Research on the Rolling Theory of Sinusoidal Motion on Structured Surfaces

  • 摘要: 结构化表面因其优异的减阻和润滑性能,已成为改善机械装备表面功能的重要手段。为了在外圆工件表面上加工出结构化表面,该文提出了一种基于钢珠正弦运动滚压的制造方法。为实现该方法,建立了正弦滚压运动模型,并通过计算机仿真分析,探讨了滚压运动参数对结构化表面形态的影响规律。研究结果表明,所设计的钢珠正弦运动滚压方法能够有效实现外圆结构化表面的加工。在轴向进给滚压过程中,通过调节振动频率、振幅及轴向进给速度,可以改变结构化表面的特征;合理选择振动频率、振幅和轴向进给速度,则能够获得均匀的网纹结构。

     

    Abstract: Structured surfaces, owing to their excellent drag-reducing and lubrication properties, have become an important means of improving the functional performance of mechanical equipment surfaces. To fabricate structured surfaces on the outer cylindrical surface of workpieces, this paper proposes a manufacturing method based on roller burnishing with sinusoidal motion of a steel ball. To realize this method, a sinusoidal burnishing motion model was established, and computer simulations were conducted to analyze the influence of burnishing motion parameters on the morphology of the structured surface. The results show that the proposed steel-ball sinusoidal burnishing method can effectively achieve the fabrication of structured surfaces on outer cylinders. During the axial feed burnishing process, the characteristics of the structured surface can be modified by adjusting vibration frequency, amplitude, and axial feed rate; by selecting appropriate vibration frequency, amplitude, and feed rate, a uniform mesh-like structure can be obtained.
