  text: In forced systems with cyclic symmetry localization can occur due toparameter
    uncertainties. Often, Monte-Carlo simulations are used to findregions, where the
    system response is sensitive to parameteruncertainties. These simulations require
    a large computation time.Therefore, an approximate method to calculate the envelopes
    of thefrequency response functions is developed in this paper. An example of anonlinear
    system with cyclic symmetry is a bladed disk assembly withfriction dampers. Friction
    dampers can be installed underneath the bladeplatforms of turbine blades. Due
    to dry friction and the relative motionbetween blades and dampers, energy is dissipated,
    which results in areduction of blade vibration amplitudes. By optimizing the mass
    of thefriction dampers, the best damping effects are obtained, which lead toan
    increase in the reliability of the turbine. In this paper, thecalculated response
    of a mistuned bladed disk assembly with frictiondampers is discussed. An approximate
    method is developed to calculatethe envelopes of the corresponding frequency response
    function forstatistically varying eigenfrequencies of the blades. Regions wherelocalization
    can occur with a high probability, are calculated by thismethod.

  text: The paper deals with cyclic periodic structures modelling bladed disk assemblies
    of blades with friction elements for vibration damping. These elements placed
    between adjacent blades reduce the vibration amplitudes by means of dry friction
    resulting from centrifugal forces acting on the elements and relative displacements
    of the blades. However, the application of these friction elements results in
    an additional dynamical coupling which together with mistuning of some system
    parameters (e.g., blade eigenfrequency or contact parameters) may cause localization
    of vibration. In the present paper a linear approximation of such a system is
    investigated. The structure composed of cyclic periodic cells modelled each as
    a clamped-free beam interacting with each other by means of viscoelastic elements
    of complex stiffness is applied for dynamic system analysis. In case of free vibrations
    as well as in case of steady-state dynamic response to a harmonic pressure field,
    a perfect periodic structure and the structures with periodically mistuned parameters
    (blade eigenfrequencies and contact parameters) are studied. Some regularities
    in the dynamic response of the systems with mistuning have been noticed. Despite
    the fact that only a linear approximation has been used, the results and conclusions
    can be applied for models which describe the blade interaction in a nonlinear
    way.

  text: the vibration amplitudes of bladed disk assemblies can be reduced significantly
    by means of friction damping devices such as shrouds, damping wires and interblade
    Friction dampers. in practice, interblade Friction dampers are applied in rotating
    arrangements with various geometries showing curved or flat surfaces like so-called
    wedge-shaped dampers. this paper is focusing on a computation method to predict
    the dynamical behaviour of turbine blades with Friction dampers including both,
    curved and wedge-shaped dampers with hertzian and non-herutian contact conditions,
    respectively. the presented computation method uses a 3d contact model to calculate
    the contact forces, including normal and tangential stiffnesses, roughness and
    microslip effects. the relative displacements in the contact area can be expressed
    by means of 6 dof of the blade platforms and 6 rigid body dof of the damper including
    translational and rotational displacements. the relative displacement of the Friction
    damper with respect to the adjacent blades can be derived from the contact kinematics
    of the blade-damper-blade system and the equations of motion of the Friction damper.
    thus, the model can be applied to investigate spatial motions of the bladed disk
    assembly including bending and torsional vibrations. a comparison of different
    Friction damper designs with respect to an optimal damper geometry and damper
    mass is presented. the advantages and disadvantages of each design will be discussed.
    experimental results are shown to validate the developed computation method.
