  1. 21. 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.

  3. 22. Design of a screwless radio enclosure.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Oskar Lundkvist; [2019]
    Nyckelord :Enclosure; radio; screwless; snap-fit; Inkapsling; radio; skruvlös; snäppen;

    Sammanfattning : Radior är en viktig del av mobiltelefoninätverket. De är kopplade till antenner som trådlöst skickar och tar emot radiovågor. Kraven på inkapslingen av telekommunikationsutrustning ökar kontinuerligt. Ett sätt att minska vikt, storlek, monteringstid och förbättra utseendet av radior kan vara att ersätta skruvar med andra fästprinciper. LÄS MER

  4. 23. Computational modeling strategy of steel connections

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Författare :Carl-Michael Bjälkensäter; Carl Holmgren; [2019]
    Nyckelord :FEM; steel; connection; joint; Technology and Engineering;

    Sammanfattning : When designing large complex steel structures numerical calculation methods are always used to some extent. The simulation technology of today is advanced and can with proper modeling technique provide detailed analyses which captures the structural response accurately. LÄS MER

  5. 24. Elbow Design, Servo Motor Selection and Control Implementation of the Agile Parallel Kinematic Manipulator

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Hampus Farmängen; Felix Lundblad; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The purpose of this work was to contribute to the creation of a prototype of a new type of robot called Agile Parallel Kinematic Manipulator or AgilePKM for short. Designing, building and controlling a new type of robot is a task which goes beyond the scope of any master thesis project, but there are subtasks which are more suitable to handle within the available time frame.

  7. 25. Modelling of Hand Gestures and Motions

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Erik Ingemarsson; [2019]
    Nyckelord :Radar; Gesture Recognition; Signal Processing; Technology and Engineering;

    Sammanfattning : Measuring the radar response has proven to be a valid input for neural networks used for gesture and motion recognition. Previous work have been based on measuring the radar response of hand gestures, but it has been shown that models based on the analytic expressions for basic objects are useful when simulating larger motions, such as pedestrians.
