  • Wellmann, Christian; Lillie, Claudia; Wriggers, Peter (Bingley : Emerald Group Publishing Ltd., 2008)
    Purpose - The paper aims to introduce an efficient contact detection algorithm for smooth convex particles. Design/methodology/approach - The contact points of adjacent particles are defined according to the common-normal ...
  • Schmidt, Matthias; Schäfers, Philipp (Wuhan : Scientific Research Publishing, 2017)
    This paper presents an approach for modelling the connection between the tasks of production planning and control (PPC) and a supply chain’s logistic objectives. Therefore a new production planning and control framework ...
  • Denkena, Berend; Grove, Thilo; Krödel, Alexander (Amsterdam : Elsevier, 2016)
    Due to the rising number of car variants, the production systems in automobile industry are driven by a strong demand for flexible production processes. In the production of thin-walled workpieces, forming and cutting ...
  • Abdellatif, Houssem; Heimann, Bodo (Cambridge : Cambridge University Press, 2008)
    The issue of motion planning for closed-loop mechanisms, such as parallel manipulators or robots, is still an open question. This paper proposes a novel approach for motion planning of spatial parallel robots. The framework ...
  • Denkena, Berend; Grove, Thilo; Ellersiek, L. (Amsterdam : Elsevier B.V., 2018)
    In this paper, a new tool concept suitable for simultaneous roughing and finishing operations is presented. The developed end mill has two radial recessed roughing teeth with a flank face chamfer and two sharp finishing ...
  • Bai, Fushi; Wang, Liang; Saalbach, Kai-Alexander; Twiefel, Jens (Basel : Molecular Diversity Preservation International (MDPI), 2018)
    Ultrasonic cavitation peening is an environmentally friendly technology to improve surface properties. In the traditional ultrasonic cavitation peening process, specimens have to be immersed in a liquid and temperature ...
  • Goldmann, Andreas; Sauter, Waldemar; Oettinger, Marcel; Kluge, Tim; Schröder, Uwe; Seume, Jörg R.; Friedrichs, Jens; Dinkelacker, Friedrich (Basel : MDPI AG, 2018)
    With the growth of aviation traffic and the demand for emission reduction, alternative fuels like the so-called electrofuels could comprise a sustainable solution. Electrofuels are understood as those that use renewable ...
  • Aboulfotoh, Noha; Twiefel, Jens (Basel : MDPI, 2018)
    This study presents theoretical investigations on the effectiveness criteria for piezoelectric energy harvesters (PEHs) under volume constraints. Firstly, the importance of the volume consideration is investigated. The ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Denkena, Berend; Flöter, F. (Amsterdam : Elsevier BV, 2012)
    In the re-contouring process of aircraft engine components, the unknown geometry and inhomogeneous material properties of the workpiece are major challenges. For this reason a new repair process chain is supposed which ...
  • Zhou, Shuwei; Zhuang, Xiaoying (Amsterdam : Elsevier, 2018)
    In this study, we present an adaptive phase field method (APFM) for modeling quasi-static crack propagation in rocks. Crack initiation due to positive strains is considered, and a numerical simulation is implemented using ...
  • Behrens, Bernd-Arno; Bouguecha, Anas; Vucetic, Milan; Chugreev, Alexander (Les Ulis : E D P Sciences, 2016)
    In the recent decades the finite element method has become an essential tool for the cost-efficient virtual process design in the metal forming sector in order to counter the constantly increasing quality standards, ...
  • Budziak, Kinga (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2015)
    This project evaluates the sutability and practicality of the program Athena Vortex Lattice (AVL) by Mark Drela. A short user guide was written to make it easier (especially for stu-dents) to get started with the program ...
  • Wolff, T.; Ernst, Benedikt; Seume, Jörg R. (Bristol : IOP Publishing Ltd., 2014)
    The length of wind turbine rotor blades has been increased during the last decades. Higher stresses arise especially at the blade root because of the longer lever arm. One way to reduce unsteady blade-root stresses caused ...
  • Frädrich, Thomas; Pachow-Frauenhofer, Julia; Fiege, Torsten; Nyhuis, Peter (Bingley : Emerald Group Publishing Ltd., 2011)
    Purpose - The purpose of this paper is to transfer the idea of changeability to a concrete technical application. Design/methodology/approach - Based on the definition of changeability on a factory level, a transformation ...
  • Schwerdt, Lukas; Hauptmann, Thomas; Kunin, Artsem; Seume, Jörg R.; Wallaschek, Jörg; Wriggers, Peter; Panning-von Scheidt, Lars; Löhnert, Stefan (Amsterdam : Elsevier BV, 2017)
    This paper presents an integrated methodology for the analysis of operationally-used turbine blades, incorporating aerodynamic and multiple structural simulations. In jet engines, blade rubbing and erosion lead to deviations ...
  • Gregorian, Hayk (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2019)
    Purpose - This bachelor thesis compares high-speed rail (HSR) transport with air transport. The investigation considers physical fundamentals, energy consumption, environmental impact, infrastructure and investment, market ...
  • Burzlaff, Marcus (Hamburg : Aircraft Design and Systems Group (AERO), Department of Automotive and Aeronautical Engineering, Hamburg University of Applied Sciences, 2017-12-13)
