Growing economic and ecological pressure as well as increased technical requirements lead to higher power densities for the force-transmitting/force-locking components. The frequently used frictional connections (e.g. screw, flange, press-fit connections) offer a considerable increase potential in power density and wear resistance. For over 10 years, IKAT has been using model-based laboratory tests to investigate the coefficient of static friction (also: coefficient of friction or coefficient of friction) under static and dynamic conditions. dynamic load. The main areas of research are the characterization of friction-locking surfaces, friction-value-increasing applications, and Remedial measures against vibration wear (Fretting Wear).
The coefficient of static friction is to be understood as a system variable with a multitude of influencing parameters. In order to use existing potentials in friction-locking connections, an experimental investigation is indispensable. With the help of standardized Test methods on model samples are examined at the research centre with regard to their transfer behaviour in various tribological configurations. A main field of research is the synthesis of new design/selection tools for friction-enhancing measures (e.g. micro/laser structures, hard particles, coatings). for static and dynamic load cases. Furthermore, the suitability of remedial measures against vibration wear can be examined and evaluated with the aid of the test procedures.
