text: Self-optimizing mechatronic systems offer possibilities well beyond those
of traditional mechatronic systems. Among these is the adaptation of the system
behavior to the current situation. To do so, they are able to choose from different
working points, which are pre-calculated using multiobjective optimization and
are thus Pareto-optimal with regard to the chosen objective functions. In this
contribution, a method is presented that allows to continuously control the system
degradation by adapting the behavior of a selfoptimizing system throughout its
complete lifetime. The current remaining useful lifetime is estimated and then
related to the spent lifetime and the desired useful lifetime. Using this information,
a reliability-related objective is prioritized using a closed-loop control, which
in turn is used to determine the working point of the self-optimizing system.
This way, the desired useful lifetime can be achieved. To exemplify the setup
of the controller structure and to demonstrate the adaptation of the system behavior,
a dynamic model of a clutch system is used. It can be seen that the closed loop
controller is able to correct for external perturbations, such as changed requirements,
as well as changed system parameters. This way, the modeled system is able to
achieve the desired lifetime reliably.

text: Selbstoptimierende mechatronische Systeme bieten die Möglichkeit, ihr Verhalten
an geänderte Umgebungsbedingungen anzupassen. Dazu werden beispielsweise redundante
Strukturen genutzt, Reglerparameter angepasst oder Regelstrategien umgeschaltet.
Dies kann auch genutzt werden, um die Zuverlässigkeit des Systems zu steigern.
Zugleich entstehen aber durch die gesteigerte Komplexität dieser Systeme zusätzliche
Risiken. Um sicherzustellen, dass das System dennoch die gestellten Anforderungen
bezüglich der Zuverlässigkeit erfüllt, ist eine Modellierung des Gesamtsystems
und anschließende Zuverlässigkeitsbewertung notwendig. Dies ist aufgrund der situationsabhängigen
Verhaltensanpassung und des nicht intuitiv vorhersehbaren Verhaltens jedoch nicht
mit klassischen Verfahren möglich. Ein Modellierungsverfahren, das diese Eigenschaften
abbilden kann, ist LARES (LAnguage for REconfigurable dependable Systems). Die
Anwendung von LARES zur Bewertung der Zuverlässigkeit eines selbstoptimierenden
Systems wird anhand des Feder-Neige-Moduls gezeigt. Es ist eine Baugruppe der
Fahrzeuge eines innovativen Bahnsystems, der RailCabs. Das Feder-Neige-Modul dient
dazu, unerwünschte Schwingungen des Fahrzeugaufbaus zu minimieren. Mit LARES können
die Hardware-Komponenten des Systems, ihre in Abhängigkeit von der aktuellen Situation
veränderten Belastungen sowie die nicht-deterministische Verhaltensadaption modelliert
werden.

text: 'A piezoelectric energy harvester is an electromechanical device that converts
ambient mechanical vibration into electric power. Most existing vibration energy
harvesting devices operate effectively at a single frequency only, dictated by
the design of the device. This frequency must match the frequency of the host
structure vibration. However, real world structural vibrations rarely have a specific
constant frequency. Therefore, piezoelectric harvesters that generate usable power
across a range of exciting frequencies are required to make this technology commercially
viable. Currently known harvester tuning techniques have many limitations, in
particular they miss the ability to work during harvester operation and most often
cannot perform a precise tuning. This paper describes the design and testing of
a vibration energy harvester with tunable resonance frequency, wherein the tuning
is accomplished by changing the attraction force between two permanent magnets
by adjusting the distance between the magnets. This tuning technique allows the
natural frequency to be manipulated before and during operation of the harvester.
Furthermore the paper presents a physical description of the frequency tuning
effect. The experimental results achieved with a piezoelectric bimorph fit the
calculated results very well. The calculation and experimental results show that
using this tuning technique the natural frequency of the harvester can be varied
efficiently within a wide range: in the test setup, the natural frequency of the
piezoelectric bimorph could be increased by more than 70\%.'

text: Piezoelectric structures are nowadays used in many different applications.
A better understanding of the influence of material properties and geometrical
design on the performance of these structures helps to develop piezoelectric structures
specifically designed for their application. Different equivalent circuits have
been introduced in the literature to investigate the behaviour of piezoelectric
transducers. The model parameters are usually determined from measurements covering
the characteristic frequencies of the piezoelectric transducer. This article introduces
an analytical technique for calculating the mechanical and electrical equivalent
system parameters and characteristic frequencies based on material properties
and geometry for a cantilever bimorph structure. The model is validated by measurements
using a cantilever bimorph and fits the experimental results better than previous
models. The model gives a full set of piezoelectric transducer parameters and
is therefore well suited for further theoretical investigations of piezoelectric
transducers for different applications. The results also show that even small
manufacturing tolerances have a considerable effect on the system parameters and
characteristic frequencies. This might lead to intolerable deviations, especially
in dynamic applications and should be avoided by careful design and production.

