  1. 1. Metamodelling of a Finite Element Analysis of a Drilling Process with Replaceable Inserts

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Samy Akrouh Ettaghadouini; [2019]
    Nyckelord :drilling; speed; feed; CAD; FEM; simulations; metamodel; neural network; optimization;

    Sammanfattning : The aim of this project is to create a metamodel from a drilling tool with replaceable inserts from FEA of the machining process using MATLAB and ABAQUS. This report contains research in drilling and in metamodeling using neural networks and the work from the design of the CAD, through FEA and simulations, to the metamodeling, excluding the optimization.

  2. 2. Probabilistic non-linear finite element analysis of concrete buttress dams

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Adrian Ulfberg; [2019]
    Nyckelord :ATENA; FREET; SARA; probabilistic; numerical; Kalhovd; FEA; FEM;

    Sammanfattning : Assessment of concrete buttress dams today consists of using analytical methods to investigate the stability in different failure modes. However, they simplify the problem at hand and neglect certain important features linked to geometry and thus not truthfully appraise the structures real stability. LÄS MER

  3. 3. Testrigg för Tätning av Marin Transmission

    M1-uppsats, Mälardalens högskola/Innovation och produktrealisering; Mälardalens högskola/Innovation och produktrealisering

    Författare :Michael Eriksson; Douglas Munguia Chang; [2019]
    Nyckelord :;

    Sammanfattning : The aim of the project is to create a concept proposal on a fundamental construction of a test equipment for Volvo Penta, where observations of their seals can be carried out. The current day problem is the difficulty to obtain consistent test results during test experiments in the oceans, due to the test environment never being identical to another.

  4. 4. Industrial Sheet Metal Forming Simulation with Elastic Dies

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Markus Lind; Viktor Sjöblom; [2018]
    Nyckelord :Elastic Stamping Dies; FEA; LS-Dyna; Sheet Metal Forming; Structural Analysis;

    Sammanfattning : As part of the development process for new stamping dies, in the automotive sheet metal forming (SMF) industry, the majority of all forming operations are simulated with the Finite Element Method (FEM) before the dies are manufactured. Today, these simulations are conducted with rigid tools under the assumption that there are no tool deformations.

  5. 5. A micro-CT investigation of density changes in pressboard due to compression

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Johan Stjärnesund; [2018]
    Nyckelord :Micro computed tomography; μCT; pressboard; density; densification;

    Sammanfattning : Pressboard, a high-density cellulose-based product, is used both as load bearing structures and dielectric insulation in oil-filled power transformers. During transformer operation, mechanical forces and vibrations are applied on the material. LÄS MER
