  1. 1. Extraction of tool reaction forces using LS-DYNA and its use in Autoform sheet metal forming simulation

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Esbjörn Zachén; [2019]
    Nyckelord :Sheet Metal Forming; Stamping Die; blank holder; Structural Analysis; Finite Element Simulation;

    Sammanfattning : In product development there is still potential to decrease lead times with faster and more accurate simulations. The objective of this thesis was to study whether Finite Element (FE) simulations using explicit LS-DYNA to extract reaction forces from sheet metal forming tools during forming, could be used to improve existing FE models in sheet metal forming software AutoForm.

  2. 2. AP&T Machine and Line Usability : A usability analysis of stand-alone machines and production lines at AP&T

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Fanny Åkerström; [2019]
    Nyckelord :Usability; user experience; user needs; human-machine interaction; press hardening; industry; digitalization; automation; production solution; development; Användarvänlighet; användarupplevelse; användarbehov; HMI; presshärdning; industri; digitalisering; automation; produktionslösning; utveckling;

    Sammanfattning : Automation and digitalization are developing at a high pace and it is important to keep the focus on human-machine interaction. It is becoming more and more important that the usability in machines and lines is related to the development so that the performance and availability of the production processes in the industry are not adversely affected.

  3. 3. Industrial Sheet Metal Forming Simulation with Elastic Dies

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Markus Lind; Viktor Sjöblom; [2018]
    Nyckelord :Elastic Stamping Dies; FEA; LS-Dyna; Sheet Metal Forming; Structural Analysis;

    Sammanfattning : As part of the development process for new stamping dies, in the automotive sheet metal forming (SMF) industry, the majority of all forming operations are simulated with the Finite Element Method (FEM) before the dies are manufactured. Today, these simulations are conducted with rigid tools under the assumption that there are no tool deformations.

  4. 4. Investigation of factors affecting cracking during forming of truck cab body parts

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Evelina Salomonsson; [2018]
    Nyckelord :;

    Sammanfattning : Sheet metal forming is a technique widely used in todays industries as it enables fast transformation of metal sheets into parts of various shapes and sizes. Volvo GTO EBM in Umeå uses sheet metal forming in their production of truck cab body parts, and a challenge common for all industries using this technique is to avoid cracking in the formed metal.

  5. 5. Press Measurements and Virtual Rework of Stamping Dies

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Einar Palsson; Mårten Hansson; [2017]
    Nyckelord :Virtual Rework; Inverse Modeling; ARAMIS Digital Image Correlation DIC ;

    Sammanfattning : Stamping dies are used in the Sheet Metal Forming (SMF) process for manufacturing of car body parts. The lead time for design and manufacturing of a stamping die is long, and therefore costly. LÄS MER