text: To optimize the ultrasound irradiation for cavitation based ultrasound applications
like sonochemistry or ultrasound cleaning, the correlation between cavitation
intensity and the resulting effect on the process is of interest. Furthermore,
changing conditions like temperature and pressure result in varying acoustic properties
of the liquid. That might necessitate an adaption of the ultrasound irradiation.
To detect such changes during operation, process monitoring is desired. Labor
intensive processes, that might be carried out for several hours, also require
process monitoring to increase their reliability by detection of changes or malfunctions
during operation. In some applications cavitation detection and monitoring can
be achieved by the application of sensors in the sound field. Though the application
of sensors is possible, this necessitates modifications on the system and the
sensor might disturb the sound field. In other applications harsh, process conditions
prohibit the application of sensors in the sound field. Therefore alternative
techniques for cavitation detection and monitoring are desired. The applicability
of an external microphone and a self-sensing ultrasound transducer for cavitation
detection were experimentally investigated. Both methods were found to be suitable
and easily applicable.

text: 'The rapid development of communication and information technology opens up
fascinating perspectives, which go far beyond the state of the art in mechatronics:
mechatronic systems with inherent partial intelligence. These so called self-optimizing
systems adapt their objectives and behavior autonomously and flexibly to changing
operating conditions. On the one hand, securing the dependability of such systems
is challenging due to their complexity and non-deterministic behavior. On the
other hand, self-optimization can be used to increase the dependability of the
system during its operation. However, it has to be ensured, that the self-optimization
works dependable itself. To cope with these challenges, the multi-level dependability
concept was developed. It enables predictive condition monitoring, influences
the objectives of the system and determines suitable means to improve the system''s
dependability during its operation. In this contribution we introduce a procedure
for the conceptual design of an advanced condition monitoring based on the system''s
principle solution. The principle solution describes the principal operation mode
of the system and its desired behavior. It is modeled using the specification
technique for the domain-spanning description of the principle solution of a self-optimizing
system and consists of a coherent system of eight partial models (e.g. requirements,
active structure, system of objectives, behavior, etc.). The partial models are
analyzed separately in order to derive the components of the multi-level dependability
concept. In particular, the reliability analysis of the partial model active structure
is performed to identify the system elements to be monitored and parameters to
be measured. The principle solution is extended accordingly: e.g. with system
elements required for the realization of the dependability concept. The advantages
of the method are shown on the self-optimizing guidance module of a railroad vehicle.'

text: Piezoelectric inertia motors, also known as ``stick-slip-drives'', use the
inertia of a body to drive it by means of a friction contact in small steps. While
these steps normally involve stiction and sliding, the motors can also operate
in ``slip-slip'' mode without any phase of static friction. In this contribution,
a one degree of freedom model of an inertia motor driven by an ideal actuator
is analysed. Start-up and constant velocity operation of the motor are investigated
and appropriate quantities to compare ``stick-slip'' and ``slip-slip'' operation
are determined. Different aspects such as velocity, uniformity of motion, load
capacity, robustness, efficiency, and wear are considered. The analysis allows
both modes to be applied advantageously in different applications and can widen
the field of application of piezoelectric inertia motors. Motor designers are
enabled to choose the appropriate mode of operation and the best drive parameters
for their individual applications.

mit einer Online-Bewertung des aktuellen Systemzustands kombiniert. Dieses erlaubt
Maßnahmen zur Zuverlässigkeitssteigerung abzuleiten. Das Konzept wird auf ein
X-by-wire-Fahrzeug mit Einzelradaktorik angewandt. Dabei steht zunächst die Beeinflussung
der Ziele der Mehrzieloptimierung zugunsten der Zuverlässigkeit des Systems im
Vordergrund. In Simulationen wird gezeigt, dass über die Wahl und Gewichtung der
Zielfunktionen die Quer- und Längskräfte an den Rädern vorteilhaft verteilt werden
können. \r\n\r\nIn this contribution a concept is illustrated, which combines
the multi-objective optimization technique with an online assessment of the current
system state. This allows deriving measures to increase the reliability of the
system. The concept is applied to an X-by-wire vehicle with single-wheel actuators.
The emphasis is here mostly on the influence of the objectives of the multiobjective
optimization for the benefit of the reliability of the system. It is demonstrated
in simulations, that the lateral and longitudinal forces at the wheels can be
distributed advantageously by the selection of the suitable objective functions
and the appropriate weights."

