Flow forming is recognized for its precision in producing rotationally symmetric components, but the use of metastable austenitic stainless steel (AISI 304L) introduces challenges due to uncontrolled strain-induced α’ martensite formation. Variations in factors such as eccentricity and batch inconsistencies lead to unpredictable microstructural profiles, limiting reproducibility [1,2]. This study addresses these issues by incorporating thermal actuators for cryogenic cooling and induction heating to regulate forming temperatures, enabling control of the α’-martensite content. Experimental investigations demonstrate that local tempering during thermomechanical reverse flow forming produces discernible variations in microstructure, affecting mechanical and magnetic properties [3]. Controlled local adjustments of α’-martensite content allow for customization of properties in seamless tubes, advancing manufacturing capabilities for complex, defect-free components. The results presented demonstrate promising strategies for implementation within the context of closed-loop property control in flow forming.</jats:p>"}],"keyword":["Flow Forming","Thermomechanical Forming","α’-Martensite","Property Control"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2025","publisher":"Materials Research Forum LLC","date_created":"2025-05-15T06:59:28Z","title":"Advanced thermomechanical flow forming: A novel approach to α’-martensite control for enhanced material properties"},{"publication":"2025 Energy Conversion Congress &amp;amp; Expo Europe (ECCE Europe)","type":"conference","status":"public","abstract":[{"lang":"eng","text":"Three-phase cascaded H-bridge converters (CHBs) in star configuration require reliable current controllers to evenly charge the module DC-link capacitors. Conventionally, a current control in dq-coordinates is utilized. At steady state, the resulting calculated reference arm voltages are sinusoidal, have identical amplitudes and show a phase shift of 120 degree to each other. For balanced grid inductors, the resulting grid currents also have the same amplitude. However, own simulations show that unbalanced grid inductors always lead to different grid current amplitudes (4% difference in this case). As a result, the averaged charging module powers differ and the peak DC-link capacitor voltage rises as well. In the first step, an adaptation of an existing zero-sequence voltage injection is proposed. For balanced grid inductors, it converges to the 3rd harmonic voltage injection which can reduce the peak-to-peak DC-link voltage ripple up by to 50% and balances the power between the phases. However, unbalanced grid inductors still lead to the same unbalanced grid currents of 4%. Therefore, a new method with 4 integrators based on linear regression is proposed to achieve sinusoidal grid currents for unbalanced inductors. The proposed method has a similar transient dynamic as the conventional dq control, but balances the grid currents nearly ideally. Simulation results of a 1MW cascaded H bridge and a scaled-down prototype verify the proposed method."}],"department":[{"_id":"52"}],"user_id":"34289","_id":"63157","language":[{"iso":"eng"}],"keyword":["Cascaded H-Bridge","Current Control","dq Transformation","Linear Regression","Unbalanced Inductors"],"publication_status":"published","citation":{"ama":"Unruh R, Böcker J, Schafmeister F.

Specifically, the dynamics is described by a second order ODE containing an affine control term. Classically, Pontryagin's maximum principle gives necessary optimality conditions for the optimal control problem. For smooth problems, alternatively, a variational approach based on an augmented objective can be followed. Here, we propose a new Lagrangian approach leading to equivalent necessary optimality conditions in the form of Euler-Lagrange equations. Thus, the differential geometric structure (similar to classical Lagrangian dynamics) can be exploited in the framework of optimal control problems. In particular, the formulation enables the symplectic discretisation of the optimal control problem via variational integrators in a straightforward way.","lang":"eng"}],"publication":"Journal of Computational Dynamics"},{"type":"journal_article","publication":"Journal of Manufacturing Systems","status":"public","user_id":"51811","department":[{"_id":"277"}],"_id":"53212","language":[{"iso":"eng"}],"keyword":["Industrial and Manufacturing Engineering","Hardware and Architecture","Software","Control and Systems Engineering"],"publication_status":"published","publication_identifier":{"issn":["0278-6125"]},"citation":{"apa":"Mahmoodi, E., Fathi, M., Tavana, M., Ghobakhloo, M., &#38; Ng, A.

The total output power of all LLC converters must be constant to supply a load such as a wa-\r\nter electrolyzer. However, each individual LLC converter can vary its output power as long as the total output\r\npower remains constant. This opens new possibilities in increasing the system efficiency and robustness. Usually,\r\nthe DC-link voltage of each module capacitor shows a 2nd harmonic voltage ripple. However, the total stored energy\r\nin all DC-link capacitors is constant within a grid period for a balanced three-phase system. By controlling each\r\nLLC converter’s output power locally to be proportional to the energy stored in its DC-link capacitor, modules with\r\na lower instantaneous DC-link voltage transfer less power to the load than modules with a higher DC-link voltage.\r\nAs a result, a higher efficiency, voltage gain and lower peak resonant capacitor voltage can be achieved with the\r\nsame components.

Many companies have already gained experience in the introduction of Systems Engineering. Therefore, as part of the SE4OWL research project, the need to conduct a study including expert interviews and to collect the experiences of experts was identified. A total of 78 hypotheses were identified from 13 expert interviews concerning the lessons learned. Using exclusion criteria, 52 hypotheses were validated in a subsequent quantitative survey with 112 participants. Of these 52 hypotheses, 40 could be confirmed based on the survey results. Only four hypotheses were rejected, and eight could neither be confirmed nor rejected. Through this research, guidance is provided to companies to leverage best practices for the introduction of their own Systems Engineering and to avoid the poor practices of other companies.</jats:p>","lang":"eng"}]},{"publication_identifier":{"issn":["2644-1284"]},"publication_status":"published","year":"2023","page":"1-14","citation":{"ama":"Winkel F, Wallscheid O, Scholz P, Böcker J.

