SYSTEMS WITH QUASI-ZERO-STIFFNESS CHARACTERISTIC
Vibroprotective and impact-protective systems with elastic elements of passive type moving between two guides were investigated. These systems have force-displacement characteristics with a zone of quasi-zero-stiffness of the necessary length. The linear springs (in accordance with Hook’s law) and the pneumatic springs were used as elastic elements. The force-displacement characteristics with hysteresis loops resulting from the dry friction force were obtained. The amplitude-frequency characteristics for any case of force-displacement characteristic with rectangular loops of hysteresis were determined.
