Experimental Study On Stiffness And Damping Of
Machined Surfaces In Contact
Author(s)
Konrad Konowalski & Kami Grudzinski
Abstract
The paper presents a test rig designed for studying contact stiffness of flat machined surfaces.
The cast-iron samples employed had rated surfaces A= 56.5 cnf. Defined were the
relationships of comparative contact displacement versus surfaces pressures under static and
dynamic loads. Basing upon the data obtained, determined was the effect of mean surfaces
pressures also amplitudes and frequency of load, upon stiffness as well as upon vibration
energy dispersal. The outcome of the experimental study served in defining dynamic contact
stiffness values equivalent for Kelvin-Voigt model also indefining comparative factors of
vibration energy dissipation.
