  1. 21. Characterisation of Packaging Material Surfaces

    University essay from Lunds universitet/Materialteknik

    Author : Andreas Ingelström; Mikael Ek; [2017]
    Keywords : packaging material; surface texture; focus variation; 3D measurement; pattern transfer; glossiness; friction; Technology and Engineering;

    Abstract : As the packaging material (PM) becomes better defined from the results of technical development, its processing stages will be of greater complexity. The nip process is an example of one vital step in the lamination coating of PM, and this process is studied in the present thesis by analysing the surfaces of chill rollers (CR) and PM. READ MORE

  3. 22. Catalytic ortho- to parahydrogen conversion in liquid hydrogen

    University essay from Lunds universitet/Materialteknik

    Author : Emil Karlsson; [2017]
    Keywords : Orthohydrogen; Parahydrogen; Catalytic conversion; IONEX; OXISORB; Kinetics; ESS; Hydrogen; Liquid hydrogen; Moderator; Technology and Engineering;

    Abstract : The kinetics of the catalytic conversion of ortho- to parahydrogen was studied for the two catalysts, IONEX® and OXISORB®. The study also involved the optimization of an experimental technique for the conversion of orthohydrogen in a static setup. READ MORE

  5. 24. Thermo-mechanical Fatigue of Electrical Insulation System in Electrical machine

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Ahmed Elschich; [2017]
    Keywords : Thermal mechanical fatigue; Thermo-mechanical stress; electrical machine windings; electrical insulation system; slot insulation; slot liner; groundwall insulation; conductor insulation; turn insulation; stator;

    Abstract : Electrical machines in electrified heavy-duty vehicles are subjected to dynamic temperature loadings during normal operation due to the different driving conditions. The Electrical Insulation System (EIS) in a stator winding is aged as an effect of these dynamic thermal loads. READ MORE

  6. 25. Master thesis within light warhead for support weapon : Investigation of defects, methods and requirement specifications in order to get a shell body shatter free

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Adam Jansson; [2016]
    Keywords : warhead; support weapon; shell body; shatter free; defect; method; carbon fibre; epoxy; crack; delamination; porosity; CFRP; CFRE; NDT; verkansdel; understödsvapen; granathylsa; splitterfri; defekt; metod; kolfiber; epoxi; spricka; delaminering; porositet; OFP;

    Abstract : At launching the shell body, especially the backplane of the shell body, will be exposed to very high stresses due to acceleration, pressure and increased temperature from the propellant combustion. Defects in the shell body could in worst case for example result in high temperature gas leakage into the warhead and thereby ignite the explosives before exiting the launcher. READ MORE
