  text: The contact between viscoelastic materials e.g. elastomers and a rough surface
    leads to a special friction characteristic, which differs greatly in its properties
    comparing to other materials like metals. In practice, this friction combination
    occurs for example in the tire-road contact, or in the use of rubber gaskets.
    Due to the frictional forces a system is significantly influenced in its vibrational
    properties. The friction force is composed of two main components adhesion and
    hysteresis. The adhesion results from molecular bounds between the contact partners,
    while the deformation of the viscoelastic material by the roughness of the counter
    body leads to power loss. This internal friction results in an additional frictional
    force, which is described by the hysteresis. To simulate the frictional behaviour
    of elastomers on rough surfaces and thus to determine the energy dissipation in
    contact, it is necessary to develop a mechanical model which considers the roughness
    of the contact partners, as well as dynamic effects and the dependence on normal
    pressure and sliding speed. The viscoelastic material behaviour must also be considered.
    The contact between two rough surfaces is modelled as a rough rigid layer contacting
    a rough elas- tic layer. The elastic layer is modelled by point masses connected
    by Maxwell-elements. This allows the viscoelastic properties of the elastomer
    to be considered. The behaviour of whole system can be described by equations
    of motion with integrated constraints. The degrees of freedom of the model depends
    on the varying contact conditions. A point mass not in contact has two degrees
    of freedom. A point mass in contact moving along the roughness path can be described
    by only one degree of freedom. For each Maxwell-Element also an inner coordinate
    and thus a further degree of freedom is needed. Because of varying contact conditions
    dur- ing the simulation, the simulation interrupts in case the contact conditions
    change. Then the equations of motions are adapted with respect to the contact
    constraints. As a result of the simulation one obtain the energy dissipation and
    thus the friction char- acteristic during the friction process. It is possible
    to use these results in three dimensional point-contact elements in order to model
    contact surfaces on lager length scales.
