摘要: 表面作为零部件的"指纹",其科学性是开展后续润滑、接触、摩擦磨损、监测控制等研究的基础。现有学者多从单层表面视角出发理解表面,而忽视了双工序、磨损等表面存在的双高斯分层特征。少量学者受到双工序表面加工制造过程的启发,提出了双高斯分层表面理论,并成功拓展至磨损表面的研究。从表面表征仿真、润滑接触、摩擦磨损、监测控制四个方面归纳总结了国内外有关双高斯分层表面理论的研究工作,特别关注该理论在机械密封领域的应用,进而提出了后续可深入探讨的双高斯研究方向,以期为机械密封的设计与研究提供理论和工程指导。

Abstract: Surface, serving as the fingerprint of a component, is the basis of the following investigations on lubrication, asperity contact, wear and friction, monitoring and controlling, etc. Researchers usually understand a surface from the perspective of a classical single-stratum surface, while ignore the bi-Gaussian stratified characteristic exists in a two-process or worn surface. Some researchers proposed a bi-Gaussian stratified surface theory from the processing and manufacturing of two-process surfaces, and then extended to worn surfaces. In the present study, a review of bi-Gaussian-stratified-surface-theory works is given with respect to surface characterization and simulation, lubrication and contact, wear and friction, and monitoring and controlling, which particularly focuses on the field of mechanical seals. The interesting bi-Gaussian issues those can be further explored are also discussed. It will benefit the design and analysis of mechanical seals.

Key words: acoustic emission, asperity contact, lubrication, mechanical seal, surface topography, wear and friction
