  1. 16. Life extension of welded steel details in bridges

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Zhelei Jin; [2023]
    Keywords : Welded joints; Fatigue; Pre-fatigue; Life extension; Fracture mechanics; Finite element analysis; HFMI; ; Svetsade fogar; utmattning; förutmattning; livsförlängning; frakturmekanik; finit elementanalys; HFMI; ;

    Abstract : High-Frequency Mechanical Impacts (HFMI) is a surface treatment technique utilized to introduce residual stresses and extend the service life of structures. This project primarily focuses on studying the life extension effects of HFMI on welded structures that have undergone fatigue and have existing cracks. READ MORE

  3. 17. Numerical Tool for Thermal Analysis of Space Computers

    University essay from Uppsala universitet/Elektricitetslära

    Author : Baran Hamad; [2023]
    Keywords : thermal; space; thermal analysis; thermal design; space computer; heat transfer; PCB; lumped parameter; lumped element; thermal resistance; termisk; rymd; termisk analys; termisk design; rymddator; värmeöverföring; PCB; lumped parameter; lumped element; termisk resistans;

    Abstract : This master thesis addresses the development of an automatic numerical tool for thermal analysis, focusing on thermal systems comprising a printed circuit board assembly and cooling case structure. The project, conducted in collaboration with Unibap, aims to enhance the design process of space computer modules by automating middle steps between design software and thermal analysis results.

  4. 18. Analysis of combined response of railway bridge and track : A parametric finite element model of the bridge across Bryngeån

    University essay from KTH/Bro- och stålbyggnad

    Author : Moa Nolinder; [2023]
    Keywords : ;

    Abstract : When designing a railway bridge it is common to consider and designthe bridge structure and the track structure separately. However, theyare connected and that interaction generates a combined response and aforce transfer between them. READ MORE

  5. 19. Development of Elastic Mechanism for actuation of Valve

    University essay from KTH/Maskinkonstruktion

    Author : Nidhi Menon; [2023]
    Keywords : Compliant mechanism; Engine; HGR valve; Heat gas recirculation; Eftergivlig mekanism; HGR-ventil; läckage; varmgasåtercirkulationsventilen;

    Abstract : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. READ MORE

  6. 20. Approximating Damping Coefficient of Bolted Joints using the Finite Element Method

    University essay from KTH/Hållfasthetslära

    Author : Abhiroop Chatterjee; [2023]
    Keywords : ;

    Abstract : 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. READ MORE
