摘要: 粗糙表面在自然界普遍存在。在研究表界面现象时,粗糙表面往往是重要的输入信息。实际测量和数值仿真是获取粗糙表面的两种常用方法。与实际测量相比,数值仿真无需昂贵的测量设备和大量机时,即可根据给定的表面特征信息高效地批量生成粗糙表面。目前,表面仿真已有近五十年的发展历史,基于不同表面形貌特征形成了采用多种表面特征参数的多种仿真方法,在摩擦学研究中应用广泛。梳理和总结表面仿真方法利于方法的高效、准确应用以及进一步发展。考虑到表面仿真方法与表面形貌特征及其表征参数密切相关,为了系统全面地综述表面仿真方法,首先介绍与表面仿真相关的形貌特征表征方法及特征参数。随后,以不同特征为线索对相应的表面仿真方法的原理、算法、优缺点进行梳理,初步提出了方法选用建议,并整理了其在摩擦学研究中的典型应用,最后展望了未来粗糙表面仿真的可能研究方向。

Abstract: Rough surfaces are ubiquitous in nature. Rough surfaces are often a vital input when studying surface-interface phenomena. Measurement and numerical simulation are two widely used methods for obtaining rough surfaces. Compared with measurement, numerical simulation can efficiently generate rough surfaces in batches based on surface feature information without expensive measurement equipment and much time. Surface simulation has a development history of nearly fifty years. Various simulation methods using various surface feature parameters have been developed based on different surface features, which are widely used in tribology research. Sorting out and summarizing surface simulation methods is conducive to the efficient and accurate application and further development of the method. Considering that surface simulation methods are closely related to surface features and their characterization parameters, to systematically review surface simulation methods, the feature characterization methods and characteristic parameters related to surface simulation are first introduced. Then, the principle, algorithm, advantages, and disadvantages of the corresponding surface simulation methods are sorted out with different characteristics as clues, suggestions for method selection are proposed, and their typical applications in tribology research are sorted out. Finally, the possible research directions of rough surface simulation in the future are discussed.

Key words: rough surfaces, numerical simulation, methods comparison, tribological application
