Dynamic Friction Model for the Investigation of Stick‐Slip Oscillations.

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. [ABSTRACT FROM AUTHOR]
