Hier breitet sich die Schwingungsenergie in Form stehender und fortschreitender Wellen zum akustischen Verbraucher hin aus. Es folgt eine gleichwertige und schaltungstreue Darstellung durch elektrische oder mechanische Vierpole, die für den Entwicklungsingenieur leichter zu handhaben sind und in Netzwerken direkt mit Masons Ersatzschaltung des piezoelektrischen Wandlers gekoppelt werden können. Danach werden die wichtigsten, messtechnisch zugänglichen Parameter anhand eines in Resonanznähe zulässigen Ersatzmodells mit konzentrierten elektrischen bzw. mechanischen Komponenten definiert. Als Schwerpunkt wird anschließend deren analytische Berechnung und messtechnische Verifizierung an typischen Beispielen demonstriert.

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.

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.

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."}],"publication":"Entwurf mechatronischer Systeme"},{"status":"public","abstract":[{"lang":"eng","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."}],"type":"conference","publication":"Reliability and Maintainability Symposium (RAMS), 2010 Proceedings - Annual","language":[{"iso":"eng"}],"keyword":["availability","dependability concept","multilevel dependability concept","railway vehicle","reliability","self optimizing active guidance system","self optimizing railway guidance system","situation classification","system behavior monitoring","optimal control","railways","reliability theory","self-adjusting systems"],"user_id":"55222","department":[{"_id":"151"}],"_id":"9763","citation":{"short":"C.

Diese werden aus Konfigurationen von Systemelementen mit einer inh{\\\"a}renten Teilintelligenz bestehen. Das Verhalten des Gesamtsystems wird durch die Kommunikation und Kooperation der intelligenten Systemelemente geprägt sein. Selbstoptimierung ermöglicht handlungsfähige Systeme mit inhärenter \"Intelligenz\", die in der Lage sind, selbständig und flexibel auf veränderte Betriebsbedingungen zu reagieren. Die Vision des SFB 614 ist eine neue Schule des Entwurfs von intelligenten mechatronischen Systemen. Diese neue Schule beruht auf einem Instrumentarium bestehend aus Vorgehensmodellen, Entwurfsmethoden und -werkzeugen und Praktiken. Das Instrumentarium entsteht im Wechselspiel mit der Entwicklung von anspruchsvollen Demonstratoren, die als repräsentativ für künftige Erzeugnisse des Maschinenbaus und verwandter Branchen wie der Automobilindustrie und der Medizintechnik gelten können. Vor diesem Hintergrund zeichnet sich die Herausforderung ab, derartige Systeme zuverlässig zu gestalten. Wir haben statt Zuverlässigkeit den Begriff Verlässlichkeit gewählt, weil er die Aspekte Verfügbarkeit, Zuverlässigkeit, Sicherheit und Vertraulichkeit umfasst und somit unser Anliegen auf den Weg zu den Erzeugnissen von morgen treffend zum Ausdruck bringt. Das vorliegende Buch ist das Ergebnis der projektübergreifenden interdisziplinären Zusammenarbeit in dem Arbeitskreis \"Sicherheit und Stabilität\" des SFB 614. Es gibt eine gut aufbereitete Einführung in den umfassenden Themenkomplex Verlässlichkeit und zeigt anhand von anspruchsvollen Beispielen der fortgeschrittenen Mechatronik, wie komplexe, stark durch Informations- und Kommunikationstechnik geprägte technische Systeme verlässlich gestaltet werden können. Dabei wird deutlich, dass das Wirkparadigma der Selbstoptimierung nicht nur größere Anstrengungen erfordert, um Verlässlichkeit zu erreichen, sondern auch neue Möglichkeiten für mehr Verlässlichkeit eröffnet.","lang":"eng"}],"author":[{"full_name":"Dell'Aere, Alessandro","last_name":"Dell'Aere","first_name":"Alessandro"},{"last_name":"Hirsch","full_name":"Hirsch, Martin","first_name":"Martin"},{"last_name":"Klöpper","full_name":"Klöpper, Benjamin","first_name":"Benjamin"},{"full_name":"Koester, Markus","last_name":"Koester","first_name":"Markus"},{"first_name":"Alexander","last_name":"Krup","full_name":"Krup, Alexander"},{"first_name":"Martin","full_name":"Krüger, Martin","last_name":"Krüger"},{"first_name":"Thomas","full_name":"Müller, Thomas","last_name":"Müller"},{"first_name":"Simon","full_name":"Oberthür, Simon","last_name":"Oberthür"},{"first_name":"Sebastian","last_name":"Pook","full_name":"Pook, Sebastian"},{"first_name":"Claudia","last_name":"Priesterjahn","full_name":"Priesterjahn, Claudia"},{"full_name":"Romaus, Christoph","last_name":"Romaus","first_name":"Christoph"},{"first_name":"Alexander","full_name":"Schmidt, Alexander","last_name":"Schmidt"},{"first_name":"Christoph","full_name":"Sondermann-Wölke, Christoph","last_name":"Sondermann-Wölke"},{"first_name":"Matthias","full_name":"Tichy, Matthias","last_name":"Tichy"},{"last_name":"Vöcking","full_name":"Vöcking, Henner","first_name":"Henner"},{"first_name":"Detmar","last_name":"Zimmer","full_name":"Zimmer, Detmar"}],"date_created":"2019-04-29T13:14:00Z","volume":235,"date_updated":"2022-01-06T07:04:16Z","publisher":"Heinz Nixdorf Institut, Universität Paderborn","title":"Verlässlichkeit selbstoptimierender Systeme -- Potenziale nutzen und Risiken vermeiden","citation":{"short":"A.

