Test scenarios can be generated by combining test cases, or by integrating test cases into pre-specified scenarios. Based on a systematic literature analysis a method is developed to simplify verification planning by creating new test scenarios and enriching existing ones. To assist the V&V engineer in planning test scenarios, a catalogue of combination premises is created to support the method. The method is evaluated in the development of a platform for emergency management. Evaluation proves that the method makes modelling of test scenarios more efficient.","lang":"eng"}],"publication":"Procedia CIRP","volume":136,"user_id":"81788","_id":"61103","publisher":"Elsevier BV","page":"213-218","conference":{"end_date":"2025-04-04","name":"35th CIRP Design Conference","start_date":"2025-04-02","location":"Patras, Greece"},"status":"public","oa":"1","project":[{"name":"CREXDATA: Kritische Maßnahmenplanung über extreme Datenmengen","_id":"516"}],"quality_controlled":"1","citation":{"mla":"Gräßler, Iris, et al. “Method for Systematic Creation of Test Scenarios for Early Customer Involvement.” <i>Procedia CIRP</i>, vol. 136, Elsevier BV, 2025, pp. 213–18, doi:<a href=\"https://doi.org/10.1016/j.procir.2025.08.038\">https://doi.org/10.1016/j.procir.2025.08.038</a>.","ama":"Gräßler I, Ebel M, Pottebaum J.

Es fehlt jedoch an Grundlagenwissen und Verständnis, wie die datengetriebenen Methoden der Informatik mit bewährten modellbasierten Ingenieursmethoden wie dem modellbasierten Entwurf in der Mechatronik und Methoden der Regelungstechnik sinnvoll kombiniert werden können, um hybride Modelle zu erhalten. Diese ingenieurwissenschaftlichen Methoden basieren auf physikalischen Verhaltensmodellen, die eine besonders verdichtete und interpretierbare Darstellung von Wissen darstellen und insbesondere kausale Zusammenhänge beschreiben. Für spezifische regelungstechnische Anwendungen gibt es umfangreiches Vorwissen in Form von bekannten Strukturen und Informationen, wie z.B. (Teil-)Modelle oder Parametersätze, die auch bei der Anwendung von Methoden wie dem maschinellen Lernen genutzt werden sollten. Eine solche sinnvolle systematische Verknüpfung ist wissenschaftlich, insbesondere im Hinblick auf die industrielle Anwendung, noch nicht ausreichend untersucht worden und sehr vielversprechend. In diesem Beitrag werden die Ergebnisse der Nachwuchsforschungsgruppe DART – Datengetriebene Methoden in der Regelungstechnik vorgestellt. Das Hauptziel war es, die synergetische Kombination von modell- und datengetriebenen Methoden für regelungstechnische Aufgaben zu erforschen und es werden alle wichtigen Forschungsergebnisse aber auch die verwendeten Grundprinzipien des maschinellen Lernens in diesem Beitrag dargestellt."},{"lang":"eng","text":"In the course of digitalization, machine learning and data-driven methods are currently receiving a great deal of attention in science and industry. However, there is a lack of basic knowledge and understanding of how data-driven methods in computer science can be meaningfully combined with proven model-based engineering methods such as model-based design in mechatronics and control engineering methods to obtain hybrid models. These engineering methods are based on physical models, which represent a particularly condensed and interpretable representation of knowledge and, in particular, describe causal relationships. For specific control engineering applications, there is extensive prior knowledge in the form of known structures and information, such as (partial) models or parameter sets, which should also be used when applying methods such as machine learning. Such a meaningful systematic connection has not yet been sufficiently investigated scientifically, especially with regard to industrial applications, and is very promising.

