Relative movements take place at the chain joint between pin and bush, which lead to wear of the chain joint due to friction and so to chain elongation. The chain joint is generally lubricated with oils, through which elastohydrodynamic processes can occur in the gap between the pin and the bush of the chain joint. A simulation model is developed here to examine these elastohydrodynamic processes considering a mass conserving cavitation model, the Newtonian flow behaviour of the lubricant and the structuring of the bush surface, whereby the real form of the bush is considered.

In dieser Arbeit werden dreidimensionale Kennwerte benutzt, um die Oberflächenqualität von Laser-Sinter Bauteiloberflächen und die Einflüsse aus unterschiedlichen Bereichen der gesamten Prozesskette zu evaluieren. Beispielsweise wurden objektive Kennwerte, mit deren Hilfe Orangenhaut zu identifizieren ist, und Prozessparameter, die diese deutlich vermindern, gefunden. Mittels Durchführung von haptischen Versuchen wurde das subjektive Empfinden ermittelt und konnten zu objektiven Kennwerten korreliert werden. Eine mikroskopische Betrachtung des flachen Oberflächenwinkels mit verschieden farbigen Pulvern zeigt neue Erkenntnisse zum Anschmelzvorgang von Partikeln an die Schmelze. Zur nachträglichen Glättung von Oberflächen wurden mechanische, chemische und optische Nachbehandlungsmethoden verwendet und deren Potential aufgezeigt. Eine abschließende neuartige Simulation der dreidimensionalen Topografie bildet die Grundlage für ein Programm zur automatischen und funktionsgerechten Orientierung von Bauteilen, welche am Beispiel eines realen Bauteils erfolgreich validiert wurde. Zusammengenommen zeigen die Ergebnisse, dass die richtige Wahl von Bauorientierung und Prozessparametern entscheidend für die Bauteilqualität ist und selbst eine aufwendige Nachbearbeitung eine ungeschickte Wahl derer nur schwerlich ausgleichen kann.\r\n","lang":"ger"}]},{"status":"public","_id":"33649","publisher":"Wiley","volume":4,"user_id":"71051","citation":{"ama":"Kessler J, Calcavecchia F, Kühne T.

As a result, the use of aluminum alloys is continuously increasing. Due to poor weldability of aluminum in combination with other materials, mechanical joining technologies like clinching are increasingly used. In order to predict relevant characteristics of clinched joints and to ensure the reliability of the process, it is simulated numerically during product development processes. In this regard the predictive accuracy of the simulated process highly depends on the implemented friction model. In particular, the frictional behavior between the sheet metals affects the geometrical formation of the clinched joint significantly. This paper presents a testing method, which enables to determine the frictional coefficients between sheet metal materials for the simulation of clinching processes. For this purpose, the correlation of interface pressure and the relative velocity between aluminum sheets in clinching processes is investigated using numerical simulation. Furthermore, the developed testing method focuses on the specimen geometry as well as the reproduction of the occurring friction conditions between two sheet metal materials in clinching processes. Based on a methodical approach the test setup is explained and the functionality of the method is proven by experimental tests using sheet metal material EN AW6014.

