  1. 6. Pantograph-catenary wear modelling using dynamic simulation

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Gaston Holmström; [2022]
    Keywords : Wear modelling; catenary pantograph interaction; mechanism; conditional; railway; slitagemodellering; kontaktledning pantograf interaktion; mekanism; konditionell; järnväg;

    Abstract : Wear condition modelling is a research topic which lately has increased in popularitydue to its significance to the railway industry. Large sums are spent on maintenanceof the network every year, which has generated a demand for understanding and predictingwear mechanisms in a multitude of components within both railway vehiclesand infrastructure.

  3. 7. 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

  4. 8. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

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

    Author : Emil Treitler; [2022]
    Keywords : Fatigue; Kaplan; Hydropower; Turbine;

    Abstract : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. READ MORE

  5. 9. High temperature tribological evaluation of a self-lubricating laser cladding with and without external solid lubricant

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

    Author : Cecilia Nemeth; [2020]
    Keywords : high temperature tribology; hot metal forming of aluminium; self-lubricating laser cladding; external solid lubricant;

    Abstract : The purpose of the project work was to build knowledge of the tribological behaviour of self-lubricating laser cladding, with and without external solid lubricant during conditions relevant for hot metal forming of aluminium. The materials used during the project were plates coated with a Ni-based self-lubricating clad and a reference sample of work tool steel. READ MORE

  6. 10. Use of compliant mechanisms in gearbox applications

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Álvaro Manresa Pérez; Ander Gonzalez Sanchez; [2020]
    Keywords : compliant mechanisms; product development; Finite Element Analysis; additive manufacturing;

    Abstract : The purpose of this thesis is to prove that the use of compliant mechanisms in gearbox applications is viable. Compliant mechanisms are developed for their implementation in Scania’s hybrid asynchronous gearboxes. READ MORE
