EN The paper is focused on study of new type of vibration control damper which has been designed, machined, assembled, and calibrated by authors. In typical oil dampers, attenuation force is generated by fixed orifices, where oil passes from one chamber to another. More advanced designs include variable orifices, where it is possible to regulate precisely flow area, e.g., by proportional valve. Thus, these solutions are so-called valve mode, also very popular in whole group of magnetorheological dampers. Another known in engineering type of dampers is based on viscous friction. Steel rood passed through cylinder head, where interference fit creates movement resistance. This paper proposes novel design of damper, where in order to control damping force, simple direct current motor and special mechanism, similar to wedge, has been proposed. To perform basic research on damper’s characteristics, special test stand was designed. Crankshaft mechanism was used to generate reciprocating movement. During tests, one end fixed damper was connected to slider by force transducer. To describe phenomenon of variable damping force, force–displacement and force–velocity characteristics have been registered and described.