Many process parameters affect the bond strength, such like the bond normal force, ultrasonic power, wire material and bonding frequency. Today, process design, development, and optimization is most likely based on the knowledge of process engineers and is mainly performed by experimental testing. In this contribution, a newly developed simulation tool is presented, to reduce time and costs and efficiently determine optimized process parameter. Based on a co-simulation of MATLAB and ANSYS, the different physical phenomena of the wire bonding process are considered using finite element simulation for the complex plastic deformation of the wire and reduced order models for the transient dynamics of the transducer, wire, substrate and bond formation. The model parameters such as the coefficients of friction between bond tool and wire and between wire and substrate were determined for aluminium and copper wire in experiments with a test rig specially developed for the requirements of heavy wire bonding. To reduce simulation time, for the finite element simulation a restart analysis and high performance computing is utilized. Detailed analysis of the bond formation showed, that the normal pressure distribution in the contact between wire and substrate has high impact on bond formation and distribution of welded areas in the contact area.","lang":"eng"}],"publication":"Microelectronics Reliability","type":"journal_article","keyword":["Ultrasonic heavy wire bonding","Co-simulation","ANSYS","MATLAB","Process optimization","Friction coefficient","Copper-copper","Aluminium-copper"],"department":[{"_id":"151"}],"date_created":"2021-03-10T09:37:02Z","date_updated":"2023-09-21T14:15:33Z","publication_status":"published","intvolume":"       119","year":"2021","title":"Co-simulation of MATLAB and ANSYS for ultrasonic wire bonding process optimization","publication_identifier":{"issn":["0026-2714"]},"author":[{"id":"28647","full_name":"Schemmel, Reinhard","first_name":"Reinhard","last_name":"Schemmel"},{"first_name":"Viktor","last_name":"Krieger","full_name":"Krieger, Viktor"},{"full_name":"Hemsel, Tobias","first_name":"Tobias","last_name":"Hemsel","id":"210"},{"full_name":"Sextro, Walter","last_name":"Sextro","first_name":"Walter","id":"21220"}],"doi":"https://doi.org/10.1016/j.microrel.2021.114077","language":[{"iso":"eng"}]},{"abstract":[{"lang":"eng","text":"As an effective and accurate method for modelling composite materials, mean-field homogenization is still not well studied in modelling non-linear and damage behaviours of UD composites. Investigated micro FE-simulations show that the matrix of UD composites exhibits different average plastic behaviour, named as average asymmetric matrix plasticity (AAMP), when the composite behaves different under shear, longitudinal and transverse loadings. In this study, a non-linear mean-field debonding model (NMFDM) combining a mean-field model and a fibre–matrix interface debonding model, is developed to simulate UD composites under consideration of AAMP, fibre–matrix interface damage and progressive failure. AAMP is considered by using so-called stress mode factor, which is expressed in terms of basic invariants of the matrix deviatoric stress tensor and is used as an indicator for detection of differences in the loading mode. The material behaviour of UD composites with imperfect interface is assumed identical as for perfect interface and stiffness reduced fibres. Progressive failure criteria are established with consideration of fibre breakage and matrix crack for different fibre orientations. As a representative example for the NMFDM, a C30/E201 UD composite is studied. To verify the model, experiments are conducted on polymers, carbon fibres and UD CFRPs. Finally, the model is applied to simulate a perforated CFRP laminate, which shows excellent prediction ability on deformation, debonding and progressive failure."}],"publication":"Composites Part B: Engineering","department":[{"_id":"9"},{"_id":"154"},{"_id":"321"},{"_id":"149"}],"type":"journal_article","keyword":["Non-linear mean-field homogenization Average asymmetric plasticity of matrix Fibre–matrix interface debonding Micro-mechanical FE-simulation Progressive failure"],"date_created":"2021-08-18T06:20:21Z","intvolume":"       224","date_updated":"2025-06-06T08:08:32Z","publication_status":"published","author":[{"last_name":"Cheng","first_name":"C.","full_name":"Cheng, C."},{"last_name":"Wang","first_name":"Z.","full_name":"Wang, Z."},{"full_name":"Jin, Z.","last_name":"Jin","first_name":"Z."},{"first_name":"X.","last_name":"Ju","full_name":"Ju, X."},{"first_name":"Swetlana","last_name":"Schweizer","full_name":"Schweizer, Swetlana","id":"8938"},{"id":"553","last_name":"Tröster","first_name":"Thomas","full_name":"Tröster, Thomas"},{"first_name":"Rolf","last_name":"Mahnken","full_name":"Mahnken, Rolf","id":"335"}],"publication_identifier":{"issn":["1359-8368"]},"year":"2021","title":"Non-linear mean-field modelling of UD composite laminates accounting for average asymmetric plasticity of the matrix, debonding and progressive failure","doi":"10.1016/j.compositesb.2021.109209","language":[{"iso":"eng"}],"article_number":"109209","quality_controlled":"1","citation":{"apa":"Cheng, C., Wang, Z., Jin, Z., Ju, X., Schweizer, S., Tröster, T., &#38; Mahnken, R.

