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.","lang":"eng"}],"date_created":"2019-05-13T11:04:04Z","place":"Leonberg","type":"conference","department":[{"_id":"151"}]},{"citation":{"chicago":"Tomberger, Christoph, Peter Dietmaier, Walter Sextro, and Klaus Six. “Friction in Wheel--Rail Contact: A Model Comprising Interfacial Fluids, Surface Roughness and Temperature.” <i>Wear</i> 271 (2011): 2–12. <a href=\"https://doi.org/10.1016/j.wear.2010.10.025\">https://doi.org/10.1016/j.wear.2010.10.025</a>.","short":"C.

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."}],"date_created":"2019-05-13T11:08:32Z","department":[{"_id":"151"}],"type":"journal_article","keyword":["Wheel--rail contact","Rolling contact","Friction","Interfacial fluid","Lubrication","Surface roughness","Contact temperature"],"author":[{"last_name":"Tomberger","first_name":"Christoph","full_name":"Tomberger, Christoph"},{"full_name":"Dietmaier, Peter","first_name":"Peter","last_name":"Dietmaier"},{"full_name":"Sextro, Walter","last_name":"Sextro","first_name":"Walter","id":"21220"},{"first_name":"Klaus","last_name":"Six","full_name":"Six, Klaus"}],"publication_identifier":{"issn":["0043-1648"]},"year":"2011","title":"Friction in wheel--rail contact: A model comprising interfacial fluids, surface roughness and temperature","intvolume":"       271","date_updated":"2022-01-06T07:04:19Z","language":[{"iso":"eng"}],"doi":"10.1016/j.wear.2010.10.025"},{"citation":{"short":"W.

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 GmbH & Co.

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."}],"quality_controlled":"1","citation":{"short":"J.S.  Hölzl, W.

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.","lang":"eng"}],"publication":"7.

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.

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.

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]).

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.

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."}],"date_created":"2019-05-13T09:31:52Z","keyword":["condition monitoring","mechatronic systems","rail bound vehicle","rail guidance module","self-optimization","self-optimizing function modules","condition monitoring","mechatronics","railway rolling stock","self-adjusting systems"],"type":"conference","department":[{"_id":"151"}]},{"user_id":"55222","publisher":"VDI Verlag GmbH","_id":"9560","language":[{"iso":"eng"}],"series_title":"12","page":"29 - 49","date_updated":"2022-01-06T07:04:16Z","author":[{"full_name":"Tonchev, Anton","last_name":"Tonchev","first_name":"Anton"},{"full_name":"Hirschberg, Wolfgang","first_name":"Wolfgang","last_name":"Hirschberg"},{"id":"21220","last_name":"Sextro","first_name":"Walter","full_name":"Sextro, Walter"},{"full_name":"Major, Zoltan","first_name":"Zoltan","last_name":"Major"},{"full_name":"Neges, Josef","last_name":"Neges","first_name":"Josef"}],"title":"Modellierung der Hysterese- und Adhäsionseffekte zwischen Bremsbelag und Bremsscheibe","status":"public","year":"2007","department":[{"_id":"151"}],"type":"conference","date_created":"2019-04-29T10:03:13Z","place":"Bad Neuenahr","citation":{"short":"A.

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.","lang":"eng"}],"quality_controlled":"1","citation":{"apa":"Szwedowicz, J., Visser, R., Sextro, W., &#38; Masserey, P.
