Originální abstrakt

This paper is focused on magnterorheological (MR) dampers and their critical parts in terms of damper`s durability, which seems to be a piston-rod seal. An option to reduce the wear is to choose the proper material for that purpose. The wear measurements were conducted in an accelerated and simplified mode in a modified pin-on-flat (cylinder-on-flat) configuration, which was supposed to be more suitable for laboratory testing than original configurations. Suitable commercial materials for seals, like PTFE, NBR, SBR, and polyurethanes, were tested and compared in commercial MR fluid MRF-132DG by LORD Corporation. It turned out that material H-PU95FDA had had the biggest wear resistance from all tested materials and therefore it was the most suitable material for durable seals, while PTFE seals are expected to be suitable in non-durable applications with low frictional forces.