This approach involves so-called Huygens' box as an efficient radiation model inside an electromagnetic (EM) simulation tool and then transforms the scanned NF measured data into the FF. For this, the basic idea of the Huygens'box principle and the NF-to-FF transformation are briefly presented. The NF is measured on the Huygens' box around a device under test using anNF scanner, recording the magnitude and phase of the site-related magnetic and electric components. A comparison between a fullwave simulation and the measurement results shows a good similarity in both the NF and the simulated and transformed FF.Thus, this method is applicable to predict the FF behaviour of any electronic system by measuring the NF. With this knowledge, the RF design can be improved due to allowing a significant reduction of EM compatibility failure at the end of the development flow. In addition, the very efficient FF radiation model can be used for detailed investigations in various environments and the impact of such an equivalent radiation source on other electronic systems can be assessed.","lang":"eng"}],"date_created":"2021-03-18T13:49:49Z","type":"book_chapter","keyword":["Huygens' box","NF-to-FF transformation","efficient FF radiation model","FF behaviour","EMI assessment","PCB","near-field measurements","efficient radiation model","far-field behaviour","RF design process","far-field prediction","Huygens'box principle","fullwave simulation","electronic system radiation","equivalent radiation source","electromagnetic simulation tool","near-field scan data","EM compatibility failure reduction"],"department":[{"_id":"485"}]},{"_id":"20678","publisher":"Elsevier","language":[{"iso":"eng"}],"doi":"https://doi.org/10.1016/j.jajp.2020.100038","user_id":"34782","publication_identifier":{"unknown":["https://doi.org/10.1016/j.jajp.2020.100038"]},"author":[{"last_name":"Bielak","first_name":"Christian Roman","full_name":"Bielak, Christian Roman","id":"34782"},{"full_name":"Böhnke, Max","last_name":"Böhnke","first_name":"Max","id":"45779"},{"first_name":"Robert","last_name":"Beck","full_name":"Beck, Robert","id":"38279"},{"last_name":"Bobbert","first_name":"Mathias","full_name":"Bobbert, Mathias","id":"7850"},{"first_name":"Gerson","last_name":"Meschut","orcid":"0000-0002-2763-1246","full_name":"Meschut, Gerson","id":"32056"}],"status":"public","title":"Numerical analysis of the robustness of clinching process considering the pre-forming of the parts ","year":"2020","date_updated":"2022-03-24T09:39:11Z","publication_status":"published","date_created":"2020-12-02T16:21:34Z","department":[{"_id":"157"}],"keyword":["Clinching","process simulation","FEM","pre-straining","sensitivity analysis"],"type":"journal_article","citation":{"ieee":"C.

