  1. 1. Visualization, modeling and consequences of residual stresses in glass frit sealing of a UV light source

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Vilma Hurtigh Grabe; [2023]
    Keywords : bonding; micro system; glass frit; sealing; finite element; modeling; glass; mikrosystem; sammanfogning; glasfog; fog; finita element; modellering; glas;

    Abstract : PureFize Technologies AB develops and manufactures a broadband ultraviolet (UVC) light technology device that is mercury-free and based on nanotechnology, using the principle of field emission. The light source is made of Ti and glass, which are hermetically bonded, using a low-temperature glass frit, at elevated temperatures. READ MORE

  3. 2. Modelling of a Glued Bolt Joint in Finite Element

    University essay from KTH/Hållfasthetslära

    Keywords : Solid Mechanics; finite element method; adhesive; bolt; hybrid joint; Hållfasthetslära; finita element metoden; lim; skurv; hybrid förband;

    Abstract : This report presents a master thesis project at KTH at the school of Engineering Science. The project is done in collaboration with ABB Robotics, a company who develops industrial robots. A robot consists of several parts and the last structural part is the wrist. READ MORE

  4. 3. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

    University essay from KTH/Hållfasthetslära

    Author : Ludvig Dahlin; Ebba Larsson Regnström; [2022]
    Keywords : FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

    Abstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

  5. 4. Modelling of air-gap harmonic torques and its impact on vibrations in electric drivetrains : Modelling interaction between electromagnetics and vibration of an electrical machine

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Dhiyanesh Radhakrishnan; [2021]
    Keywords : Electro-Magnetics; Eigenfrequency; Electrical Machine; Multi-Body Dynamics; Displacement; machine vibrations; Elektromagnetik; Eigen frekvens; Elektrisk maskin; Flerkropps dynamik; Förskjutning; maskin vibrationer;

    Abstract : In this report, the effect of external torque injection of a particular phase and frequency was analyzed using an induction motor assembly consisting of a prototype of an induction motor and a flexible mounting arrangement. The eigenfrequencies of the several components that make up the construction of the induction machine assembly are found out both by analytical and FEM methods. READ MORE

  6. 5. Modelling masonry spires : An investigation

    University essay from KTH/Betongbyggnad

    Author : Dennis Lillemo; [2021]
    Keywords : Abaqus; Concrete damage plasticity; Finite element method; Limit analysis; Macro-modelling; Masonry; Masonry spire; Nonlinear material; Salisbury Cathedral; Abaqus; Concrete damage plasticity; Finita elementmetoden; Gränsanalys; Makromodellering; Murverk; Murad tornspira; Icke-linjärt material; Katedralen i Salisbury;

    Abstract : Masonry spires are a typical part of church architecture. Since it is rare that masonry is used as a load-bearing material in the western world today, it is important to maintain and increase the knowledge of modelling masonry structures both from a maintenance point of view and to build new masonry structures.
