realizing the lapping processing of structured fish scale surface on the cylindrical workpiece were discussed. And the cylindrical lapping process was simulated to obtain the structured fish scale surfaces with traveling wave structure. The results show that cylindrical lapping for the structured fish scale surface can be realized by using the designed structured topological whetstone; by changing the amplitude and frequency of lapping,the shape parameters of the structured fish scale surface also change,but its surface topological properties do not change.

Key words: cylindrical lapping, fish scale surface, structured whetstone, topology mapping, traveling wave
