  1. 1. Gearbox fault detection, based on Machine Learning of multiple sensors

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Armands Krumins; [2021]
    Keywords : condition monitoring; gear; machine learning; surface fatigue;

    Abstract : The increasing demand for higher efficiency and lower environmental impact of transmissions, used in automotive and wind energy industries has created a need for more advanced technical solutions to fulfil those requirements. Condition monitoring plays an important role in the transmission life cycle, saving resources and time. READ MORE

  3. 2. Rotation of man-made floating islands : Evaluation of different design approaches to allow rotational movement in anchoring of a sustainable island

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Mathias Petersson; [2021]
    Keywords : Sustainability; rotation; complex anchoring; anchoring floating objects; man-made island;

    Abstract : Abstract   Background The sea levels have risen about 10 cm since 1993 and will continue to rise due to global warming along with the expected increase in population. The rise will decrease the available landmass for settlements and raw material production. READ MORE

    Abstract : 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. READ MORE

  5. 4. Modeling of a Gear Test Rig : An Investigation of Static Loads and Dynamic Excitation of Vibrations

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Albin Hugoh; [2019]
    Keywords : ;

    Abstract : Today the automotive industry is going through big changes and facing many new challenges due to the transformation to a sustainable transport solution in combination with tougher legal demands. Gears have been around for a long time and it is one of the most efficient ways of transferring rotary motion from one shaft to another. READ MORE

  6. 5. High precision detection of multiple rotating objects

    University essay from KTH/Mekatronik

    Author : David Nikolas Alfred Wallén; [2018]
    Keywords : ;

    Abstract : Denna avhandling har skrivits i sammarbete med en Stockholmsbaserat konst- och designstudio vid namn ''Humans since 1982'' som bygger och säljer modern högteknologisk konst till marknader världen över. Studion ville utföra forskning kring att utveckla och implementera ett system som detekterade och beräknade positionen av två roterande oberoende objekt monterade på två stegmotorer via en växellåda.
