  1. 16. Design of footbridges subjected to dynamic loading

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Pontus Brynk; [2022]
    Keywords : Dynamic design; footbridges; SETRA; pedestrian loading; Technology and Engineering;

    Abstract : Modern design of steel pedestrian bridges often results in relatively light constructions with low natural frequencies were there is a considerable risk of resonance to occur from loads due to pedestrians. To resolve the problem a common solution is to increase dimensions of load bearing elements, resulting in greatly oversized elements with increasing costs and have substantial environmental impact.

  3. 17. Analysis of Head Kinematics in Ice Hockey

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : David Pogosian; [2022]
    Keywords : Ice hockey; Video analysis; MPS; THUMS; Concussion; Head kinematics; Finite Element analysis; Ishockey; Videoanalys; MPS; THUMS; Hjärnskakning; Huvudkinematik; Finita element metoden;

    Abstract : Ice hockey has been identified as a sport with a high risk for concussions due to it being highly physical. Improvements have been made over the years to improve the protective gear for the players effectively eliminating more severe traumatic brain injuries (TBIs) however mild concussions (mTBI) are still prevalent to this day.

  4. 18. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

    University essay from KTH/Hållfasthetslära

    Author : Ludvig Dahlin; Ebba Larsson Regnström; [2022]
    Keywords : FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

    Abstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

  5. 19. FE Simulations of Mounting of an Anisotropic Work Piece Material to Reduce the Effects of Vibration

    University essay from Lunds universitet/Industriell Produktion

    Author : Punith Prakash; Sudarshan Girigimallayanapalya Shivanna; [2021]
    Keywords : Optical cavity; Anisotropy material; FE simulation; Modal analysis.; Technology and Engineering;

    Abstract : Optical cavities should be designed to be insensitive to vibration in all directions. The study of the behavior of the material used to develop an optical cavity is vital for the cavity to be insensitive in all orders. READ MORE

  6. 20. Influence of load distribution on trough bridges

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jacob Gustafsson; [2021]
    Keywords : Bridge; Trough bridge; Concrete; Load distribution; Ballast;

    Abstract : There are approximately 4000 railway bridges in Sweden and a common construction type is the short span concrete trough bridge. With the current standards the load distribution through ballast is assumed to be uniformly distributed with a distribution slope of 2:1 according to the Swedish Administration of Transport or 4:1 according to Eurocode 1.
