  1. 1. Resistance Element Welding of Ultra High Strength Steel to Aluminium

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Malte Eriksson; [2023]
    Nyckelord :;

    Sammanfattning : The automotive industry strives towards decreased vehicle weight in order to decrease green house gas emissions. To create lighter vehicles, new lighter materials need to be implemented. One issue with new materials is that the traditional joining methods in many cases meet their limitations. LÄS MER

  3. 2. Projection Nut Welding to High- and Ultra-high Strength Steels

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Love Englund; [2023]
    Nyckelord :mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

    Sammanfattning : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. LÄS MER

  4. 3. Sandwich Design of a Platform Lift Floor

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Ruizhi Zhao; [2022]
    Nyckelord :Aluminium honeycomb sandwich; Fatigue analysis; Sandwich design; Sandwich joint design; SolidWorks simulation; Bikakesanalys; Bikakemönster sandwich; Sandwich design; SolidWorks-simulering; Utmattningsanalys;

    Sammanfattning : Mobility is a symbol of dignity. A platform lift enables everyone of different physical abilities to move vertically with ease. Currently, the platform lift by Aritco Lift is made of steel sheet metal. It is heavy, thus difficult to handle. LÄS MER

  5. 4. Modernized 6 and 10-ton Dock Levelers

    Master-uppsats, Lunds universitet/Innovation

    Författare :Viola Nilsson; Rebecka Karlsson; [2021]
    Nyckelord :Dock leveler; FEM; stress; sheet metal; load case; Technology and Engineering;

    Sammanfattning : This Master Thesis is made in collaboration with ASSA ABLOY Entrance Systems and addresses the issues and problem areas of two dock leveler models; 60 kN and 100 kN to find a new improved design. After the following product development process, a new concept was created which could withstand applied forces exceedingly. LÄS MER

  7. 5. Saltwater Intrusion in Fractured Crystalline Bedrock Aquifer. - A Case Study on Koster Islands, SW Sweden

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Sibhat Afewerki; [2019-10-30]
    Nyckelord :saltwater intrusion; fractured bedrock aquifers; DRASTIC; vulnerability mapping; Koster Islands; slatvattenintrång; Akvifer i uppsprucken berggrund; sårbarhetskartläggning; Kosteröarna;

    Sammanfattning : Saltwater intrusion (SWI) is one of the significant threats in many coastal areas, mainly driven by anthropogenic hazards (over-pumping) and climate change (sea level rise). So far, there have been extensive research and techniques to understand and minimize SWI. LÄS MER
