  1. 31. A simplified forging simulation tool: validation with finite element method

    University essay from Institutionen för teknik och samhälle

    Author : Omar Zini; [2013]
    Keywords : ;

    Abstract : Nowadays, the forging industry has a great importance in the fabrication of metallic parts. Therefore, new theoretical models, or modifications to others already existing, continuously appear to improve the process. New investigations culminated, recently, in equations designed to obtain the necessary pressure to forge a part. READ MORE

  4. 33. Speed dependent friction in bolt joints

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Arvid Blom; [2013]
    Keywords : Bolt joint; friction; Stribeck; speed dependent; load distributio; Skruvförband; friktion; Stribeck; hastighetsberoende; tryckfördelning;

    Abstract : Denna rapport undersöker hastighetsberoende friktionsbeteende i zinkpleterade 8.8 M12x1.75 skruvförband med en klämlängd på 82 mm och ett åtdragningsmoment på 120 Nm. Totalt 84 åtdragningar genomförs med nya skruvar, brickor och muttrar för varje åtdragning med utrustning tillhandahållen av Atlas Copco. READ MORE

  5. 34. Modeling and motion control of a pick and place machine with air bearings

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Elisabeth Amann; [2012]
    Keywords : ;

    Abstract : To minimize friction related heat generation Micronic Mydata is interested in the option of using air bearings in future surface mounting machines, such as the successors of today's pick and place machine. The axes of interest is the linear motions in the horizontal plane whose objective is to place a component in the correct position on a PCB. READ MORE

  6. 35. Modeling and Control of Friction Stir Welding in 5 cm thick Copper Canisters
