    University essay from KTH/Medicinteknik och hälsosystem

    Author : Jia Cheng Xu; [2019]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 23. Control strategies evaluation for stabilizing a quadcopter docking on a side wall.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : EDUARDO FUENTEVILLA BLANCO; [2019]
    Keywords : ;

    Abstract : This thesis contemplates the stabilization of a quadcopter in physical contact with a side wall via a mechanical arm. The drone is accelerated aiming to apply a greater force against the wall. Consequently, the drone adopts a tilted position that must be controlled. READ MORE

  5. 24. Influence of ANS Triboconditioning on friction and fatigue in rolling contact configurations

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Björn Hedmark; Per Wallgren; [2019]
    Keywords : Tribology; friction; fatigue; micropitting; surface engineering; twin-disc; triboconditioning; LTU;

    Abstract : The automotive industry is constantly being challenged by customers and authorities to enhance the efficiency of the internal combustion engine (ICE) in order to achieve improved fuel consumption and reduced emissions. There are several interfaces within the design of an ICE that causes frictional losses, one of them is the valvetrain. READ MORE

  6. 25. Friction and wear study of lean powder metallurgy steel in a lubricated sliding contact

    University essay from Uppsala universitet/Tillämpad materialvetenskap
