Strong vibrations are often undesired in mechanical engineering. They can cause noise and wear disturbing normal
operation conditions of a system. Thus a lot of efforts are applied for quenching undesired vibrations. However, the complete
elimination of vibrations is neither possible nor objected from the technical point of view. It is usually sufficient to limit the
vibration amplitudes to a certain level acceptable for specific operation conditions. There are various devices and
approaches used for limiting vibration amplitudes. Dynamic dampers and viscoelastic elements are only two of the most
usual ones. However, viscous elements are sometimes difficult to use. It is the case for example in automotive clutches and
brakes because of high temperatures which can reach 600 1C in the clutches and 1000 1C in the brakes. Thus dry friction
dampers are used in these applications
