  1. 26. Development of a DEM-FEM framework for infrastructure simulations

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Anita Ullrich; [2022-09-20]
    Nyckelord :;

    Sammanfattning : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. LÄS MER

  3. 27. A parametric study of the static and dynamic performance of timber arch footbridges with different hanger configurations

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :ALEJANDRO GARCÍA GARCÍA; [2022]
    Nyckelord :Arch bridges; footbridge dynamics; critical load; bridge typology; parametric study;

    Sammanfattning : The influence of the hanger configuration in the arch and deck bending moments under asymmetric loads is widely used nowadays for improved designs of arch bridges. In this work, by means of a parametric study, those hanger configurations that most efficiently increase both the natural frequencies and buckling factors are identified, simultaneously evaluating the dynamic and static performance of timber arch footbridges.

  4. 28. Global Analysis of a Tall Timber- Concrete Hybrid Structure Subjected to Wind Load : A Parametric Study of Different Hybrid Solutions

    Master-uppsats, KTH/Betongbyggnad

    Författare :Clara Youssef; Meriam Basilious; [2022]
    Nyckelord :;

    Sammanfattning :   Tall timber structures have received more attention in recent times as building withtimber contributes to environmental benefits in comparison to other building materials.Timber- concrete hybrid structures have become an alternative as previous investigationshave shown that building tall timber buildings implies complexities with regardsto sufficient stiffness and discomfort for occupants.

  5. 29. Electric Road Systems: A case study on the bridge of Öresund

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Jakob Svensson; [2022]
    Nyckelord :Electric road systems; Transportation; Electric Vehicle; Technology and Engineering;

    Sammanfattning : Combustion of fossil fuels is single-handedly the largest contributor of global warming. The transportation sector is responsible for about a third of the greenhouse gas emissions yearly in Sweden. In turn, road traffic makes up the largest share within the transportation. LÄS MER

  7. 30. Material selection and topology optimization of a shift fork for metal 3D printing

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Rahul Amaralapudi Bala Vardha Raju; Raja Surya Mahesh Thammisetty; [2022]
    Nyckelord :Additive manufacturing; Topology optimization; Finite Element Analysis; SIMP; Generative design;

    Sammanfattning : In collaboration with Kongsberg Automotive, the thesis focuses on material selection and redesigning the shift fork for additive manufacturing using topology optimization. The shift fork is a component in the gear shifting mechanism in the automotive industry. The current shift fork at Kongsberg is manufactured from aluminum using die-casting. LÄS MER
