Advances in Optimization Design and Application of Textured Surfaces

作为改善摩擦表面界面性能的有效途径,表面织构现已成为摩擦学领域和表面工程领域的研究热点之一,但是表面织构的机理研究以及织构优化设计体系尚未完善。首先从表面织构的承载机理和抗磨机理研究出发,揭示了织构表面润滑改善原因。其次从表面织构的形状优化、分布优化和目标优化算法三个方面总结了表面织构的优化设计体系,综述了表面织构优化设计的研究进展。最后介绍了表面织构在工业应用的研究现状。表面织构的性能受结构参数及分布参数影响较大,而多参数协同优化设计为解决该问题的有效方法。随着不断深入地对承载机理和抗磨机理、优化体系中关键技术以及不同领域应用的研究,以"机理-优化-应用"为思路的表面织构理论与设计体系有望形成。

As an effective way to improve the interface properties of friction surfaces,surface texture technology has become one of the research hot spots in the fields of tribology and surface engineering.However,the investigations of mechanisms and surface texture’s summary of optimization design demands improvement.Firstly,the reasons for the lubrication improvement on the textured surfaces are revealed based on the study of the textured loading capacity mechanisms and anti-wear mechanisms.Then,the textured optimization design system is summarized from three aspects:optimization of textured shapes,optimization of textured distributions and objective optimization algorithms.And the research progress of textured optimization design is reviewed.Finally,researches on the applications of textures in engineering industry are reviewed.The textured performances are considerably affected by their structural and distribution parameters,and the multi-parameter collaborative optimization design has gradually become the main method to solve above problems.With the continuous deepening investigations of textured loading capacity mechanisms and anti-wear mechanisms,the key technologies of textured optimization system and the textured application research in different fields,it is expected to form a textured theory and design system based on the idea of"mechanism-optimization-application"gradually.