The two MBRTs induced either an object-based spatial transformation (based on a same-different judgment) or an egocentric transformation (based on a left-right judgment). In Experiment 1, 48 participants were tested while standing on an even ground (low balancing requirements) or on a balance board (high balancing requirements). In Experiment 2, 32 participants performed while either standing still on a vibration plate or with the vibration plate moving in a low (20 Hz) or high (180 Hz) frequency. In both experiments, the results for response time and response error revealed effects of rotation angle and type of task. An effect of balancing condition was only observed for response error in Experiment 1. More precisely, response times and response errors increased for higher rotation angles. Also, performance was better for egocentric than for object-based spatial transformations. However, the different challenges to dynamic stability in Experiments 1 and 2 did not influence performance in the two MBRTs (except for response errors in Experiment 1) nor in a control condition (Experiment 1) without mental rotation."}],"status":"public","_id":"48682","user_id":"23188","department":[{"_id":"17"},{"_id":"266"}],"article_number":"103156","article_type":"original","keyword":["Mental rotation","Balance control","Perturbation","Embodiment"],"language":[{"iso":"eng"}]},{"quality_controlled":"1","publication_status":"published","year":"2023","page":"253-524","citation":{"ama":"Gräßler I, Hieb M.

One example relevant to the automobile industry is the United Nations Economic Commission of Europe (UN ECE), which specifies the homologation of automobile series and requires proof of traceability. The required traceability can be achieved by modeling system artifacts and their relations in a consistent, seamless model—an effect-chain model. Currently, no in-depth methodology exists to support engineers in developing certification-compliant effect-chain models. For this purpose, a new methodology for certification-compliant effect-chain modeling was developed, which includes extensions of an existing method, suitable models, and tools to support engineers in the modeling process. For evaluation purposes, applicability is proven based on the experience of more than 300 workshops at an automotive OEM and an automotive supplier. The following case example is chosen to demonstrate applicability: the development of a window lifter that has to meet the demands of UN ECE Regulations R156 and R21. Results indicate multiple benefits in supporting engineers with the certification-compliant modeling of effect chains. Three benefits are goal-oriented modeling to reduce the necessary modeling capacity, increasing model quality by applying information quality criteria, and the potential to reduce costs through automatable effect-chain analyses for technical changes. Further, companies in the automotive and other industries will benefit from increased modeling capabilities that can be used for architecture modeling and to comply with other regulations such as ASPICE or ISO 26262.</jats:p>","lang":"eng"}],"publication":"Systems","keyword":["Information Systems and Management","Computer Networks and Communications","Modeling and Simulation","Control and Systems Engineering","Software"],"language":[{"iso":"eng"}],"year":"2023","quality_controlled":"1","issue":"3","title":"Methodology for Certification-Compliant Effect-Chain Modeling","publisher":"MDPI AG","date_created":"2023-05-03T08:37:36Z","status":"public","type":"journal_article","article_number":"154","_id":"44382","user_id":"5905","department":[{"_id":"152"}],"citation":{"bibtex":"@article{Gräßler_Wiechel_Koch_Sturm_Markfelder_2023, title={Methodology for Certification-Compliant Effect-Chain Modeling}, volume={11}, DOI={<a href=\"https://doi.org/10.3390/systems11030154\">10.3390/systems11030154</a>}, number={3154}, journal={Systems}, publisher={MDPI AG}, author={Gräßler, Iris and Wiechel, Dominik and Koch, Anna-Sophie and Sturm, Tim and Markfelder, Thomas}, year={2023} }","short":"I.

Für kleine Losgrößen bietet sich hier insbesondere das Fertigungsverfahren des Drückwalzens an. Der konventionelle, industriell genutzte Drückwalzprozess stößt allerdings aufgrund der Prozesskomplexität hinsichtlich der Reproduzierbarkeit an seine Grenzen. Dies wird in der Praxis teilweise durch personengebundenes Erfahrungswissen kompensiert. Auch ist es nicht möglich, Bauteileigenschaften definiert einzustellen. Aus diesem Grund bietet der Einsatz einer neuartigen Eigenschaftsregelung Chancen zur Weiterentwicklung des Fertigungsprozesses und die Möglichkeit zur Prozessautomatisierung. Hier werden die Werkzeugbahnen abhängig einer Online-Eigenschaftsmessung über eine zusätzliche Reglerkaskade manipuliert. Die Entwicklung einer solchen Eigenschaftsregelung erfordert den Einsatz geeigneter, modellbasierter Entwurfsmethoden. In diesem Beitrag wird daher ein regelungstechnisches Systemmodell für das Drückwalzen metastabiler austenitischer Edelstähle vorgestellt. Das Simulationsmodell weist aufgrund seiner Echtzeitfähigkeit neben dem Einsatz als reines Entwurfsmodell weitere Nutzungsmöglichkeiten z.B. in Beobachtern auf und grenzt sich somit von domänenspezifischen Simulationstools wie der FEM ab.</jats:p>"}]}]
