The optimization of lubricated sealing systems with respect to the stick-slip effect requires a friction model that describes the complex friction behavior in the lubricated contact area. This paper presents an efficient dynamic friction model based on the Stribeck curve, which allows to investigate the influencing parameters through finite element (FE) simulations. The simulation of a tribometer test using this friction model proofs that the model correlates well with the tribometer test results. It is shown that the system stiffness has a significant influence on the stick-slip tendency of the system.

研究粘滑振荡的动态摩擦模型

针对粘滑效应优化润滑密封系统需要一个摩擦模型来描述润滑接触区域中的复杂摩擦行为。本文提出了一种基于 Stribeck 曲线的高效动摩擦模型，该模型允许通过有限元 (FE) 模拟研究影响参数。使用此摩擦模型模拟摩擦磨损试验证明该模型与摩擦磨损试验结果密切相关。结果表明，系统刚度对系统的粘滑倾向有显着影响。
