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

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

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

    Abstract : 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

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Fanny Åkerström; [2019]
    Keywords : 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;

    Abstract : 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. Material modeling in Sheet Metal Forming Simulations : Quality comparison between comonly used material models

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Kevin nilsson; [2019]
    Keywords : AutoForm; Material model; Biaxial data; Tesnile test; AutoForm; Material modell; Biaxiella data; Dragprov;

    Abstract : In today's automotive industries, many different simulation programs are used to optimize parts before they come into production. This has created a market for complex material models to get the best possible approximation of reality in the simulation environment. READ MORE

  4. 4. Sheet Metal Forming Simulations with Elastic Dies: Emphasis on Computational Cost

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Sara Allesson; [2019]
    Keywords : Elastic Sheet Metal Forming Simulation; Computational Cost; Decomposition; LS-DYNA; Elastisk plåtformningssimulering; beräkningskostnad; dekomposition; LS-DYNA;

    Abstract : The car industry produces many of their car parts by using sheet metal forming, where one of the most time-consuming phases is the development and manufacturing of new forming tools. As of today, when a new tool is to be evaluated in terms of usability, a forming simulation is conducted to predict possible failures before manufacturing. READ MORE

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

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

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

    Abstract : 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.
