  1. 1. A final drive device for torque vectoring in small racing cars

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Sven Kalkan; [2023]
    Nyckelord :Torque vectoring; differential; formula student; racecar; racing; BorgWarner; product development; Technology and Engineering;

    Sammanfattning : The agility of the car can be improved by distributing the longitudinal tire forces unevenly between the wheels. The resulting yaw moment helps the car to steer in transient driving scenarios, like on a slalom course. The available grip in steady state cornering can also be increased along with stability.

  3. 2. Mechanical Design, Analysis, and Manufacturing of Wind Tunnel Model and Support Structure

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Sara Ghika; [2021]
    Nyckelord :Aerospace; wind tunnel testing; lightweight structures; UAV; Mekanisk Design; Analys och Tillverkning av Vindtunnelmodell och Stödstruktur;

    Sammanfattning : This volume covers the phases from design to manufacturing of a wind tunnel test support structure for a conceptual blended wing-body UAV designed by KTH Green Raven Project students. The innovative aircraft design demonstrates sustainability within aviation by utilizing a hybrid electric-fuel cell propulsion system. LÄS MER

  4. 3. Dimensionering och konstruktion av passiv mekanisk pitch för småskaliga horisontalaxlade vindkraftverk

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Sammanfattning : För vindkraftverk i mindre skala används i huvudsak två sätt att avlasta vid höga vindhastigheter, stallreglering och girning ur vind. En tredje metod är att pitcha rotorbladet till en mindre attackvinkel. Då minskar belastningen på rotorbladet samtidigt som effektgenerering kan bibehållas. LÄS MER

  5. 4. Numerical study of the effects of wind-tunnel conditions on a passenger vehicle in crosswinds

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Sahil Gupta; Vivek J Shah; [2020]
    Nyckelord :;

    Sammanfattning : Wind tunnel tests is a necessity when it comes to study of aerodynamic flow field around vehicle in its development process. However, there are certain limitations on physical wind tunnel tests during vehicle development process. This includes high running costs and interference effects due to blockage and boundary conditions. LÄS MER

  7. 5. Electronic Control Unit for Automatic Control of Torque Vectoring

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :John Huzell; Johan Göransson; [2020]
    Nyckelord :torque vectoring; electronic control unit; automatic control; yaw moment; CAN; PCB; Formula Student; Technology and Engineering;

    Sammanfattning : Torque vectoring for automobiles is used to increase cornering speeds and improve road safety by manipulating the car's wheel-speeds. One method of torque vectoring for a rear-wheel-drive Formula Student race car is using a dual-clutch to slip the inner wheel thus create a yaw moment during cornering. LÄS MER
