  text: "Dieser Beitrag stellt ein Konzept vor, welches die Methode der Mehrzieloptimierung
    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.

  text: New mechatronic systems, called self-optimizing systems, are able to adapt
    their behavior according to environmental, user and system specific influences.
    Self-optimizing systems are complex and due to their non-deterministic behavior
    comprise hidden risks, which cannot be foreseen in the design phase of the system.
    Therefore, modifications of the ISO 17359 condition monitoring policy for being
    able to cope with this new kind of systems are presented. Besides avoiding critical
    situations evoked by self-optimization, the proposed concept uses self-optimization
    to increase the dependability of the system. This concept is applied to the active
    guidance module of an innovative rail-bound vehicle. First test drives provide
    information for the enhancement of the implementation of realtime switching to
    appropriate control strategies. The different control strategies are investigated
    in detail. It is illustrated that influences on the system like different track
    sections or the desired velocity of the RailCab effect the system and can lead
    to a higher amount of flange contacts, which indicate higher wear and thus a reduction
    of the availability of the system. Therefore, these influences should be minded
    within the condition monitoring policy. Consequently, this article presents the
    condition monitoring policy for self-optimizing function modules and its application
    to the active railway guidance module.

  text: Die erweiterten Möglichkeiten der Informationsverarbeitung mechatronischer
    Systeme erlauben es, mechatronische Systeme selbstoptimierend zu gestalten. Dabei
    bezieht sich die Selbstoptimierung auf die Fähigkeit des Systems, sich an die
    aktuelle Umfeldsituation anzupassen; wobei das System im Allgemeinen mehrere relevante
    Ziele verfolgt. Wurde eine Umfeldveränderung bemerkt, so müssen diese Ziele an
    die neue Situation angepasst und das resultierende Verhalten ausgewählt werden.
    In diesem Beitrag wird das selbstoptimierende Spurführungsmodul näher untersucht.
    Das Spurführungsmodul ist Bestandteil eines innovativen schienengebundenen Verkehrssystems,
    genannt RailCab, und dient zur Lenkung des einzelnen Fahrzeugs. Ziele des Spurführungsmoduls
    bestehen darin, die Verlässlichkeit des Spurführungsmoduls zu erhöhen sowie möglichst
    wenig Energie zu verbrauchen. Um kritische Systemzustände zu erkennen bzw. frühzeitig
    zu verhindern wird eine Vorgehensweise zur Einrichtung einer Zustandsüberwachung
    für selbstoptimierende Systeme beschrieben. Diese wird auf dem realen Versuchsträger
    im Maßstab 1:2,5 implementiert. Die Auswertung von Versuchsfahrten zeigt, dass
    gerade beim Auftreten eines Fehlers das Umschalten vom Ziel ''Energieverbrauch
    minimieren`` auf das Ziel ''Verlässlichkeit maximieren`` sinnvoll ist.

  text: Recent advances in information processing enable new kinds of technical systems,
    called self-optimizing systems. These systems are able to adapt their objectives
    and their behavior according to the current situation and influences autonomously.
    This behavior adaptation is non-deterministic and hence self-optimization is a
    risk to the system, e.g. if the result of the self-optimization process does not
    match the suddenly changed situation. In contrary, self-optimization could be
    used to increase the dependability by pursuing objectives like reliability and
    availability. In our preceding publications we introduced the so called multi-level
    dependability concept to cope with this new kind of systems (cf. [6]). This concept
    comprises the monitoring of the system behavior, the classification of the current
    situation, and the selection of the appropriate measure, if reliability limits
    are exceeded. In this paper we present for the first time experimental results.
    The dependability concept is implemented in the self-optimizing active guidance
    system of a railway vehicle. The test drives illustrate clearly that the proposed
    concept is able to cope with, e.g., sensor failures, and is able to increase the
    reliability and availability of the active guidance module.

  text: New mechatronic systems, called self-optimizing systems, are able to adapt
    their behavior according to environmental, user and system specific influences.
    Self-optimizing systems are complex and due to their non-deterministic behavior
    comprise hidden risks, which cannot be foreseen in the design phase of the system.
    Therefore, this paper presents modifications of the current condition monitoring
    policy, to be able to cope with this new kind of systems. Beside avoiding critical
    situations evoked by self-optimization, the proposed concept uses self-optimization
    to increase the dependability of the system. In this case, the concept is applied
    to the active guidance module of an innovative rail-bound vehicle.

  text: Numerical predictions of the forced vibration of a disk assembly including
    frictional effects between the shrouds are presented concerning engineering needs
    for the blade design process. Assuming a tuned disk 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 nonlinear 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{\^a}30deg) between the circumferential
    direction and the normal vector to the contact surface.
