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: 'Several positioning tasks demand translatory drive instead of rotary motion.
To achieve drives that are capable e.g. to drive the sunroof of a car or to lift
a car''s window, multiple miniaturized motors can be combined. But in this case
many other questions arise: the electromechanical behavior of the individual motors
differs slightly, the motor characteristics are strongly dependent on the driving
parameters and the driven load, many applications need some extra power for special
cases like overcoming higher forces periodically. Thus, the bundle of motors has
to act well organized and controlled to get an optimized drive that is not oversized
and costly.'

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.
