  text: In turbomachinery, friction contacts are widely used to reduce dynamic stresses
    in turbine blades in order to avoid expensive damages. As a result of energy dissipation
    in the friction contacts the blade vibration amplitudes are reduced. In case of
    so-called friction dampers, which are pressed on the platforms of the blades by
    centrifugal forces, the damping effect can be optimized by varying the damper
    mass. This optimization can be done by means of a simulation model applying the
    so-called component mode synthesis and the Harmonic Balance Method to reduce computation
    time. It is based on the modal description of each substructure. In a real turbine
    or compressor blading great differences in the magnitude of the individual blade
    amplitudes occur caused by unavoidable mistuning of all system parameters like
    contact parameters and natural frequencies of the blades. It may happen that most
    of the blades experience only small stresses whereas a few blades experience critical
    stresses. Therefore, it is necessary to consider mistuning for all system parameters
    to simulate the forced response of bladed disk assemblies with friction contacts.
    For a mistuned bladed disk the complete system has to be modeled to calculate
    the dynamic response. In practice, usually the standard deviations instead of
    the distributions of the system parameters are known. Therefore, Monte-Carlo simulations
    are necessary to calculate the forced response of the blades for given mean values
    and standard deviations of the system parameters. To reduce the computational
    time, an approximate method has been developed and extended for small and moderate
    standard deviations of the system parameters to calculate the distribution and
    the envelopes of the frequency response functions for statistically varying system
    parameters, in the following called statistical mistuning. The approximate method
    is based on a sensitivity analysis and the assumption of a Weibull distribution
    of the vibration amplitudes of the blades. Both, the approximate method and the
    assumption of a Weibull distribution of the vibration amplitudes are validated
    by Monte-Carlo simulations. By these investigations the influence of different
    arrangements of the system parameters for given mean values and standard deviations
    of the vibration amplitudes of the blades can be determined, too. For the present
    investigations only a small influence of the arrangement of blades with respect
    to their natural frequencies has been observed. On the other hand, an intentional
    mistuning of the damper masses and the natural frequencies of the blades in a
    systematic way, in the following called systematic mistuning, can be investigated
    to reduce the amplitudes of the system. The simulation results of a systematic
    mistuning has been validated by a test rig with a rotating bladed disk assembly
    with friction dampers. The investigations show a good agreement between the simulations
    and the measurements but only a slight decrease of the maximum amplitudes in case
    of a systematic mistuning. Copyright {\copyright} 2004 by ASME

  text: Friction, especially friction of elastomers, can cause acoustic problems like
    noise, squeal and comfort drawbacks like vibrations and wear. Therefore, rubber
    friction affects the function of many products in technical applications, e.g.
    seals, belts and tires. It can be classified according to different physical phenomena
    like adhesion, hysteresis, cohesion and viscous friction, see [3]. The topic of
    this paper is hysteresis friction of rubber that is caused by the energy dissipation
    due to internal material damping during the process of deformation. The deformation
    itself occurs during the sliding of a rubber element across the micro-scaled asperities
    of a rough surface. In this paper, the sliding process of a rubber element over
    real surfaces is simulated in time domain and compared to experiments. ({\^A}{\copyright}

  text: During operation, the rotating blades of a gas turbine are subjected to centrifugal
    forces as well as fluctuating gas forces, resulting in blade vibrations. In addition
    to material damping, aerodynamical and blade root damping, underplatform dampers
    are widely used to increase the amount of damping and to decrease blade vibration
    amplitudes. The friction forces generated by the relative displacements between
    the underplatform damper and the blade platforms provide a significant amount
    of energy dissipation. In practice, a number of different underplatform damper
    designs are applied. Basically, these are wedge dampers with flat contact areas,
    cylindrical dampers with curved surfaces or asymmetrical dampers with both flat
    contact surfaces on one side and curved contact surfaces on the other. The latter
    damper type combines the advantages of both the wedge and the cylindrical damper
    by preventing the damper from pure rolling on the one hand as it has been observed
    for cylindrical dampers and on the other hand, avoiding a diverged plane area
    contact in case of a wedge damper, causing a damper lift-off. This paper will
    focus on the investigation of cylindrical and asymmetrical underplatform dampers.
    A comparison between measurements of rotating assemblies in Siemens PG gas turbines
    (V84.2, V64.3A and V94.3A(2)) under test and real operating conditions with cylindrical
    and asymmetrical underplatform dampers and the predictions of the developed theoretical
    model are presented. Special attention is paid to the frequency shift due to the
    application of an underplatform damper, since in particular for stationary gas
    turbines, in addition to the amplitude reduction, the accurate prediction of the
    resonance frequency is of major interest. Copyright {\copyright} 2004 by ASME

  text: Im Folgenden wird eine Berechnungsmethode vorgestellt, die es erlaubt, das
    räumliche Schwingungsverhalten eines elastischen Mehrkörpersystems (EMKS) mit
    Reibkontakten in rechenzeit- und speicherplatzsparender Form zu analysieren. Der
    von trockener Reibung und Mikroschlupf geprägte, nichtlineare Dämpfungsmechanismus
    in den Reibkontakten eines EMKS wird dabei realitätsnahe abgebildet. Die Plausibilität
    der mit der Methode gewonnenen Berechnungsergebnisse wird beispielhaft an einem
    einfachen EMKS, einem in Längsrichtung geteilten, einseitig eingespannten Balken
    gezeigt. Für den geteilten Balken werden die Frequenzgänge des Torsionswinkels
    um die Längsachse und der Auslenkung um die biegeweiche Achse berechnet.

  text: Friction damping devices such as underplatform dampers are widely used in
    turbomachinery applications to reduce blade vibration amplitudes. In this paper,
    a model is presented briefly to calculate the forced response of mistuned bladed
    systems with friction dampers. Some results will give an insight in the vibrational
    behavior of frictionally damped bladed disks and how the damping gain is affected
    by the damper properties.

  text: Numerical predictions of the forced vibration of a disc assembly including
    frictional effects between the shrouds are presented concerning engineering needs
    for the blade design process. Assuming a tuned disc assembly, numerical static,
    free and then forced vibration analyses of a shrouded turbine blade measured in
    the spin pit are performed systematically. For the excitation forces of an air
    jet evaluated from the fairly linear behavior of the experimental blade resonance
    peaks, the reliability of the proposed approach is validated through the very
    close agreement of the computed and measured resonant peaks. These resonant peaks
    demonstrate either a fairly linear behavior or a non-linear one like the jump
    effect of blade resonance amplitudes, or elastic impacts between the shrouds.
    Also, the damping performance for different contact configurations between the
    shrouds is numerically analyzed. These numerical results indicate that the shrouds
    generate higher frictional damping for small angles (0--30 deg) between the circumferential
    direction and the normal vector to the contact surface. Copyright {\copyright}

  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.
