  1. 6. 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.

  3. 7. FE Modeling of Cushion 3D Motion for Sheet Metal Forming Simulation

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Jagdish Jadhav; [2019]
    Nyckelord :Finite Element analysis; contact pressure; sheet metal forming; LS-DYNA.;

    Sammanfattning : Nowadays FE-simulations for sheet metal forming process are used to reduce the tryout phase in automotive industries. But the complex forming simulation processes are very challenging. One of the challenges is to create an FE-model which can be used to analyze the effects of cushion motion on the forming process.

  4. 8. Industrial Sheet Metal Forming Simulation with Elastic Dies

    Uppsats för yrkesexamina på avancerad nivå, 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.

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

    Uppsats för yrkesexamina på avancerad nivå, 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

  7. 10. Case Study: Production and OEE improvement for an 800 tons stamping press

    Master-uppsats, Akademin för innovation, design och teknik

    Författare :Aurélien Narses; [2013]
    Nyckelord :Overall Equipment Effectiveness OEE ; Single Minute Exchange of Dies SMED ; 5’s; pressing equipment; Lean Manufacturing;

    Sammanfattning : The actual industrial development linked to the financial situation over the world lead automotive and other companies to expand their production level to stay competitive. Changing an organization to raise its production or profit is not a one day journey, but requires some steps. LÄS MER
