  1. 31. Fatigue analysis of laser welded hairpins in electric car motors

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Francisco Martín Ruiz; Imanol Iribar Rodriguez; [2022]
    Keywords : ;

    Abstract : Hairpins are copper filaments used in the windings in the stators of electric motors in modern times. For the motor to work, they have to be welded in pairs, normally with laser welding. Studying the fatigue response of the joint of hairpins welded with a set of values of laser welding process parameters is the main objective of this project. READ MORE

    Abstract : Under de senaste åren, på grund av överanvändningen av icke förnybara resurser har den ekologiska miljön på jorden påverkats allvarligt. I takt med detta ökade oron bland människor om att resurserna skulle ta slut. Därför är det nödvändigt att utveckla och använda mer miljövänliga förnybara resurser. READ MORE

  5. 34. Novel materials from lignocellulosic sources- can they replace thermoplastics?

    University essay from KTH/Fiber- och polymerteknologi

    Author : Emmy Albinsson; Helina Tafesse Belachew; Jasmin Swaich; Hannah Juhlin; [2021]

    Abstract : Plastic waste is a severe environmental problem in today's society which has been noticed and discussed during the last couple of years. A constant increase of production over the last decades hasled to a large amount of plastic waste ending up in oceans as microplastics. READ MORE

  6. 35. Tensile strength reduction for insufficient thread engagement A FEM study of a wall-shoe assembly

    University essay from KTH/Hållfasthetslära

    Author : Henrik Larsson Sevon; [2021]
    Keywords : Solid Mechanics; Tensile strength; Wall-shoe; Thread engagement; Hållfasthetslära; Draghållfasthet; Väggsko; Gängingrepp;

    Abstract : The purpose of this master thesis is to determine whether or not it exist, a model that can describethe reduction in strength, due to missing threads in a bond between a bolt and nut. And how thereduction in strength might effect a wall-shoe assembly, used to connect a wall to another wall or aconcrete base plate. READ MORE
