  1. 1. Heat-pipes in electric machines : Heat management in electric traction motors

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Anton Olofsson; [2022]
    Nyckelord :Heat-pipe; Heat pipe; FEM; LPM; Traction motors; Induction motor; Heat management;

    Sammanfattning : The world is continually changing towards more energy efficient alternatives and less pollution. For the traction market, electric powertrains have become the go-to method, superior to both steam and diesel-electric hybrid systems. LÄS MER

  3. 2. Investigation and evaluation of optical distance sensors

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och system

    Författare :Olof Wigzell; [2022]
    Nyckelord :optics; radiometry; senssor; microcontroller; irradiance; circuit design; calibration; validation;

    Sammanfattning : Optical sensors are among the sensors that are often used for distance measurements. An optical distance sensor is basically made of a light emitter (Tx) such as a light emitting diode (LED), a light receiver (Rx) such as a photosensitive transistor, and a circuit supporting the operation of the Tx and Rx.

  4. 3. Multibody modelling of the vibrations in an aircraft engine

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Charly Mollet; [2022]
    Nyckelord :Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Sammanfattning : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. LÄS MER

  5. 4. Hydroacoustic Modelling of Podded Propulsion System : Underwater Radiated Noise Prediction Using ANSYS

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Martin Persson; [2022]
    Nyckelord :Fluid Mechanics; Computational Aeroacoustics; Frequency Response; Noise and Vibration; Pod; Propulsion System; ANSYS; Reynolds-Averaged Navier-Stokes Equations; Kongsberg Maritime Sweden AB;

    Sammanfattning : Ocean noise pollution is an invisible but growing threat. There are many sources of sound in the ocean but human underwater radiated noise, in particular from shipping is one of the most prominent one. Ocean noise pollution can interfere or sometimes even directly harm marine life. LÄS MER

  7. 5. Control and Autonomy of a Water Quality Measuring Unmanned Surface Vehicle (USV) : Catfish project - Control and Autonomy

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad

    Författare :Vidar Hårding; [2021]
    Nyckelord :catfish; control and autonomy; pixhawk; usv; motor configurations; catfish; kontroll och autonomi; pixhawk; vattendrönare; motorkonfiguration;

    Sammanfattning : This report is about the implementation of autonomy and control on a water quality measuring unmanned surface vehicle. The project was termed Catfish and involved five teams focusing on different aspects of the initial goal to create an autonomous three-part system; a surface drone, a submerged drone and flying drone.
