  1. 1. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

    University essay from KTH/Hållfasthetslära

    Author : Philip Singh; [2022]
    Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

    Abstract : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.

  3. 2. 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. 3. 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. 4. Investigating the Potential of Jaw Protection to Reduce the Risk of Concussions in Ice Hockey : A Finite Element Study

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

    Author : Katja Marie Berg Papworth; [2021]
    Keywords : Ice Hockey; Concussion; Jawguard; Finite Element; HIII;

    Abstract : Ice hockey is a sport with high velocities and a large number of impacts to the head. The high occurrence of concussions is being recognized, and both short and long term consequences have been found. READ MORE

  6. 5. Analysis of traveler’s behaviorusing electric scooters based on surveys

    University essay from KTH/Transportplanering

    Author : Taha Ali; [2021]
    Keywords : Micro mobility; E-scooters; Travel Behavior; Analysis of travel behavior; Travel parameters; Transport policy; Mikromobilitet; E-skotrar; Resebeteende; Analys av resebeteende; Reseparametrar; Transportpolitik;

    Abstract : In this study, travel behavior for the users of E-scooter is analyzed based on survey questions. The main purpose of the study is to understand the nature of E-scooters users and their preferences as well as analyzing their trip parameters. The survey was designed to cover most ofthe behavioral influential factors. READ MORE