Besides high power ultrasound applications like ultrasonic cleaning and ultrasonic welding, which are often not strongly restricted regarding their weight, costs, and construction space, there are many applications in the low to medium power range like handheld surgical instruments, medical inhalers, or ultrasonic cutters. For the latter there is often a strong demand for low weight and construction space and low costs to be competitive in mass production. Another challenge that arises from the RoHS-directive [1] is, that new ultrasonic devices should avoid the use of lead-containing PZT-materials. Against this background there is a demand for lead-free, small and lightweight and cost-effective ultrasonic transducers.\r\nIn many of the above-mentioned applications, pre-stressed Bolted-Langevine-Transducers (BLT) based on lead-containing PZT-materials are established to generate ultrasonic vibrations. These are quite advantageous in many ways and can be built tailored to each application and even for high power of thousands of watts. But due to the required steps during their manufacturing process (machining parts, assembly, pre-stressing, frequency tuning, …), these transducers remain expensive. Furthermore, due to the operation in resonance, the construction space of these transducers is linked to their wavelength and cannot be reduced remarkably.\r\nFor these reasons, our aim is to present an innovative lead-free ultrasonic transducer for low to medium power applications, that is based on bending vibrations instead of longitudinal vibrations. This design enables to build very small transducers. Furthermore, due to their simple construction, these transducers can be built at low manufacturing costs and are well suited for industrial mass production. The use of lead-free piezoelectric materials makes this transducer design ready for future applications.\r\nIn our contribution we will present the model-based design of a lead-free 30 kHz bending transducer for applications up to 10 W. Furthermore, the comprehensive experimental analysis of this transducer-prototype in applications like mist generation or ultrasonic drilling will be presented. The results will be compared to a PZT-based bending transducer and a classical BLT to show the potential and limits of these kind of transducers and lead-free materials.\r\n"}],"file_date_updated":"2026-04-02T12:46:09Z","citation":{"bibtex":"@inproceedings{Bornmann_Littmann_Scheidemann_Hemsel_2025, title={Innovative lead-free ultrasonic bending transducers for low to medium power applications}, author={Bornmann, Peter and Littmann, Walter and Scheidemann, Claus and Hemsel, Tobias}, year={2025} }","ama":"Bornmann P, Littmann W, Scheidemann C, Hemsel T.

Examples are ultrasonic welding of plastics or metal, surgery processes like cutting of tissue or bone, and the excitation of cavitation in liquids for ultrasonic cleaning. From a physical point of view, many of these processes are characterised by non-constant damping conditions for the ultrasonic actuators, since the systems need to be driven in unloaded as well as in high-loaded states. To get high power output, the piezoelectric actuators are usually driven in or near resonance at precisely defined vibration amplitudes. This is a quite complicated task  especially if cost or mass optimized PZT transducers are used or if lead-free piezoelectric ceramics are applied to replace lead-containing materials. In particular the sudden change between loading states is very challenging for electronic excitation and control. The present contribution gives insight into typical problems that may arise in context with sudden load-changes during operation, e.g. uncontrolled jumps in voltage and velocity amplitudes. Measurements on ultrasonic power actuators being abruptly immersed into water at high amplitude are discussed for illustration. Observations during spontaneous load-changes are explained, and it is shown that several problems may be defused by driving the actuators in antiresonance or using a particular driving point in-between resonance and antiresonance (“falling edge control”). The different control strategies are investigated always using just one single hardware.","lang":"eng"}],"file":[{"date_created":"2026-04-02T12:41:08Z","creator":"hemsel","file_id":"65353","content_type":"application/pdf","success":1,"relation":"main_file","date_updated":"2026-04-02T12:41:08Z","file_name":"ICU_2025_Littmann.pdf","access_level":"closed","file_size":2522135}],"date_created":"2026-03-02T11:19:46Z","type":"conference","department":[{"_id":"151"}]},{"_id":"65221","publisher":"LibreCat University","doi":"https://doi.org/10.48447/BR-2025-492","user_id":"85414","year":"2025","title":"BESCHREIBUNG DES R- UND DES TEMPERATUREINFLUSSES SOWIE DES EINLAUFVERHALTENS BEI EXPERIMENTELL BESTIMMTEN RISSFORTSCHRITTSKURVEN MIT DEM EXPONENTIALANSATZ","status":"public","author":[{"full_name":"Kullmer, Gunter","first_name":"Gunter","last_name":"Kullmer","id":"291"},{"full_name":"Weiß, Deborah","last_name":"Weiß","first_name":"Deborah","id":"45673"},{"id":"41322","full_name":"Duffe, Tobias","last_name":"Duffe","first_name":"Tobias"},{"id":"4668","first_name":"Britta","last_name":"Schramm","full_name":"Schramm, Britta"},{"id":"106876","first_name":"Richard","last_name":"Ostwald","orcid":"0000-0003-2147-8444","full_name":"Ostwald, Richard"}],"date_updated":"2026-04-07T04:35:27Z","date_created":"2026-03-30T11:00:23Z","type":"research_data","department":[{"_id":"9"},{"_id":"143"}],"citation":{"chicago":"Kullmer, Gunter, Deborah Weiß, Tobias Duffe, Britta Schramm, and Richard Ostwald. <i>BESCHREIBUNG DES R- UND DES TEMPERATUREINFLUSSES SOWIE DES EINLAUFVERHALTENS BEI EXPERIMENTELL BESTIMMTEN RISSFORTSCHRITTSKURVEN MIT DEM EXPONENTIALANSATZ</i>.