text: 'A profound description of friction in wheel--rail contact plays an essential
role for optimization of traction control strategies, as input quantity for railway
simulations in general and for the estimation of wear and rolling contact fatigue.
A multitude of wheel--rail contact models exists, however, traction--creepage
curves obtained from measurements show quantitative and qualitative deviations.
There are several phenomena which influence the traction--creepage characteristics:
Mechanisms resulting from surface roughness, frictional heating or the presence
of interfacial fluids can have a dominating influence on friction. In this paper,
a new wheel--rail contact model, accounting for these influential parameters,
will be presented. The presented model accounts for the interaction of an interfacial
fluid model for combined boundary and mixed lubrication of rough surfaces with
a wheel--rail contact model that additionally accounts for frictional heating.
A quantitative comparison with measurements found in the literature is not conducted,
since the exact conditions of the measurements are mostly unknown and parameters
can easily be adjusted to fit the measurements. Emphasis is placed on the qualitative
behavior of the model with respect to the measurements and good agreement is found.
The dependence of the maximum traction coefficient on rolling velocity, surface
roughness and normal load is studied under dry and water lubricated conditions.'

text: Es wird eine Anordnung zur mehrdimensionalen Messung von Schwingungen eines
Objektes vorgeschlagen, umfassend ein Vibrometer und eine erste Ablenkeinheit,
mittels welcher der Messstrahl des Vibrometers in wenigstens zwei erste Raumrichtungen
ablenkbar ist, sowie wenigstens eine zweite Ablenkeinheit, mittels welcher der
aus einer der wenigstens zwei ersten Raumrichtungen auf eine zweite Ablenkeinheit
eintreffende Messstrahl derart ablenkbar ist, dass ein Messpunkt des Objekts aus
einer ersten Raumrichtung und wenigstens einer zweiten Raumrichtung oder wenigstens
zwei zweiten Raumrichtungen damit erfassbar ist. Bei dem zum Betrieb der Anordnung
vorgesehenen Verfahren wird der Messstrahl eines Vibrometers in wenigstens zwei
erste Raumrichtungen abgelenkt, woraufhin wenigstens ein Messstrahl einer ersten
Raumrichtung ein zweites Mal derart abgelenkt wird, dass ein Messpunkt des Objekts
aus einer ersten Raumrichtung und wenigstens einer zweiten Raumrichtung oder wenigstens
zwei zweiten Raumrichtungen erfasst wird, insbesondere so dass die zu untersuchenden
Bewegungskomponenten in den Messsignalen, welche entlang der ersten und zweiten
Raumrichtungen gewonnen werden, enthalten sind. The arrangement has a first deflecting
unit (3) for deflecting a measuring beam of a vibrometer (2) in spatial directions
(4-6, 4-6). Second and third deflecting units (7, 8) deflect the beam arriving
from one of the spatial directions such that a measuring point (9) of an object
(1) is detectable with the beam from the spatial direction or the spatial directions.
The first deflecting unit is designed as a scanning unit, where the measuring
point is detected by the scanning unit. A measuring instrument measures focus
quality and is connected to actuators for adjustment of the focus quality. An
independent claim is also included for a method for multidimensional measurement
of oscillations of an object.

text: Bei der Konstruktion von Maschinen ist es oftmals erforderlich, Schwingungen
minimal zu halten. Um z.B. die Lebensdauer zu erhöhen, Material einzusparen oder
den Geräuschpegel gering zu halten muss oft ein großer Aufwand zur Dämpfung von
auftretenden Schwingungen betrieben werden. In vielen technischen Anwendungen
werden Einzelteile miteinander verschraubt. Diese Fügestellen können gezielt und
mit wenig Aufwand zur Schwingungsdämpfung herangezogen werden. Die Berechnung
des dynamischen Verhaltens verschraubter Strukturen stellt immer noch eine Herausforderung
dar. Es wurde eine Methode entwickelt, um den eingeschwungenen Zustand elastischer,
miteinander verschraubter Körper mit rauen Fügestellen bei periodischer Anregung
zu berechnen. Als Basis dienen Finite Elemente Modelle der einzelnen Teile, deren
Freiheitsgrade durch modale Kondensation reduziert werden. Unter Anwendung des
Verfahrens von Ritz und Galerkin wird eine Näherungslösung für den eingeschwungenen
Zustand des nichtlinearen, gekoppelten Systems ermittelt. Abhängig von den Schraubenvorspannkräften
sowie den bestimmenden Parametern der Kontaktflächen, Rautiefe und Reibungskoeffizient,
kann die Systemantwort berechnet und optimiert werden. Um die Berechnungsmethode
zu verifizieren wurden Experimente durchgeführt. Der Vergleich zwischen Messung
und Rechnung zeigt eine gute Übereinstimmung. ({\copyright} 2010 Wiley-VCH Verlag