A \r\nsteeper elevation angle would result in a more balanced seasonal PV yield, at the cost of PV yield reductions during \r\nsummer, but allowing reduced storage capacities. Additionally, the effect of a single-axis tracking system has been \r\ninvestigated, generating more electricity during the morning and evening hours, thus reducing daily storage \r\nrequirements. The necessary PV size and storage capacities required for the German energy supply (1,500 TWh after \r\nelectrification of all sectors) via 100% renewable energies and a 50% solar share have been calculated via the \r\nHOMER Pro software, considering the bridging of periods of \"dark lulls“ in winter, using costs of 2030 (Table 1). \r\nResults: The increase of module elevation angles above the typical 30° leads to a reduction of investment and supply \r\ncosts. The optimum is reached at a cost reduction of -1.5% for an elevation angle at the latitude of the installation \r\nsite. An explanation is that high elevation angles are favorable for clear winter days, but not at all for the critical days \r\nwith diffuse irradiance only, so the battery capacity must be increased. For the same reason, tracking systems do not \r\noffer any cost advantage (at least for the ones without an option for horizontal positioning during diffuse days).","lang":"eng"}],"date_created":"2020-09-14T12:42:30Z","file":[{"creator":"krauter","date_created":"2022-01-06T13:41:20Z","relation":"main_file","date_updated":"2022-01-06T13:41:20Z","file_name":"Krauter Rustemovic Khatibi - Elevated Angle - EUPVSEC 2020.pdf","access_level":"closed","file_size":428312,"file_id":"29178","content_type":"application/pdf","success":1}],"department":[{"_id":"53"}],"type":"conference","keyword":["Energy Storage","PV system integration","Large Grid-connected PV systems","Simulation","Energy Supply Options"],"author":[{"full_name":"Krauter, Stefan","last_name":"Krauter","first_name":"Stefan","orcid":"0000-0002-3594-260X","id":"28836"},{"last_name":"Rustemovic","first_name":"D.","full_name":"Rustemovic, D."},{"last_name":"Khatibi","first_name":"Arash","full_name":"Khatibi, Arash","id":"43538"}],"publication_identifier":{"isbn":["3-936338-73-6"]},"title":"Reduction of required storage capacities for a 100% renewable energy supply in Germany, if new PV systems are installed with east-west tracking systems at increased elevation angles","year":"2020","publication_status":"published","date_updated":"2022-01-06T13:43:51Z","language":[{"iso":"eng"}],"doi":"10.4229/EUPVSEC20202020-6BV.5.10"},{"user_id":"97359","volume":19,"page":"2428-2468","_id":"33263","publisher":"Society for Industrial & Applied Mathematics (SIAM)","status":"public","external_id":{"arxiv":["2006.08073"]},"citation":{"mla":"Nijholt, Eddie, et al. “Quiver Representations and Dimension Reduction in Dynamical Systems.” <i>SIAM Journal on Applied Dynamical Systems</i>, vol. 19, no. 4, Society for Industrial &#38; Applied Mathematics (SIAM), 2020, pp. 2428–68, doi:<a href=\"https://doi.org/10.1137/20m1345670\">10.1137/20m1345670</a>.","ama":"Nijholt E, Rink BW, Schwenker S.

Die Betriebsparamter der Ultraschallsysteme werden empirisch ermittelt, da derzeit keine systematische Analyse der Wechselwirkung zwischen Ultraschallwandler und Schallfeld sowie kein Verfahren zur Messung der Kavitationsaktivität ohne zusätzlichen Sensor existieren. Auf Basis einer experimentellen Analyse des betrachteten sonochemischen Reaktors wird ein Finite-Elemente-Modell aufgebaut, das die Wechselwirkung zwischen Schallfeld und Ultraschallwandler berücksichtigt. Die modellbasierte Analyse zeigt, dass wegen der akustischen Eigenschaften des Autoklavs nur direkt an der Sonotrode Kavitation entsteht. Die Wechselwirkung zwischen Ultraschallwandler und Schallfeld ermöglicht Aussagen über das Schallfeld und die Kavitationsaktivität auf Basis der Rückwirkung auf den Ultraschallwandler. Die lineare Schalldruckverteilung ermöglicht eine Prognose über die Verteilung von Kavitationszonen. Das beschriebene Modell liefert wertvolle Erkenntnisse für die Auslegung, Analyse und Skalierung sonochemischer Reaktoren. Auf Grund der rauen Prozessrandbedingungen ist die Applikation von Sensoren zur Überwachung der Kavitationsaktivität in vielen