著名学者佩特(Patir,N.)和郑绪云(Cheng,H.S.)从理论上推导出粗糙表面的纹理方向与弹流油膜厚度的关系。我们首次用实验方法验证了他们的理论。实验表明了横纹形貌的油膜厚度和接触率的优越性。笔者根据这个摩擦学的重要实验结论,提出对机加方法的建议,达到减少摩擦与磨损,提高经济效益的目的。 The well-known scholar Patir, N. and Cheng, H.S. Theoretically deduced the relationship between the texture direction of rough surface and the oil film thickness. For the first time, we validated their theory experimentally. The experimental results show the superiority of the oil film thickness and contact rate of the striae morphology. According to this important experimental conclusion of Tribology, the author puts forward the suggestion on machining method to reduce the friction and wear and improve the economic benefit.
