    Sammanfattning : En växande medvetenhet om miljöfrågor i kombination med den ökade produktiviteten och effektiviteten som skapas av automation och digitalisering har lett till ett växande intresse för autonoma leveransrobotar. TerraGo Deliveries utvecklar eldrivna autonoma leveransrobotar med fokus på matleveranser. LÄS MER

  3. 2. Correlation between microstructure and fatigue cracks in cast aluminium alloy A205

    Kandidat-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Max Holmberg; Pontus Sundberg; [2022]
    Nyckelord :Aluminium Alloy A205;

    Sammanfattning : Materials research in the aerospace industry is, among other things, focused on reducing the weight and increasing the life of components. Materials with high strength and long lifespan are therefore examined. LÄS MER

  4. 3. Laser Arc Hybrid Welding of Thicker 6000-series Aluminium Alloy : Laser-MIG butt welding of 8 mm 6082-t6

    Master-uppsats, KTH/Industriell produktion

    Författare :Björn Lindeberg Nilsson; [2022]
    Nyckelord :;

    Sammanfattning : Laser arc hybrid welding presents many benefits but has many parameters that must be optimised for it to work. It becomes even more challenging when welding thicker aluminium with the process. Welding of thicker aluminium alloys involves a lot of different challenges, on itself. LÄS MER

  5. 4. Non-Linear strain paths in Sheet Metal Forming

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

    Författare :Anton Eriksson; [2021]
    Nyckelord :Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

    Sammanfattning : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. LÄS MER

  7. 5. Determining the Influence of the Type of Shielding Gas during Additive Manufacturing of an Aluminum Alloy by Monitoring the Process Qualitatively and Analyzing Process Byproducts Quantitatively

    Master-uppsats, KTH/Materialvetenskap

    Författare :Stefanie Desiree Kleemeyer; [2021]
    Nyckelord :additive manufacturing; PBF-LB M; aluminum; shielding gas; argon; nitrogen; helium; carbon dioxide;

    Sammanfattning : This thesis analyzes the influence of process gases on the formation and the characteristics of process byproducts that emerge during additive manufacturing of an aluminum alloy belonging to the 2000 series.  In order to address the influence, four pure gases, argon, nitrogen, helium, and carbon dioxide, were used as a shielding gas on the same parameter sets.
