  1. 1. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Pranay Kumar Parsi; [2023]
    Keywords : Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

    Abstract : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. READ MORE

  2. 2. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
    Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

    Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

  3. 3. Tribology of Polymer Composite with Low Load Application for Automotive Industries

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Martin Asuquo; [2022]
    Keywords : ;

    Abstract : In recent times, there has been an increased interest in replacing conventional metals and synthetic fiber composites in various automobile parts with natural fiber polymer composites. These natural fiber composites offer benefits over conventional materials in terms of reduction in weight, lower cost, comparable high specific properties such as specific stiffness and strength, low abrasion property, and availability of these materials.

  4. 4. Design and evaluation of a shock load resistant dynamic chain plate

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Daniel Olsson; [2022]
    Keywords : Dynamic; chain; shock load; Simulink; FEA; conveyor; wear; experimental; Nordic Quick Systems; chain plate; Simulation; FEM;

    Abstract : Conveyor chains are often subject to repetitive shock loads during normal operations. This can cause accelerated wear in the chain leading to premature chain replacementor chain failure (Otoshi, 1997, p. 4). In this thesis a new approach for reducingshock load related wear in conveyor chains is proposed. READ MORE

  5. 5. On the friction and failure mechanisms of bearing and gear surfaces lubricated by a novel nanoadditive in highly stressed operating conditions

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Diego Manuel Chamorro Ruz; [2022]
    Keywords : micropitting; nanoadditive; gear; bearing; tribology; rolling contact fatigue;

    Abstract : Obtaining an enhanced lifespan for mechanical transmissions has become a challenge in diverse application sectors. Micropitting as a contact fatigue mechanism has seriously jeopardized the well-being of rolling-sliding elements present for instance in gearboxes. READ MORE
