  1. 6. Design and Qualification of a Gimbal Suspension for Attitude Control System Testing of CubeSats

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

    Författare :Anthony Holmberg; [2021]
    Nyckelord :Gimbal; CubeSat; ADCS; Suspension; Testbed; Disturbance Torque; Angular Measurement; Gimbal; CubeSat; ADCS; Upphängning; Testbädd; Störmoment; Vinkelmätning;

    Sammanfattning : Since the dawn of the space race, satellites have grown rapidly in complexity and shrunk equally rapidly in size. Most of them contain an Attitude Determination and Control System (ADCS) on board for pointing and detumbling manoeuvres. LÄS MER

  3. 7. Modeling, Simulation and Correlation of Drag losses in a Power Transfer Unit of an All- Wheel Drive System

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

    Författare :Balaji Srinivasan Venkatesan; [2020]
    Nyckelord :1-D simulation; System simulation; ROMAX Energy; LMS AMESim; Power loss; Hypoid gear; Power Transfer Unit; Efficiency and Drag Loss Tests; 1-D simulering; systemsimulering; ROMAX Energy; LMS AMESim; effektförlust; hypoidväxel; kraftöverföringsenhet; effektivitet och dragförlusttester;

    Sammanfattning : A Power Transfer Unit (PTU) of an All-Wheel Drive System is a hypoid gear transmission unit that distributes the power from the vehicle transmission to all wheels of the vehicle. This thesis aims at increasing the fidelity of the analytical power loss calculation methods through test data correlation and develop a 1D simulation model that can be used to evaluate the drag losses in the PTU at early design stages.

  4. 8. Bärplan till 505-jolleHydrofoilHydrofoil

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Henrik Lindholm; Anders Fox; Henrik Larsson Sevon; [2019]
    Nyckelord :;

    Sammanfattning : Målet med detta kandidatexamensarbete var att studera möjligheten att använda hydrofoils på en 505-jolle. Detta gjordes genom att utforma en konceptlösning av ett hydrofoilsystem. Systemtypen som valdes för att utvärderas var ett bi-T-foliesystem. LÄS MER

  5. 9. Drag Torque and Synchronization Modelling in a Dual Clutch Transmission

    Master-uppsats, Lunds universitet/Maskinelement

    Författare :Mikael Lund; [2018]
    Nyckelord :drag torque; synchronization; dual clutch transmission; Technology and Engineering;

    Sammanfattning : Noise, vibration and harshness (NVH) is a big consideration in the automotive industry. In order to create an as pleasant driving experience as possible for the driver, NVH should be minimized. One of the sources of NVH comes from the transmission due to the synchronization process.

  7. 10. Model Predictive Control Using Neural Networks : a Study on Platooning without Intervehicular Communications

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Gustav Ling; Klas Lindsten; [2017]
    Nyckelord :MPC; platooning; neural networks; velocity profile estimation; gear shift dynamics; heavy duty vehicle; machine learning;

    Sammanfattning : As the greenhouse effect is an imminent concern, motivation for the development of energy efficient systems has grown fast. Today heavy-duty vehicles (HDVs) account for a growing part of the emissions from the vehicular transport sector. LÄS MER
