  1. 1. Conceptual design of an electronic dockingstation and positioner for portable antenna

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Otto Egeman; Karl Westling; [2022]
    Nyckelord :Antenna; Automatic positioner; Geostationary; Docking station; Antenn; Automatisk inpekning; Geostationär; Dockningsstation;

    Sammanfattning : The presented work in this report is a master’s thesis at the machine design track at KTH Royal Institute of Technology. The work was commissioned by Ovzon through Svea Teknik AB. The T6 antenna in Ovzons antenna terminal portfolio is as of now fully manual in terms of positioning against satellites. LÄS MER

  3. 2. Design and Evaluation of a Novel Conveyor Utilizing a Screw Mechanism to Move Objects With Integrated Racks

    Master-uppsats, KTH/Mekatronik

    Författare :Måns Nilsson; Mathias Nils Edvin Nordqvist; [2021]
    Nyckelord :Screw Conveyor; Intralogistics; Material Handling; Thread Meshing; Worm rack drive; Brushless motor; Skruvtransportör; Intralogistik; Materialhantering; gängingrepp; Snäckskruv och kuggstång; borstlös motor;

    Sammanfattning : Intralogistics, or material handling, traditionally use roller or chain conveyors to moveo bjects and goods in factories and warehouses. One negative aspect of the traditional types of conveyors is that they are expensive, as they are comprised of many moving parts. LÄS MER

  4. 3. Fault detection of planetary gearboxes in BLDC-motors using vibration and acoustic noise analysis

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Henrik Ahnesjö; [2020]
    Nyckelord :Planetary gearbox; Fault detection; Condition Monitoring; Support Vector Machine SVM ; Machine Learning; Supervised Machine Learning; Defect Pinion; Defect Planet Gear; MATLAB; LabVIEW; Soundproof-box; Noise Vibration Harshness NVH ; Gearmesh Frequency GMF ; Power Spectrum; BLDC-motor;

    Sammanfattning : This thesis aims to use vibration and acoustic noise analysis to help a production line of a certain motor type to ensure good quality. Noise from the gearbox is sometimes present and the way it is detected is with a human listening to it. This type of error detection is subjective, and it is possible for human error to be present.

  5. 4. Prediction of life durability in friction for wet clutches of DCT gearboxes

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Lars-Johan Sandström; [2020]
    Nyckelord :wet clutch; DCT; Gearbox; Durability; Friction; Life; Dual Clutch Transmission;

    Sammanfattning : Many new cars are equipped with automatic transmissions. These gearboxes often have a dual clutch transmission (DCT) that has a built-in wet clutch. The lubricants used in these gearboxes is often very advanced because it must take care of two systems, the wet clutch and the gears. There is always a strive to make the drain intervals longer.

    Nyckelord :statistical; analysis; engine; gearbox; sensor; sensors; rotation; rotational; speed; differential; pressure; performance; characteristics; trueness; precision; accuracy; Hall; inductive; induction; gauge pressure; reference; hysteresis; bias; noise; linearity; non-linearity; DEWESoft; DAQ; wheel; tooth; teeth; absolute; rotary; encoder; matlab; XOR; Gray; binary; LabView; sampling; measurement; measuring; statistisk; analys; motor; växellåda; sensor; sensorer; rotation; rotationell; hastighet; fart; differentiell; tryck; prestanda; karaktäristik; trueness; precision; accuracy; noggrannhet; onoggrannhet; Hall; induktiv; induktion; tryckskillnad; referens; hysteres; bias; avstånd; brus; linjäritet; linearitet; olinear; olinjär; olinearitet; olinjäritet; DEWESoft; DAQ; sampling; mätning; hjul; tand; tänder; absolut; rotationsgivare; givare; matlab; XOR; Gray; binär; LabView;

    Sammanfattning : This thesis provides a standardized method to measure accuracy for engine and gearbox sensors. Accuracy is defined by ISO 5725, which states that trueness and precision need to be known to provide a metric for accuracy. However, obtaining and processing the data required for this is not straight forward. LÄS MER
