The calculation of the solids conveying throughput is particularly important for extruders with a grooved feed section. In contrast to smooth barrel extruders the throughput of the entire plant is determined at the feed section. Various simplifications are necessary for an analytical modelling of the solids conveying, e.g. the classification into conveying cases, the assumption of solid block flow and the assumption of pressure anisotropy coefficients. In numerical simulations with the Discrete Element Method (DEM), which has recently been successfully used to describe solids conveying in smooth barrel extruders, the simplifications mentioned above are not taken into account. Here, the pellets are approximated as spherical particles or particles composed of spheres. Based on virtual overlaps, contact models and the solution of Newton's equations of motion, a more complex consideration of the pellet flow is possible. In each iteration step of the simulation, the particle velocities, contact forces and derived quantities, e.g. the mass throughput in the screw channel and the grooves or the radial pressure build-up along the grooved barrel can be evaluated. Therefore, a DEM simulation model can be investigated by means of statistical design of experiments in order to convert the target values into a metamodel by regression. Long computation times of numerical simulations will be avoided in this matter as well as too simple assumptions of analytical approaches. The influencing parameters to be simulated are divided into material, geometry and process parameters. Relevant material parameters are the coefficients of friction of the polymer-polymer and polymer-steel surface as well as the restitution coefficient and the particle diameter. The geometry is varied in the form of the screw diameter, the channel depth and pitch, the number of grooves and their width, depth and angle. By varying the angle, both conventional axial grooves and helical grooves are taken into account. Finally, the process parameters speed and backpressure are also considered in the simulations. In order to reduce the simulation effort, irrelevant parameters are identified in preliminary investigations. }}, author = {{Schöppner, Volker and Brüning, Florian}}, booktitle = {{Advances in Polymer Processing 2020: Proceedings of the International Symposium on Plastics Technology}}, editor = {{Hopmann, Christian and Dahlmann, Rainer}}, publisher = {{Springer}}, title = {{{Development of a Solids Conveying Throughput Model for Grooved Barrel Extruders based on Discrete Element Simulations}}}, year = {{2020}}, } @article{23868, author = {{Albrecht, Mirko and Bialaschik, Max and Gehde, Michael and Schöppner, Volker}}, isbn = {{978-3-96144-098-6 }}, journal = {{DVS CONGRESS 2020 - Große Schweißtechnische Tagung}}, publisher = {{DVS Media GmbH}}, title = {{{Einfluss der Materialschädigung auf die Schweißnahtqualität beim Warmgasstumpfschweißen von Polyamiden}}}, volume = {{365}}, year = {{2020}}, } @inproceedings{23873, author = {{Albrecht, Mirko and Bialaschik, Max and Gehde, Michael and Schöppner, Volker}}, location = {{Pretoria}}, title = {{{Hot gas welding – Influences of the tool design}}}, doi = {{10.1063/5.0029478}}, year = {{2020}}, } @article{24005, author = {{Brüggemann, Jan-Peter and Risse, Lena and Woodcock, Steven Clifford and Joy, Tintu David and Neumann, Johannes and Vidner, Jakub and Kullmer, Gunter and Richard, Hans Albert}}, issn = {{2666-4968}}, journal = {{Applications in Engineering Science}}, title = {{{Structural optimization of a wheel force transducer component for more realistic acquisition of vehicle load data and fracture mechanical evaluation}}}, doi = {{10.1016/j.apples.2020.100032}}, year = {{2020}}, } @inproceedings{24011, author = {{Joy, Tintu David and Kullmer, Gunter and Risse, Lena}}, location = {{Hamburg}}, pages = {{207--216}}, title = {{{Vorhersage der Rissinitiierung in 3D-Strukturen mit ADAPCRACK3D}}}, volume = {{DVM-Bericht 252}}, year = {{2020}}, } @inproceedings{24012, author = {{Kullmer, Gunter and Weiß, Deborah and Bauer, Benjamin and Richard, Hans Albert}}, location = {{Hamburg}}, pages = {{61--70}}, title = {{{Entwicklung einer Axialrissprobe zur Ermittlung von bruchmechanischen Kennwerten für Rohre}}}, volume = {{DVM-Bericht 252}}, year = {{2020}}, } @phdthesis{24014, author = {{Risse, Lena}}, publisher = {{Shaker Verlag}}, title = {{{Präoperative Studien zur Gestaltung von patientenspezifischen, medizinischen Hilfsmitteln}}}, volume = {{Band 21}}, year = {{2020}}, } @article{24016, author = {{Schraeder, Dirk Theodor and Geisen, Bärbel and Baumann, Dirk and Afaneh, Mamoun and Schafran, Tommy}}, journal = {{Orthopädie Technik}}, pages = {{52--57}}, title = {{{Plastisch- chirurgische Verfahren modifiziert nach Lexer zur Versorgung des Diabetischen Fußsyndroms in der Technischen Orthopädie – ein Standard im Hospital Geseke}}}, volume = {{71 (8)}}, year = {{2020}}, } @inproceedings{20301, author = {{Günter, Heinrich and Meschut, Gerson}}, booktitle = {{73rd IIW Annual Assembly and International Conference}}, title = {{{Joining of high-strength steel grades in lightweight structures using single-stage resistance element welding on conventional resistance spot welding machines}}}, year = {{2020}}, } @inproceedings{20316, author = {{Krüger, Christopher and Schmolke, Tobias and Merdivan, David and Spohr, Sebastian and Urban, Peter and Meschut, Gerson}}, location = {{Aachen}}, title = {{{Concept Development for a Functional Integrated Lightweight Battery Housing with Special Consideration of the Joining Technology}}}, year = {{2020}}, } @book{20318, author = {{Göddecke, Johannes and Meschut, Gerson and Gude, Maik and Lieberwirth, Holger and Tekkaya, Erman and Zaeh, Michael and Stegelmann, Michael and Müller, Michael and Böhme, Kurt and Krampitz, Thomas and Zöllner, Mareen and Hahn, Marlon and Schmitz, Fabian and Hofer, Andreas and Grohmann, Sandra}}, isbn = {{978-3867806435}}, pages = {{82}}, publisher = {{Plattform FOREL}}, title = {{{FOREL-Wegweiser: Handlungsempfehlungen für den ressourceneffizienten Leichtbau }}}, year = {{2020}}, } @inproceedings{20321, author = {{Göddecke, Johannes and Meschut, Gerson and Teutenberg, Dominik and Ummenhofer, Thomas and Albiez, Matthias and Damm, Jannis and Matzenmiller, Anton and Kötz, Fabian}}, booktitle = {{20.
