  1. 1. Sammanfogningsmetoder för metallprofiler - lådor och ramar

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Björn Rehnberg; Vincent Vallin Sälle; [2023]
    Nyckelord :;

    Sammanfattning : Joining of materials is a very popular area of research, as a result of its central role within modern industry. The automotive industry has seen an increase in demand for joining methods that can contribute to weight reduction and meet the criteria for strength, while co-existing with goals set for sustainable development for the future.

  3. 2. Plastic deformation of hot riveted joints acting in shear

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Victor Gard; [2023]
    Nyckelord :;

    Sammanfattning : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. LÄS MER

  4. 3. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Abhiroop Chatterjee; [2023]
    Nyckelord :;

    Sammanfattning : Bolted joints are important due to their energy dissipation property in structures,but the damping mechanism is also highly nonlinear and localized. The goal ofthis thesis is to develop an accurate method for modeling bolted joint dampingin large structures using finite element (FE) software. LÄS MER

  5. 4. Modelling of a Glued Bolt Joint in Finite Element

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Tove Boivie; [2023]
    Nyckelord :Solid Mechanics; finite element method; adhesive; bolt; hybrid joint; Hållfasthetslära; finita element metoden; lim; skurv; hybrid förband;

    Sammanfattning : 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. LÄS MER

  7. 5. Modeling of a ball contact with a coated plate

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

    Författare :Mohammadreza Saeedi; [2023]
    Nyckelord :Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Sammanfattning : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. LÄS MER
