  1. 21. Computationally Efficient Methods in Topology Optimization

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Vilmer Dahlberg; [2022]
    Nyckelord :Topology Optimization; Eigenfrequency; Eigenmode; Reduced Order Model; Sensitivity Analysis; Deflation; Technology and Engineering;

    Sammanfattning : In topology optimization, iterative, gradient-based methods are used to find the material distribution of structures which maximizes some objective function, typically the structures' stiffness, or in some cases the fundamental frequency. Finite element analysis is used to compute the structural response in each iteration, leading to large systems of equations. LÄS MER

  3. 22. Selection of a product component for topology optimization and additive manufacturing

    Master-uppsats, Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Författare :Marcus Svensson; [2021]
    Nyckelord :Product development; Semi structured interview; Component selection; Topology Optimization; Additive Manufacturing; Finite Element Analysis; Computer Aided Engineering;

    Sammanfattning : This is a master thesis research on how to select the right components in a product, considering reducing the weight with topology optimization (TO) and adaption for additive manufacturing (AM). It is well established that manufacturing of complex structures can be achieved with AM, the possibility of integrating assembled components and improve features will therefore be investigated.

  4. 23. Structural Investigations of Novel Heliostat Designs based upon the Hydraulic Infinite Linear  Actuator (HILA)

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Venkata Nikhil Nandigama; [2021]
    Nyckelord :Structural Analysis; Heliostat; Mechanics; Topology optimization; Finite element methods; concentrated solar power; renewable energy.;

    Sammanfattning : A heliostat is a device that reflects the sun’s rays to a stationary object. There are two different types of heliostat serial and parallel type. The most used is the serial type of heliostat with Azimuthal-Elevation(Az-El) drive. LÄS MER

  5. 24. Isogeometric analysis as a tool for large deformation shape optimization

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Författare :Max Kurki; [2021]
    Nyckelord :IGA; NURBS; Shape optimization; Large deformations; Topology optimization; Technology and Engineering;

    Sammanfattning : The framework for isogeometric analysis (IGA) is presented, especially the construction and use of non-uniform rational B-splines (NURBS) to represent geometry, and a method utilizing IGA for structural optimization both for linear elastic and non-linear elastic deformations is implemented. Topology optimization of a linear elastic cantilever is performed, showing that IGA is inecient for topology optimization. LÄS MER

  7. 25. Weight optimization of a harvesting head

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Anas Darwich; [2021]
    Nyckelord :Harvester; Forwarder; Topology optimization; Main plate; Skördare; Skrotare; Topologi optimering; Huvudplatta;

    Sammanfattning : With the development of the deforestation industry and the increased demand for sawn goods and woods over the world, created a need for more efficient harvesting methods, a need that was represented by mechanized harvesters and forwarders in forestry. These machines are efficient when it comes to mass production and can cut and delimb trees of all sizes and kinds. LÄS MER
