Summary: | The stick-slip behaviour of elastomers plays an extremely important role under service relevant loading conditions in many tribological applications. In a number of practical situations, the friction instability (stick-slip) causes negative influence on the sliding performance of various components (e.g. seals, wipers or dampers). To characterise the stick-slip behavior of polymers a rotation based test set-up was used on an axial/torsional dynamic testing machine (BOSE 3200AT) with the ring-on disc specimen configuration. This paper describes under which conditions stick-slip occurred (for both monotonic and dynamic loading) and how to use these results to make a more efficient material selection. In that case the load, velocity and amplitude dependencies were summarized in form of diagrams as a 'Running condition stick-slip map'. |
