  1. 11. Digital konstruktion samt verifiering av hjulupphängning till JU Solar Team´s solbil 2019

    Kandidat-uppsats, Högskolan i Jönköping/Tekniska Högskolan

    Författare :Marcus Svensson; Arvid Gränsmark; [2019]
    Nyckelord :JU Solar Team; Solar Car; Wheel suspension;

    Sammanfattning : There is a need to improve the JU Solar Team's new solar cell powered electric car's driving capabilities for the Bridgestone World Solar Challenge 2019. Partly to improve the car's safety and the ability to meet the competition requirements, but also to minimize effects that contribute to increased rolling resistance. LÄS MER

  3. 12. TWIST : Twelve Bar Intelligently Simulated Tensegrity

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Hannah Petersson; [2019]
    Nyckelord :tensegrity; robotics; simulations; monte carlo method; central pattern generators; lander; space;

    Sammanfattning : One of the biggest challenges of putting a robot on an extraterrestrial surface is the entry, descent and landing. By making the robot impact resistant, the need for landing thrusters and parachutes is reduced, lowering the weight and cost of an interplanetary robotic mission. LÄS MER

  4. 13. Shock Absorbing Flooring For Elderly Homes : Study of Shock Absorption of Head Impacts and Rolling Resistance

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

    Författare :Brynjar Hilmarsson; [2018]
    Nyckelord :Shockabsorbing Flooring; Rolling Resistance; Fall Injuries; Head Impact Studies;

    Sammanfattning : In Sweden fall-related injuries among the elderly lead to over a thousand deaths and close to 300.0000 hospital visitations annually. Fall related injuries can in many cases lead to serious head injuries along with other fractures. The elderly are more prone to fall and sustain an injury because of conditions such as osteoporosis and weak muscles. LÄS MER

  5. 14. Energy efficient cornering : Simulation and verification

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Nicolas Luco; Keren Zhu; [2018]
    Nyckelord :Bicycle model; Energy consumption; Vehicle cornering behaviour; Yaw moment control;

    Sammanfattning : The purpose of this master thesis is to study the energy efficiency of a vehicle when it is cornering. To achieve this, a Simulink model was built from a simple basic bicycle model and theoretically validated. This model was then analysed and successively improved by adding velocity and yaw moment control. LÄS MER

  7. 15. Testuppställning för uppmätning av rullmotstånd

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Martin Erwe; [2018]
    Nyckelord :Tires rolling resistance; chassis dynamometer; torque wheel; rolling resistance coefficient; Däcks rullmotstånd; chassidynamometer; momentnav; rullmotståndskoefficient;

    Sammanfattning : När en lastbil färdas på väg utsätts den för ett antal krafter. Däckens rullmotstånd utgör ungefär 36 till 60 % av färdmotståndet. Att kunna validera rullmotståndet vid egen testning är värdefullt för en fordonstillverkare som Scania. LÄS MER
