  1. 1. 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

  3. 2. 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.

  4. 3. Evaluation of Thoracic Injury Risk of Heavy Goods Vehicle Occupants during Steering Wheel Rim Impacts to Different Rib Levels

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Jia Cheng Xu; [2019]
    Nyckelord :Heavy Goods Vehicles HGVs ; Rim Impacts; Human Body Models HBM ; Total HUman Model for Safety THUMS ; Hybrid III; ribs; aorta; liver; spleen; injury risk functions; material models; cumulative distribution function CDF ; Ogden; risk curves; Lastbilar; rattislag; humanmodeller; Total HUman Model for Safety THUMS ; Hybrid III; revben; aorta; lever; mjälte; riskfunktioner; materialmodeller; kumulativ fördelningsfunktion; Ogden; riskkurvor;

    Sammanfattning : The interior of heavy goods vehicles (HGVs) differs from passenger cars. Both the steering wheel and the occupant are positioned differently in a HGV and increases the risk of steering wheel rim impacts. LÄS MER

  5. 4. Evaluation of Knee Ligament Injuries in Occupants of Heavy Goods Vehicles by Simulating Frontal Impacts using THUMS HBM

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

    Författare :Jiota Nusia; [2019]
    Nyckelord :Frontal impacts; Cumulative injury risk curve; Ligament material curves; Total Human Model for Safety THUMS ; Hybrid III- model HIII ; Heavy Goods Vehicles HGV ; Validation; Knee joint; Posterior cruciate ligament PCL ; Medial collateral ligament MCL ; Lateral collateral ligament LCL .;

    Sammanfattning : INTRODUCTION. Frontal collisions have been observed to cause the severe injuries on heavy goods vehicle occupants, and the lower extremities have been frequently injured. Injuries of knee joints are rarely life threatening, however they tend to give long-term consequences. AIM. LÄS MER

  7. 5. Improvements and Validation of THUMS Upper Extremity : Refinements of the Elbow Joint for Improved Biofidelity

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

    Författare :Kristín Sverrisdóttir; [2019]
    Nyckelord :Upper extremity; elbow; biofidelity; validation; Total HUman Model for Safety THUMS ; Finite Element Modeling FEM ; Övre extremitet; armbåge; biofidelitet; validering; Total HUman Model for Safety THUMS ; Finite Element Modellering FEM ;

    Sammanfattning : Introduction One out of five reported motor vehicle collision injuries occur to the upper extremities. Certain parts of The Total HUman Model for Safety (THUMS) lack validation against experimental data, including the elbow. LÄS MER
