Abstract

While scraping remains a closely guarded technique for optimizing machine tool performance, quantifiable criteria haven't existed. This study utilizes a self-made machine to operate on commercial scraping workpieces and employs the new two-level three-body tribology theory to analyze the interface properties. Based on the analysis of the solid contact load ratio, contact temperature and plasticity index of the scraping interface, it is verified that the interface operates within the Stribeck curve's minimum friction region and most of deformation contact area is plastic. The extremely low skewness (S_sk) and the POP values achieve efficient dual-stage lubricant delivery on scraped surface. Online monitoring of performance degradation in scraped surfaces can be achieved by utilizing a combination of POP, S_q, and S_sk parameters.

基于两级三体接触模型的手部摩擦界面研究

虽然刮削仍然是一种严格保护的技术，以优化机床性能，量化的标准还不存在。本研究利用自制的机器对商业刮擦工件进行操作，并采用新的两级三体摩擦学理论对界面性能进行分析。通过对接触面固体接触载荷比、接触温度和塑性指标的分析，验证了接触面运行在Stribeck曲线最小摩擦区域内，大部分变形接触面积为塑性。极低的偏度（Ssk）和POP值在刮擦表面上实现了高效的双级润滑剂输送。通过结合使用POP、Sq和Ssk参数，可以实现对刮削表面性能退化的在线监测。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
