  • Quentin, Lorenz; Beermann, Rüdiger; Pösch, Andreas; Reithmeier, Eduard; Kästner, Markus (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    We present a fringe projection system to measure glowing hot hybrid components in between production processes. For this a high power green light projector, based on TI DLP technology, is used to create the highest possible ...
  • Matthias, Steffen; Kästner, Markus; Reithmeier, Eduard (London : IOP, 2018-08-01)
    Optical measuring devices are widely used in industrial production and maintenance processes. With increasing integration, the accessibility of functional elements inside machines is limited for measuring devices. In order ...
  • Loftfield, Nina; Kästner, Markus; Reithmeier, Eduard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    A critical factor of endoprostheses is the quality of the tribological pairing. The objective of this research project is to manufacture stochastically porous aluminum oxide surface coatings with high wear resistance and ...
  • Dröder, Klaus; Karpuschewski, Bernhard; Uhlmann, Eckart; Arrabiyeh, Peter A.; Berger, Daniel; Busemann, Sarah; Hartig, Jörg; Madanchi, Nadine; Mahlfeld, Georg; Sommerfeld, Christian (Berlin : Springer, 2020)
    Milling of ferrous metals is usually performed by applying cemented carbide tools due to their high hardness, temperature and wear resistance. Recently, ceramic tool materials have been on the rise and enhanced the efficiency ...
  • Ohrdes, H.; Ille, I.; Twiefel, J.; Wallaschek, J.; Nogueira, R.; Rosenwinkel, K.-H. (Amsterdam [u.a.] : Elsevier Science, 2018)
    Sonochemical processes applied to wastewater treatment have an influence on the behavior of ultrasonic systems. This is especially due to the load characteristic of the sonochemical process itself and the temperature ...
  • Lu, Xiaolong; Wang, Zhiwen; Shen, Hui; Zhao, Kangdong; Pan, Tianyue; Kong, Dexu; Twiefel, Jens (Basel : Molecular Diversity Preservation International (MDPI), 2020)
    Micro underwater vehicles (MUVs) have been highlighted recently for underwater explorations because of their high maneuverability, low price, great flexibility, etc. The thrusters of most conventional MUVs are driven by ...
  • Schröder, Jörg; Wick, Thomas; Reese, Stefanie; Wriggers, Peter; Müller, Ralf; Kollmannsberger, Stefan; Kästner, Markus; Schwarz, Alexander; Igelbüscher, Maximilian; Viebahn, Nils; Bayat, Hamid Reza; Wulfinghoff, Stephan; Mang, Katrin; Rank, Ernst; Bog, Tino; D’Angella, Davide; Elhaddad, Mohamed; Hennig, Paul; Düster, Alexander; Garhuom, Wadhah; Hubrich, Simeon; Walloth, Mirjam; Wollner, Winnifried; Kuhn, Charlotte; Heister, Timo (Berlin [u.a.] : Springer, 2020)
    In this contribution we provide benchmark problems in the field of computational solid mechanics. In detail, we address classical fields as elasticity, incompressibility, material interfaces, thin structures and plasticity ...
  • Schwack, Fabian; Bader, Norbert; Leckner, Johan; Demaille, Claire; Poll, Gerhard (Amsterdam [u.a.] : Elsevier Science, 2020)
    Pitch bearings in wind turbines are affected by reciprocating motion due to pitch control. The combination of oscillating operation, high loads, and mixed lubrication often leads to wear. Grease lubricants in wind turbine ...
  • Mullo, Santiago D.; Pruna, Edwin; Wolff, Julius; Raatz, Annika (Amsterdam : Elsevier B.V., 2019)
    Typically, disassembly forces are unknown due to high forces or high temperatures during product operation, where assembly connections solidify. For the regulation of disassembly forces a controller is developed. The ...
  • Wriggers, Peter; Hudobivnik, Blaz; Aldakheel, Fadi (Berlin [u.a.] : Springer, 2020)
    The virtual element method is a lively field of research, in which considerable progress has been made during the last decade and applied to many problems in physics and engineering. The method allows ansatz function of ...
  • Wienke, A.; Hoffmann, G.-A.; Koch, J.; Jäschke, P.; Overmeyer, Ludger; Kaierle, Stefan (Amsterdam : Elsevier B.V., 2020)
    An efficient and low-cost approach to manufacture Opto-Mechatronic Interconnect Devices will be obligatory to handle the strongly increasing amount of data. The presented approach is based on a flexographic printing process. ...
  • Ahrens, M.; Fischer, R.; Dagen, M.; Denkena, Berend; Ortmaier, Tobias (Amsterdam : Elsevier, 2013)
    Using conventional grinding wheels, wheel-sided chatter vibration is one of the limiting factors in terms of productivity and surface finish. Initial vibration related to the dynamic behavior of the machine tool copy on ...
  • Eilers, Hubertus (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2011)
    [no abstract]
  • Marhenke, Torben; Sanabria, Sergio J.; Chintada, Bhaskara Rao; Furrer, Roman; Neuenschwander, Jürg; Goksel, Orcun (Basel : MDPI AG, 2019)
    Medical ultrasonic arrays are typically characterized in controlled water baths using measurements by a hydrophone, which can be translated with a positioning stage. Characterization of 3D acoustic fields conventionally ...
  • Hellmich, Bernd (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2008)
    [no abstract]
  • Ahrens, M.; Dagen, M.; Denkena, Berend; Ortmaier, Tobias (Amsterdam : Elsevier, 2016)
    Using conventional grinding wheels, self-excited vibrations are one of the most limiting factors in terms of productivity and process stability in cylindrical plunge grinding. Depending on the dynamic behavior of the ...
  • Denkena, Berend; Gümmer, Olaf (Amsterdam : Elsevier, 2013)
    Within the Collaborative Research Centre 489 at the Leibniz Universitaet Hannover a new and innovative process chain for the manufacture of crankshafts is being investigated. By burr-free and near-net-shaped precision ...
  • Fast, Jacob Friedemann; He, Jiazhen; Ortmaier, Tobias; Jungheim, Michael; Ptok, Martin; Kahrs, Lüder Alexander (Berlin : De Gruyter, 2019)
    The laryngeal adductor reflex (LAR) is an important protective function of the larynx to prevent aspiration and potentially fatal aspiration pneumonia by rapidly closing the glottis. Recently, a novel method for targeted ...
  • Nyhuis, Peter; Vogel, Markus (Bingley : Emerald Group Publishing Ltd., 2006)
    Purpose - To provide a model for precise logistic controlling of one-piece flow processes and for the description of the interactions between logistic performance measures. The developed method can help manufacturing ...