sonochemischen Prozessen nicht möglich. Zur prozessbegleitenden Messung der Kavitationsaktivität wird ein Verfahren entwickelt, das die Bewertung der Kavitationsaktivität durch Auswertung der Rückwirkung auf den Ultraschallwandler erlaubt. Das Messverfahren ermöglicht eine vorhersagbare und reproduzierbare Durchführung kavitationsbasierter Prozesse und stellt eine wichtige Erweiterung für bestehende und neue Ultraschallsysteme dar.","lang":"eng"}]},{"_id":"64018","language":[{"iso":"eng"}],"page":"662–672","volume":377,"doi":"10.1016/j.jcat.2019.07.049","user_id":"100715","author":[{"first_name":"Sarah","last_name":"Neumann","full_name":"Neumann, Sarah"},{"last_name":"Gutmann","first_name":"Torsten","full_name":"Gutmann, Torsten","id":"118165"},{"first_name":"Gerd","last_name":"Buntkowsky","full_name":"Buntkowsky, Gerd"},{"first_name":"Stephen","last_name":"Paul","full_name":"Paul, Stephen"},{"full_name":"Thiele, Greg","first_name":"Greg","last_name":"Thiele"},{"first_name":"Heiko","last_name":"Sievers","full_name":"Sievers, Heiko"},{"full_name":"Bäumer, Marcus","last_name":"Bäumer","first_name":"Marcus"},{"last_name":"Kunz","first_name":"Sebastian","full_name":"Kunz, Sebastian"}],"year":"2019","status":"public","title":"Insights into the reaction mechanism and particle size effects of CO oxidation over supported Pt nanoparticle catalysts","intvolume":"       377","date_updated":"2026-02-17T16:14:45Z","date_created":"2026-02-07T16:02:06Z","type":"journal_article","keyword":["Solid state NMR","“Surfactant-free” platinum nanoparticles","CO oxidation","Particle size effect","Structure sensitivity"],"citation":{"ieee":"S.

However, the role of particle size and more specifically structure sensitivity in this reaction is still controversial. In the present study, colloidal “surfactant-free” Pt nanoparticles (NPs) in a size regime of 1–4 nm with narrow size distribution and control over particle size were synthesized and subsequently supported on Al2O3 to prepare model catalysts. CO oxidation was performed using Pt NPs catalysts with particles sizes of 1, 2, 3, and 4 nm at different reaction temperatures. It is shown that the reaction exhibits a particle size effect that depends strongly on the reaction conditions. At 170 °C, the reaction seems to proceed within the same kinetic regime for all particle sizes, but the surface normalized activity depends strongly on the particle size, with maximum activity for nanoparticles 2 nm in diameter. A temperature increase to 200 °C leads to a change of the kinetic regime that depends on the particle size. For Pt NPs 1 nm in diameter a reaction order of 1 for O2 was observed, indicating that O2 adsorbs molecularly and dissociates in a following step, which represents the generally accepted mechanism on Pt surfaces. The reaction order of −1 for CO demonstrates that the surface is saturated with CO under reaction conditions. With increasing particle size, the reaction orders of O2 and CO change. For particles 2 nm in size, an increase in temperature also results in reaction orders of 1 for O2 and −1 for CO; NPs of 3 and 4 nm, even at higher temperatures, show no clear kinetic behavior that can be explained by a single reaction mechanism. Instead, the Boudouard reaction between two adjacent adsorbed CO molecules was identified as an important additional reaction pathway that occurs preferentially on large particles and causes more complex kinetics."}],"extern":"1"},{"date_updated":"2022-01-06T06:50:46Z","author":[{"id":"64665","full_name":"Awais, Muhammad","first_name":"Muhammad","orcid":"https://orcid.org/0000-0003-4148-2969","last_name":"Awais"},{"id":"61186","full_name":"Ghasemzadeh Mohammadi, Hassan","last_name":"Ghasemzadeh Mohammadi","first_name":"Hassan"},{"id":"398","full_name":"Platzner, Marco","first_name":"Marco","last_name":"Platzner"}],"year":"2018","title":"An MCTS-based Framework for Synthesis of Approximate Circuits","status":"public","doi":"10.1109/VLSI-SoC.2018.8645026","user_id":"64665","language":[{"iso":"eng"}],"_id":"10598","page":"219-224","abstract":[{"lang":"eng","text":"Approximate computing has become a very popular design\r\nstrategy that exploits error resilient computations to achieve higher\r\nperformance and energy efficiency.
