  1. 1. A New Approach for Positioning Human Body Models Utilising the 3D-Graphics Program Blender

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Jesper Eiderbäck; Felix Jahnke; [2023]
    Nyckelord :Human Body Model; HBM; positioning; THUMS; Blender; Radial basis function.; Mänsklig kroppsmodel; HBM; positionering; THUMS; Blender; Radiell Basfunktion;

    Sammanfattning : A finite element human body model (FE HBM) is a detailed virtual model of the human body that, for example, is used for simulating traffic accidents. A problem with HBMs is that there is no simple way to position the HBMs in non-standard positions. LÄS MER

  3. 2. Analysis of Head Kinematics in Ice Hockey

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Sammanfattning : 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. Arm Injury Prediction with THUMS SAFER: Improvements of the THUMS SAFER upper extremity

    Master-uppsats, KTH/Hållfasthetslära; KTH/Lättkonstruktioner

    Författare :Mariam Bayat; Nichakarn Pongpairote; [2020]
    Nyckelord :Biomechanics; upper extremity; arm; validation; Total HUman Model for Saftey THUMS ; Finite Element Modelling FEM ; Biomekanik; övre extremitet; arm; validering; Total HUman Model for Saftey THUMS ; Finite Element Modellering FEM ;

    Sammanfattning : Globally, approximately 1.2 million people die each year due to traffic accidents. Upper extremity injuries account for 18% to 25% of all car accident injuries. In order to be able to analyze these crash-related injuries, Human body models(HBMs) are used as a complement to FE simulations. LÄS MER

  5. 4. Modeling and Evaluation of a Finite Element Cervical Spinal Cord for Injury Assessment

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Nicole Valle Olivera; [2020]
    Nyckelord :Biomechanics; Neuronics; Spinal Cord; LS-Dyna;

    Sammanfattning : Motor vehicles collisions and falls have gradually increase the risk for spinal cord injuries. An increased knowledge of the spinal behavior and its injury mechanisms can be used as preventive strategies. LÄS MER

  7. 5. Modelling of Whiplash Trauma Parametric study of rear-end impacts using FEM and CFD

    H-uppsats,

    Författare :Andreu Oliver González; Mourya Vanama; [2019-07-03]
    Nyckelord :Farkostteknik; Strömningsmekanik; Vehicle Engineering; Fluid mechanics;

    Sammanfattning : This work is a combination of Finite Element (FE) modelling and Computational Fluid Dynamics (CFD) to investigate the effect of acceleration pulses, head restraint and seating posture on facet joint loads and pressure transient magnitudes on the neck injury outcome during whiplash motion. A parametric study is carried out with the FE human body model THUMS (Total HUman Model for Safety) for a variety of crash pulses and crash conditions that have a known relative risk of long term neck injuries in rear-end impacts.