After a short characterisation of the two techniques and the identification of the main parameters, results of an analytical theory of local heat up, cooling, and heat diffusion are presented. The theory is based on a spherical model for hyperthermia with a critical thermal dose and on a cylinder-symmetrical model for thermo-ablation with a critical temperature threshold for thermal toxicity and cell death through coagulative necrosis. Two representative hard ware concepts are discussed. The hyperthermia applicator consists of a MHz transducer, which rotates concentrically in a water filled capsule with acoustically transparent window, and radiates collimated or focussed ultrasound under 45$\\,^{\\circ}$ into a concentric target area of nearly spherical symmetry. The applicator for thermo-ablation is a MHz transducer which radiates high intensity focussed ultrasound (HIFU) into \"cigar shaped\" target areas at the focal zone. Typical therapy diagrams for both techniques are presented. They show therapeutic target volumes as functions of the therapy time with the peak temperature or the radiated acoustic power as parameters. These diagrams are discussed under consideration of power requirement, maximal sound intensity, and power efficiency at close to optimized frequency conditions.","lang":"eng"}],"type":"journal_article","publication":"Acta Acustica united with Acustica","language":[{"iso":"eng"}],"user_id":"55222","department":[{"_id":"151"}],"_id":"9569"},{"citation":{"bibtex":"@inproceedings{Müller_Schiedeck_Hemsel_2008, title={Verlässlichkeitorientierte Technologiebewertung innovativer Aktortechnologien am Beispiel von Formgedächtnislegierungen}, booktitle={2.

Until now, new working principles for actuators have not been systematically investigated in the means of dependability. Therefore we developed a proceeding for a dependability-oriented evaluation of technologies. This is shown in the case of shape memory alloy actuators. \r\nDE: Die Realisierung von Systemen mittels innovativer Aktortechnologien scheitert oftmals an der Skepsis gegenüber der Verlässlichkeit (Vertrauen in die zuverlässige und sichere Funktionalität der Technologie). Diese liegt darin begründet, dass neue Aktortechnologien bzw. die Integration von innovativen physikalischen Wirkprinzipen innerhalb neuer Aktorkonzepte bisher noch nicht systematisch im Kontext der Verlässlichkeit untersucht werden. Daher haben wir ein Vorgehen zur verlässlichkeitsorientierten Technologiebewertung entwickelt. Neben der detaillierten Darstellung des Vorgehensmodells wird es exemplarisch anhand von Formgedächtnislegierungen zur Entwicklung innovativer Antriebslösungen angewendet.","lang":"eng"}],"type":"conference","publication":"2.