text: For many technical applications it is necessary to avoid or to reduce vibrations.
Factors benefiting from vibration reduction are for example the durability of
the application, which is increased, as well as cost expenses and the level of
noise, which are both decreased. Rough, bolted interfaces are common in most machines
and can be used as damping devices with some effort. Perhaps in future such contact
surfaces could be used as damping devices at the interfaces of an automotive engine
or exhaust system. Nevertheless it is difficult to predict the effect of a change
in contact interface parameters on the dynamic behavior of the entire mechanical
system. Therefore a method for calculating the steady state behavior of elastic
multi-body systems was developed. The basis of this method is a finite element
model of each contacting unit. On each model a modal reduction is applied in order
to reduce the degrees of freedom. The method of Ritz and Galerkin is used to calculate
the frequency response functions of the reduced system including contact. This
method allows the calculation of the steady-state behavior of elastic multi-body
systems with rough, bolted contact interfaces, by taking the pre-stress of the
bolts, the roughness and the friction coefficient of the contacting surfaces as
parameters. In order to verify calculated results, a test stand was built. The
comparison of calculated and experimental results showed a satisfying correlation.

text: 'Piezoelektrische Trägheitsmotoren nutzen die Trägheit einer bewegten Masse,
um diese in kleinen Schritten durch abwechselnde Haft- und Gleitphasen voranzutreiben.
Eine Kernfrage bei der Entwicklung eines piezoelektrischen Trägheitsmotors ist,
welches elektrische Ansteuersignal für das gewünschte Motorverhalten optimal ist.
Das elektrische Signal führt zu einer Bewegung des piezoelektrischen Aktors und
damit der Antriebsstange, die den reibschlüssigen Vortrieb bewirkt. Entsprechend
wird diese Fragestellung in zwei Teilen untersucht: Anhand eines Starrkörpermodells
werden zunächst Bewegungsverläufe für die Antriebsstange ermittelt, mit denen
die maximale Geschwindigkeit erreicht wird. Dabei werden drei Antriebsmodi identifiziert.
Mit allen kann eine höhere Geschwindigkeit als mit der heute häufig verwendeten
Sägezahnanregung erreicht werden. Anschließend wird ein einfaches dynamisches
Modell eines piezoelektrischen Aktors genutzt, um die notwendigen elektrischen
Ansteuersignale für die verschiedenen Antriebsmodi zu bestimmen. Es zeigt sich,
dass das gewählte einfache Modell hierzu nur bedingt geeignet ist.'

text: A model based design approach for improved piezoelectric inertia motors is
presented. Three velocityoptimized movement patterns for the driving body have
been derived. The influence of the motor parameters and the process of designing
an application specific motor with maximum velocity are shown. A simple dynamic
model of the piezoelectric actuator is used to calculate the voltage signal for
achieving the desired movement pattern. Observed distortions of the optimum pattern,
their influence on the motion of the driven body and different methods to reduce
them are discussed.

text: Self-optimizing systems are able to adapt their behavior autonomously according
to their current self-determined objectives. Unforeseen influences could lead
to dependability-critical behavior of the system. Methods are required which secure
self-optimizing systems during operation. These methods to increase the dependability
of the system should already be taken into consideration in the design process.
This paper presents a guideline for the dependability-oriented design of self-optimizing
systems, which integrates established classical methods like failure mode and
effects analysis as well as methods based on self-optimization. On the one hand
self-optimization is used to increase the dependability of the system by integrating
objectives like safety, availability, and reliability to the objectives of the
system. On the other hand methods are required to ensure the self-optimization
itself. As basis for this guideline serves the principle solution of the system.
The six phases of the guideline extend the design process and lead to an enhanced
principle solution. Additionally, the guideline illustrates phases to implement
and validate the self-optimizing system. The proposed guideline is applied to
an innovative rail-bound vehicle, called RailCab, which is equipped with self-optimizing
function modules.
