Abstract

AbstractFriction and wear seriously affect the efficiency and life of the machine device. The dynamic pressure lubrication and friction properties of the surface are improved by surface texture technology, which plays an extremely important role in reducing friction and wear. In order to maximize the hydrodynamic lubrication and friction reduction performance of surface texture, a Tesla valve surface texture is proposed in this paper. The oil film bearing capacity and wall friction of Tesla valve texture through CFD(Computational Fluid Dynamics) fluid simulation. Cylindrical rolls with Tesla valve texture are prepared by using the laser processing technology, and comparative friction wear tests are conducted. The results show that the lubrication performance of Tesla valve texture are 4 times higher than those of the non-texture; The friction coefficient and wear loss of the cylindrical rolls with Tesla valve texture are, respectively, 39.7% and 66.7% lower than those of the cylindrical rolls without texture. Tesla valve texture effectively improves the dynamic pressure lubrication and friction in the cylindrical rolls.Keywords: Tesla valveSurface textureDynamic pressure lubricationFriction reduction performanceDisclaimerAs a service to authors and researchers we are providing this version of an accepted manuscript (AM).

特斯拉阀织构圆柱辊流体动力润滑及减摩性能研究

摘要摩擦磨损严重影响机械装置的工作效率和使用寿命。通过表面织构技术改善了表面的动压润滑和摩擦性能，对减少摩擦磨损起着极其重要的作用。为了最大限度地发挥表面织构的流体动力润滑和减摩性能，本文提出了一种特斯拉阀表面织构。通过CFD(Computational Fluid Dynamics)流体模拟研究了特斯拉阀织构的油膜承载能力和壁面摩擦。采用激光加工技术制备了具有特斯拉阀织构的圆柱卷，并进行了对比摩擦磨损试验。结果表明:特斯拉阀织构的润滑性能是非织构的4倍;具有特斯拉阀织构的圆柱辊的摩擦系数和磨损量分别比无织构圆柱辊低39.7%和66.7%。特斯拉阀织构有效地改善了圆柱辊的动压润滑和摩擦。关键词:特斯拉阀门表面纹理动压润滑减摩性能免责声明作为对作者和研究人员的服务，我们提供此版本的接受稿件(AM)。在最终出版版本记录(VoR)之前，将对该手稿进行编辑、排版和审查。在制作和印前，可能会发现可能影响内容的错误，所有适用于期刊的法律免责声明也与这些版本有关。
