| Abstract |
This study aims to investigate the contact performance of non-Gaussian rough surfaces under mixed lubrication conditions, with a particular emphasis on the normal dynamic contact stiffness and damping characteristics. The research employs statistical analysis and modeling techniques to analyze non-Gaussian rough surfaces and combines them with the theory of elastic-plastic fluid dynamic lubrication. The objective is to examine the variations in stiffness and damping during the contact process. Numerical simulations are conducted to explore the impact of factors such as normal dynamic load, lubricant viscosity, operating speed, vibration frequency, vibration force, and non-Gaussian roughness on the normal dynamic contact stiffness and damping at the mating interface. The findings of this research provide valuable insights in advancing the design, analysis, and optimization of sliding guide performance in the field of machine tools. |
