  1. 1. Electrically powered manoeuvring of water jets

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Joel Engström; [2021]
    Nyckelord :Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

    Sammanfattning : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.

  3. 2. Design and Analysis of Electric Over-actuated Vehicle Suspension

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

    Författare :Ankith Suresh Athrey; [2020]
    Nyckelord :RCV; ITRL; MBD; CAD; FEM; RCV; ITRL; MBD; CAD; FEM;

    Sammanfattning : The main aim of this master thesis is to improve the performance of the Research Concept Vehicle (RCV). The RCV is an electric over-actuated vehicle developed at Integrated Transport Research Lab (ITRL) at KTH Royal Institute of Technology. The vehicle steer, camber, drive, and brake on each wheel of the vehicle. LÄS MER

  4. 3. Design and Verification of MIL for Linear Actuator

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

    Författare :NIKLAS HOLMÉR; [2020]
    Nyckelord :Efficiency; Actuator; Power losses; Modelling; Verkningsgrad; Ställdon; Effektförluster; Modellering;

    Sammanfattning : In a world where development of new technology moves rapidly towards renewable energy resources, it is important to implement new technology for efficiency improvement on existing products. This is Cascade Drives ambition, to enable a shift from hydraulic usage in heavy vehicles to a solution that is completely electromechanical driven, to improve energy efficiency. LÄS MER

  5. 4. Development of Active Rear Wheel Steering and Evaluation of Steering Feel

    Master-uppsats, KTH/Fordonsdesign

    Författare :Suvansh Kasliwal; [2019]
    Nyckelord :;

    Sammanfattning : In the last few years, with the development of sensor and actuator technology along with increased computation power available on-board of vehicles, the automotive industry is em-ploying more and more mechatronic systems for Advanced Driver Assistance Systems (ADAS) and Autonomous Driving (AD). Driver Assistance Systems are being used to increase safety (eg. LÄS MER

  7. 5. Mechanisms for rear wheelsteering on a Formula Student car

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Einar Bremer; Viktor Landemoo; [2018]
    Nyckelord :Formula Student; Four wheel steering; mechanism; Rear wheel steering; Bakhjulsstyrning; Formula Student; fyrhjulsstyrning; mekanism;

    Sammanfattning : In this thesis the requirements for a rear wheel steering mechanism aimed to be implementedon KTH:s Formula Student car were evaluated. The requirements were obtainedby using already known loads, an analysis of how the quickly the driver turns the steeringwheel during track driving from video material and the Formula Student rulebook whichthe car is designed after.
