  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. Preparing parts for Wire and Arc Additive Manufacturing (WAAM) and net-shape machining

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Isak Koskenniemi; [2019]
    Keywords : Additive manufacturing; AM; Wire and Arc Additive Manufacturing; WAAM;

    Abstract : WAAM is a relatively unexplored additive manufacturing method. Although research in this area has been performed for some years and the hardware is relatively cheap, the method is not widely used. As the name suggest, it uses wire and an arc welding equipment to deposit beads on top of each other to create a geometry. READ MORE

  3. 3. Natural frequency and transient dynamic analysis of vehicle integrated RBS 70 NG system

    University essay from Karlstads universitet

    Author : Ammar Kadhim; [2018]
    Keywords : Natural frequency and transient dynamic analysis;

    Abstract : Abstract This study is a master thesis in mechanical engineering at Karlstad’s University that treats operation disturbances that occur during the use of a vehicle integrated air-defense system called Robot-system 70 New Generation (RBS 70 NG) in cooperation with SAAB Dynamics AB. RBS 70 NG is a man-portable air-defense system (MANPADS) which is designed for anti-aircraft warfare and can be used in all climate zones. READ MORE

  4. 4. Design Analysis and Optimization of Front Underrun Protection Device

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Anil Sharma; [2018]
    Keywords : Finite Element Method; Topology Optimization; Crash Analysis.;

    Abstract : Under-running of passenger vehicle is one of the major parameters to be considered during the design and development of truck chassis. Front Under-run Protection Device (FUPD) plays an important role in avoiding under-running of vehicles from front side of a truck. READ MORE

  5. 5. Development of a Methodology for Efficient FEM Pre-processes to Aid Simulation-driven Design

    University essay from Linköpings universitet/Maskinkonstruktion; Linköpings universitet/Maskinkonstruktion

    Author : Mattias Bäckman; Josef Kling; [2018]
    Keywords : FEM; Welds; Automation; MDO; HyperMesh; Simulation-driven design; Design Automation; Pre-processes; Mesh;

    Abstract : With both tougher competition and legislations, companies always strive to improve their products while cutting unnecessary costs. This master’s thesis investigates if the after-treatment systems department at the heavy-duty vehicle company Scania CV AB in Södertälje, Sweden can improve their development process by implementing automated FEM pre-processes for welded sheet metal components.
