In this article a passive system, which exploits the properties of the Coulomb friction and leads to high affordability of controlling shocks and vibrations by means of cheap devices is presented. The friction force developed by the proposed device is dependent on the motion stroke by convenient modulation of contact force between the elements of friction coupling. For providing the system self-centring properties or necessary vertical load capacity, coil springs can be incorporated into the device structure. The device hysteresis characteristic can be simply adjusted to comply with requirements of the considered application. A general mathematical model of device dynamic behaviour is developed and applied to shock and vibration isolation systems. The article presents a novel passive device with variable friction which hysteresis force-displacement characteristics have “butterfly” shape, achieved by appropriate design of friction coupling. This shape of hysteresis loops can mitigate the drawbacks of constant friction devices. The schematic of mechanical systems to analyse the dynamic behaviour of shock and vibration isolation systems with variable friction device are shown.
